28:06 Fun fact, the folks at Wikipedia have actually gone through the research and found that the original census actually miscounted a single county that had 450 people living in it. So, it actually isn't a transpose error where somebody flipped a digit. The original source is off by 450, and it happens by coincidence that 490 + 450 = 940. How wild.
@@JoCE2305 I agree with you. A transcription at some point is far more likely. The transcription may well have occurred at a more local level and the difference would be carried forward in the total. BTW, any transposition (reversal) of two sequential digits in a number will yield a difference that is a multiple of "9". So the original mistake (if it was a transcription error ) could have occurred by using 160 in place of 610 (which again has a difference of 450) or any of several other number pairs. [ in book-keeping, back before spreadsheets addition was often checked by doing it twice. If two sums were off by some amount that was a multiple of 9 it was always a good practice to look for a transposition error between the two sets of numbers ]
@@howard5992 See above. They did appear to actually miscount rather than transposing digits. They were unsure about the status of a single county containing 450 people. Or so the story goes.

Some years ago I was writing code and I came across this exact problem in a different context. I didn't want to spend too long thinking about it, so came up with Hamilton's method and wrote a quick and dirty implementation of it. I remember at the time thinking that there must be a proper mathematical solution somewhere, but that it wasn't important enough here to waste time on. I'm surprised to learn that not only is there no "fair" solution that always works, but also that the US Federal government took the same bodge-it approach I did!
That’s literally how the US Congress does anything. “Oh no the deadline is tomorrow and we’d have to furlough hundreds of thousands of federal employees if we don’t drop our charade, let’s pass a temporary budget that lasts three months so that we can go home for Christmas without people yelling at us”
Speaking of clerical errors, you've got one in the video. At 16:45 the resulting values for =POP/DJ are being displayed using the final divisor, not the initial estimate 930. Which is also how I could tell that the excel/spreadsheet magic was just smoke and mirrors! Clever editors
It also means his presumption for that instance is incorrect; there was no further rounding or adjustment needed. The numbers came out fair after one adjustment.
It is pretty awesome though that they actually go through the effort of showing enough detail to teach the viewers how to use spreadsheets to do this all on their own!
Wow, the production quality of these videos is rocketing up faster than New Triangles fraction under the Jefferson method! Even the little things, like sharing a cleaned up spreadsheet without all the grid lines and the whole UI up top adds so much to the visual clarity of the math itself. Keep it up Matt!
At 16:33, you've claimed that POP(New Triangle) / D_Jeff(930) = 24.8614, rather than the correct ~23.5247. Notably, in your next column, you've fixed the issue with the rounding down correctly recommending 23 seats, but it's still a very baffling error if you don't get out a calculator and do the division yourself. The error also carries over for Circula, where you've listed the incorrect value of 11.0375 rather than the correct 10.4441, though your floor function still works. Actually, looking a little closer, that whole column appears to be in error, as though you used a divisor other than 930. It's simply that New Triangle and Circula end up being off by a whole seat, so when you fix the equation in the next column that also takes the floor of each number, it's readily apparent for them.
I guess the devisor used was 931 instead of 930 but the issue there would have been that the total number of seats after rounding down would add up to the required 43 making the next part of the video obsolete.
@@FabioNiewelt No, it wasn't 931 - the incorrect numbers were too large, meaning that divisor used to get them was smaller than expected (930). It might've been one of the other lower divisors discussed later in the video, and you can use some algebra to figure out what it was, but I'm not quite that much a stickler for fixing Matt's Parker Squares.
His ENTIRE Excel spreadsheet formulas become convoluted at some point, and it just exponentiates the errors. Later on, around 16:30 ish mark, it is rounding down numbers in an incorrect way. 11.x goes to 10 for example for circle. This throws the amount of seats off by 1. A 2% error.
This reminds me of a similar problem I ran into when writing an RPG engine back in high school (circa 2003 I believe). I was treating character level as a percentage scalar to total attribute values but wanted to distribute attribute increases consistently at every level, so rather than do each attribute individually I decided to increase the total attribute pool itself, then distribute that pool proportional to each attribute's base value. So, for instance, the initial pool was 20 points per character with a 20% increase per level, meaning I wanted 4 new attributes to be automatically distributed with each level up. The problem I quickly ran into was that using the Hamilton method (without knowing that's what it was; it was just the first solution I stumbled upon), was that the 20% increases led to beat frequencies where occasionally the fourth and fifth highest remainders could be **ties** from attributes with identical bases, meaning no exactly-4 increase was possible with that method. In the end I just scrapped it for a round-down approach that had increment spikes on the beat frequencies, since I felt having every 5th level be the one where **every** attribute increases made for a better RPG style "milestone" feel anyhow.
Or the fact that every data science library divides trust data up using Hamiltons method that every program discovers and is used for non political scientific research
@@HesderOleh I'm talking about k-folds cross validation. So k equal partitions of a dataset. This means you can just divide out the remaining ones by fractional % which are all the same anyway. But the fact is you take the rounded down amount and just assign up to 1 more as needed to get the closest to an even partitioning as possible without discarding data
A very similar problem comes up in typesetting when splitting lines evenly into a paragraph. A native solution tries to minimise the total divergence of spaces between words from the average, but that can result in one line being very bad (for example, two words on the line with a massive space between them) while all the others are okay. The fix is to minimise the average of the squares of the divergence; I believe that’s what Don Knuth’s TeX system does (I worked with it back in the 90s, so forgive me if my recall is bad). There are also strange Alabama-like paradoxes caused by the fact that although spaces can be stretched and shrunk smoothly, words do not normally stretch or shrink and jump from one line to another unpredictably as wrap width changes or new text is inserted. I spent a happy but confusing 9 years working on typesetting software and have scars to prove it.
This is why justifying a table of contents is my least favorite and most time consuming part of writing any paper. Why don't all the lines end at the right margin? Why are all my numbers misaligned? Why isn't each character "space" the same width, or each line the same number of spaces?
16:34 - your POP/DJ figures are out here! Although weirdly column E rounds down ‘correctly’ using what should have generated. Did you input Jeff’s divisor as 880 as a test at some point? 🤔 Edit: ah, 880 comes later! Another Edit: Adams’ POP/DA figures for all states except New Triangle, all jump straight to your 960 conclusion on first entry, same issue.
Yes, you are right, it seems we have some hold-over numbers in the animation. My fault for not double-checking everything again! But as you thankfully noticed: the final values are all right, we're just displaying 880 instead of 930 in the intermediate column. Annoying and a bit confusing, but at least the results still stand.

The 3/5's clause was about slaveowners not being able to buy more representation. The free states didn't think the slaveowners should get more representation just for keeping more slaves who couldn't themselves vote or leave. The southern states obviously thought slaves should count as part of the population, not because they believed slaves were entitled to rights or dignity, but because it meant they'd have disproportionate political power.
I always thought that when I was younger. I said "hold on, why would the slave states want their slaves to be worth less when they could have more power"?
@@MOOBBreezy Right, abolitionists were of the position "if they must be slaves, you don't get to steal any of their voting power".

The problem, of course, is integer representatives. But you don’t have to solve that issue by chopping up representatives, instead you could fractionalise the power of their vote to match the size of their representation. This then causes problems with voting because the votes are no longer equal, but it could be argued that’s the only way to be truly fair with integer representation.
Yes that could really work... although that could do interesting things to the power dynamic to the individual representatives in the house. Also worth considering whether you would have 3 full voting reps and one with a 1/3 or everybody gets 2/3 of a vote or something like that.
@@DRicke Or just make the actual house smaller (50 members) and give each member the weight their state brings.

That whole problem stems from trying to squeeze between 2 rigid rules: divisor & max seats. If we left the divisor uniform & the max seats flexible, it works fine. In the beginning, the divisor was 30,000. The populations round naturally up or down, except when the result is
That's the downside of having to actually fit these people in a physical location. If we'd actually used the original uniform divisor of 30,000 we'd currently be at about 10983 seats, which puts us into stadium territory at a minimum. Per Wikipedia, all NCAA FBS college football stadiums except for one in Hawaii would hold it, but only 77 out of 360 NCAA Division I basketball stadiums could hold that house of representatives. Considering the US Capitol building was designed in 1792, they didn't foresee the growth the country would experience. Beyond that, a full stadium complex behind the capitol building might ruin the view for those looking at the Mall.
@@MrSJPowell Thus as population grows, the divisor has changed: 50,000 then 75,000 then 100,000 to ~750,000 today. That's what I'm saying SHOULD be flexible. If the max seats is 435 (as current), adjust the divisor until the natural rounding gets you as close to 435 as possible without going over. The paradox comes in w seat 435 when it naturally lands at 434. There is NO extra seat, just leave it at 434.
Actually, I was thinking just that. What if the rules allowed also the addition/subtraction of seats based on the proximity of divisor to the last allocated seats? Pretty much what you said (but I thought allow going over in case going under falls too short): Start with 435 targeted seats and allocate an actual number between 434-436 based on the outcome.
@@IHateUniqueUsernames I agree it could fall into a range of values, but physical limitations would produce a hard upper limit. I am also wondering how to handle the excessively high divisor issue. 750,000:1 seems a bit excessive to me.
@@taripar4967 Considering the current state of the country, I doubt such a split would be amicable. However, if it had been planned for a split from the beginning, it might have worked better. We almost had it in the 1860s w/o planning. Your idea mirrored my original thought: geographic regional governments between state & federal. The main problem is checks & balances between regional vs federal vs state. If the House alone was regional, it would effectively split the House into x separate Houses. Any bill would need to pass all x to pass the House. W 11,000 reps, legislation would effectively STOP being passed. (Not that that would always be a bad thing.) But it would be of little difference than running the bill by each state house individually. Reconciliation would take forever.
I still find it funny that all these methods have different names in different places. In Germany the Hamilton method is called Hare-Niemeyer, Jefferson is called D’Hondt, and Webster is called Sainte-Laguë.
Another interesting thing to look at I think is, what if we don't require an exact number of representatives. What if we just use that number as a target number and if it deviates slightly after rounding (up/down/closest integer) we just have a few empty or extra seats until the next census?
Or, we just remove bits from the fractional representative? I suppose then the problem is, is that you'd need to do a proportional lobotomy but that has the risk of making the representatives more effective.
The number of seats used to go up as the population did, but it was locked at 435 by the Apportionment Act of 1929. If we had kept increasing it to keep the ratio closer to balanced between the states we would have over 1000 reps now, which would 1)require expanding the physical building where they meet and 2) really change the electoral college.
Am i confused or are the numbers wrong at 16:49? He started talking about the jeff method with dj rounding stuff, but rounded the 24.8 down to 23 and 11.03 down to 10. Looks like he used the wrong box for the dividing
Indeed, there's something wrong there, but he typed D5 and the correct cell got highlighted, so can't be the wrong input value. And funnily enough those are the 2 missing seats.
I also realized this is almost exactly the same thing I had to do when creating a group price calculator. One where I could take any given sale group price and divide it evenly amoungst the diffrent original prices to get the same discount. But I also wanted the sale prices to be rounded to the nearest whole dollar for ease of entering into the system and understanding, which meant a whole lot of rounding and the differences that came with it. Adding a dollar here or taking a dollar off there.
29:45 fun fact, the "slaves are 3/5 of a person" thing was actually *opposed* by the slave states, who wanted them as full people. The 3/5 would deflate their population and reduce their political power.

Quite frankly: too many people. Not only does the house get locked up already with far fewer people but then the issue of finding/creating venues that can seat everyone arise and that need is increased with every passing census. There’s countless more issues but basically it’s good in theory but impractical in execution.
@@wolftamerwolfcorp7465 "Too many people" is easy to solve. Update the divider in every election, to keep the total within set boundaries (e.g. 290-300).
I think this explains something I'd been wondering about for a while. In Australia the number of MPs is supposed to be *approximately* twice the number of senators - it's important to maintain a consistent ratio for the case of a joint sitting. I have often wondered why it's approximately rather than exactly two-to-one until now: the quota rule vs Alabama paradox only applies if the number of seats is fixed. If you have a bit of wiggle room to change the number of MPs (as is the case) you can avoid both issues!
I love his naked honesty. It’s a breath of pure, fresh air in the atmosphere of bad YT content. I had no real concept of how complicated it is to create and maintain a fair system of governance. (And it’s a shame that recently we don’t seem to care much for fairness.) Also, I like history.
This is just the beginning. Look up arrow’s theorem, and the pros and cons of the shortest split line method and other districting methods, and different ways to count votes such as condorcet, Borda, runoff, range voting etc.
Honestly, the issue of representatives is a *TINY* one compared to the problem of the senate, in which 50 senators--potentially representing the 25 smallest states--potentially with the least educated populaces, can bring the entire legislative process to a grinding halt, which is what we see right now. Democracy has an inherent fatal flaw--in that it gives one vote to one person, regardless of how intelligent that person is. That is, if you had a disease, would you value the opinion of 50 Google MDs, or one actual medical specialist? The fact that we have absolutely no way of assessing knowledge of civics, ethics, modern-day issues, foreign policy, economics, mathematics--ANYTHING AT ALL--and then let the most easily conned imbecile cast the same vote as a PhD scientist--is the reason we had the orange turd that was Donald Trump.

You could do a follow-up on seat allocation in the German parliament. It get's really messy due to a mix of proportional and local representation which means not only the allocation of seats between parties is hard, but the number of total seats changes depending on the election results.
Well the problem in Germany is, that they stuck to single member districts. If you joined up districts so you had 5 old districts in every new district and then elected 5 members from every district, then the representation error for each new district would be much go down. Therefore you would need to use far fewer members to make parliament proportional. Then you could set aside a fixed number of extra seats to even it out... and yes I am Dane in Germany shamelessly advocating the Danish system ;-D
Or alternatively, you drop the seat limit entirely and figure out the size of seat based on a divisor of the population of the smallest state, and multiply out. That way as populations change you get automatic switching and remain fairly consistent.
@@fresh_dood True, but if you consider that Wyoming has a population of ABOUT 580k, divide by two to have at least two representatives per state and divide the population of the US (331 ish million) by 580 thousand, you get about 1100 representatives. This is a lot more than they currently have, but every single one represents a district of basically equal size, and 1100 is sort of on the high end of what is practical. It's also better as a system because it keeps the representative ratio lower which is generally quite good.
@@Peter-iq9yy 1100 is absolutely not practical. It's impossible to have a functioning legislative body formed out of that many people. Besides the inherent difficulties to getting such a huge crowd to agree on anything specific, the human mind isn't even capable of keeping track of 1000 people so the representatives would be unable to communicate effectively between each other. And at that point power naturally reverts to a small elite among the representatives, smaller committees, and, especially, to political parties. Which is why past a certain point adding representatives is meaningless, as in the end political groups like parties end up having to make the actual decisions so that what actually matters is the fraction of the chamber each group controls rather than the opinions of most individual representatives.
Did I miss the part where it's explained *why* apportionment systems have to either break the quota rule or have "Alabama paradoxes"? Where can I go to find the proof that no algorithm can avoid both kinds of unfairness?
I was curious about this too and found something called the "Balinski-Young Theorem". It includes a "population paradox" in addition to the Alabama paradox. In the population paradox a small state with rapid growth can lose a representative to a large state with slower growth. According to the Balinski-Young theorem it IS possible to create a method that follows the quota rule and doesn't have an Alabama paradox but it will have a population paradox. A method can avoid the population paradox and the Alabama paradox but then it will have issues with the quota rule for certain values. I'm no mathematician so I can't explain the proof but it certainly is interesting. en.wikipedia.org/wiki/Apportionment_paradox#Balinski%E2%80%93Young_theorem

You must have missed it, because he definitely showed the proof, and he explained it, very thoroughly. He even wrote a song about it, to make it easier for kids to remember, and he paid Tom Brady and Lebron James to sing it together, along with some old man dressed up like Santa Clause, and Big Bird from Sesame Street. I don’t know how you could’ve missed that. There might be something wrong with your Internet, but I bet you just weren’t paying close enough attention. Try reloading the video, and then watch it again at 0.5 speed. If that doesn’t work, then you might have to upgrade to RUclips Premium, and eat some wild mushrooms like I did. Good luck.
The basic reasoning is that when you use the quota rule, you’re left with a bunch of fractions of seats that you must round with. The 1 tenth decimal place value is completely independent and not causally related to the whole number of seats a state is allocated, and it is also the way the remaining seats are allocated. So the subsequent rounding ends up giving out a bunch of arbitrary or “unearned” seats to states. Since these unearned seats are almost randomly given out, increasing the total number of seats can randomly take them away as well. So you end up with the Alabama paradox. It isn’t really a paradox though. We only think it’s unfair to lose a seat because we assumed the original allocation was fair in first place. In reality, Alabama just loses the random advantage that gave it a seat it didn’t necessarily ‘deserve’ in the first place.
Yes you can have a system that obeys both: you just vary the total number of seats. The problem is having a fixed number of total seats instead of just assigning seats proportionally without an upper or lower limit. Why do you need 299 total seats? Just have seats equal to the number that is most accurately representing the population proportion! If that means one census you have 300, fine, if the next is 298, also fine - as long as the partitions are properly represented in percentage.
As math system it would work. But as a real life situation with constitution changes and other juridical details as well as persons who benefit from how the current system works - it would never happen.
The problem with this method is, if done, the states then have to follow a similar system of division... which is often politically gerrymandered to favor a particular political party (both of the American political parties are guilty, just depends on the state in question). So, every 10 years, every state would then have to (get a chance to) redo their house district maps for federal representation. Ultimately, the likely best solution (since the USA is and likely will remain a two party country for the foreseeable future) is to leave the Senate with 2 seats per state. The House converts to proportional representation based upon the political parties. (Like many European nations.) This... will likely never happen, though.
@@terr281 Would you take me through your reasoning again? I fail to see why a variable number of delegates (according to a fixed "1 delegate per every x-thousand state inhabitants" formula) would increase gerrymandering problems, or how the specific method used to determine the number of delegates/districts should positively or negatively influence gerrymanderbility.
This video hits curiously close to my interests. Apportionment, and public choice mechanisms more generally, is something I find fascinating - especially all the many, many ways in which our obvious mechanisms and measures are incompatible.

I had to deal with this when splitting tips between people at a pizza place. Dividing total tips by total hours worked and then multiplying individual hours worked to find how much they earned. Most of the time, the rounding was easy and fair but every so often, we had to give out more tips than we brought in due to rounding. Luckily, I just took money from managers first (I was one, don't worry) and it usually worked out.
It's illegal under federal law for owners, managers, and supervisors to participate in a tipping pool at all, even if they provide direct table service, so I'm still a bit worried...
I always thought the "Alabama paradox" was when you went back in time to meet a distant ancestor, but--in a dramatic twist--it turned out that actually that relative was always you, so you have to stay in the past and fill the role to prevent yourself from disappearing.
Hi Matt, I just watched this very entertaining Video and I'm from Germany! Over the last 15 years we had a very strong debate about how to allocate our seats in the Parliament proprtionally to voters. At this point we had 3 different aproaches all passed into law then later being anulled by the constitutional Court for not being fair enough. I thought you could weigh in and explain why its so difficult to figure it out fairly. Here are some fun facts about the german system that make the maths so difficult: - Germany is divided into 299 little parts and each of them elects one member 1st past the post (simple) we call that the "Die Erstimme" - after that we take another 299 Seats and use them to rebalance the Parliament so that every party gets representation roughly equal to their amount of voters. We call that the "Zweitstimme". - the complication to the second rule is that we do that rebalancing not for whole country at once but for each of the 16 federal states individually. this leads to the problem that the bigger party's get more first past the post seats than they should get even in the full 598 strong house after rebalancing. So tjose bigger partys just get these on top of the 598 which leads to us having more seats overall. we camm the Überhangmandate - Now that the Parliament has more seats the Divisor changes (YAY!!!) which leads to all parties getting more seats we put the on top again we call "Zusatzmandate" - After all of that the bigger parties still come out unfairly ahead so we put in even more seats this time only for parties that didn't get any "Überhangmandate" we call these extra seats "Ausgleichsmandate" In the End we have between 603 (2002) and 736 (2021) but depending on the votes it could even go past 900 Have fun getting all this mess organized maybe you can find a solution. At the Time of me writing this we haven't had a constituionally valid Voting legislation for more then 15 years!
These considerations are mostly independent from the basic method used to turn percentages into number of seats. For that, we currently use Webster's method (i.e. using a divisor and "ordinary" rounding). Webster's method is also used a second time, to further split up each party's seats among the 16 states, according to the number of votes in each state. Also there's no state-level "rebalancing" as you described; the total number of seats for a party only uses the federal result. "Überhangmandate"+"Ausgleichmandate" actually just operate by increasing the size of parliament first, then doing an ordinary round of Webster's method; and the size of parliament was chosen do accommodate for all the direct mandates (in a somewhat complicated manner that does take individual states into account). Well that was how it worked until 2017 election, this time apparently 3 overhang mandates without compensation are allowed again.... weird compromise to reduce the size a little bit. Anyways, ignoring the new 3 overhang, the procedure is basically complicated mess of rules -->> determines -->> total number of seats total number of seats and federal election results -->> use Webster -->> seats per party seats for one party and votes for that party partitioned by state -->> use Webster (modified, respecting lower bounds for direct mandates) -->> seats of that party for each state seats for one party in one state -->> hand out direct mandates, subtract to determine remaining number of seats -->> use party list in that state to fill the remaining seats
@@steffahn but aren't our complicated messes of rules still producing an essentially unconstitutional result. Thats the whole point I was making was that I don't know a solution that would be compatible with our constituition. And all bill so far introduced can't find one either.
It almost sounds like the problem is that lawyers (who draft legislation and constitutions/basic laws) and judges don't usually understand math... Unfortunately, when constitutional law conflicts with mathematical reality, the latter inevitably wins... (That said, I'm a bit surprised that the German system - which already adds an indeterminate number of "extra" seats every time doesn't just keep on adding extra seats (by Land and overall) until each Land's share corresponds to the "correct" share within some presumably small allowable margin of error. I understand that there is a limit to the number of representatives that you can accommodate in the Bundestag, but unless a maximum number is specified in the Basic Law, requiring a US-style "least-deviation" approach of some kind, it seems to me that the Constitutional Court needs to brush up on their math skills...)

I originally thought the same, but then noticed that when DJ value changed the relative POP/DJ changed accordingly and rounddown() correctly displayed the right value. Point is, the whole POP/DJ column at the very beginning appears to have been divided by a complete different value of DJ (POP/DJ and POP/D values should have been pretty close, as DJ and D were almost identical). To be precise, 880 instead of 930 shown on screen.
I've recently gone from floor level warehousing/logistics to a more administrative role and I've been stunned by what I've found. Where you can face disciplinary action(depending on the company) for a minor mistake when you are handling the products and maybe cost the company tens of dollars, the number of transposing errors in documentation at the administrative level is absolutely appalling and can regularly cost a company thousands of dollars, or even hundreds of thousands depending on the company and specific issue. You can loose an entire order because someone between purchasing at your company, sales at the other company, data input, resource allocation, production runs, packaging, warehousing, shipping, to a carrier's receiving, warehousing and shipping transposes or drops 1 number. Or worse, someone gets a little happy with copy and paste and repeats a number
Don't talk about that to me, i work programming software so to automate, validate, give a nice UI,, etc for that kind of stuff, i work programming an ERP basically and let me tell you, sometimes bussiness flows are so illogical, and wild that they are just not programmable, like they have definitions that can be interpreted differently, and each department actually interprets it differently so no matter the implementation, i will always have some departments call to say that is not how they do it. Or even worse, workflows that directly do not have sense, and the CEO did not realize they did not make sense until i pointed out that logically you can't represent a flow to that, and that what they have been doing until now is just do what their own illogical bussness flow wrong, because it is impossible to do it right, at least when this happens i got a call after a week or so with a revised flow that makes sense, and i have to just code that, but when it is one that has multiple interpretations and each part does it differently oh boy, those i know are here to stay, because nobody will admit that the way they do it is the "wrong" way. And the companies i get to work with are already in the "sane" category, because our boss will not get clients with too wild bussiness flows because we would operate at a loss with them. My favourite is when their bussness flows where actually widely illegal and not even on porpouse. The problem i think, is that management is just that hard, if they fired people for that, they would not have employees, very few people is actually competent at managerial roles, and there are way more demand for those roles than adecuate people, so the bar has to be a little bit low, or you would be firing and hiring constantly.
This video seems to misstate the Balinski-Young theorem. There *is* an apportionment method that avoids both the Alabama Paradox and quota violations. (In short: dole out seats according to critical divisors as you would in Jefferson's method, but skip over a state if it would exceed its upper quota. For more details, see theorem 2 of "A New Method for Congressional Apportionment" by Balinski and Young.) Instead, the Balinski-Young theorem states that if a method follows the quota rule, it exhibits the *population paradox*: it's possible for state A to gain population and lose a seat at the same time that state B loses population and gains a seat.
Balinski-Young theorem seems to state that no method of apportionment can at the same time avoid violations of the quota rule, Alabama paradox and the population paradox. I'm not sure but there might be a method of apportionment that satisfies the quota rule and the population paradox but violates the Alabama paradox.
Huh, I've always heard it as just stating that no method avoids quota violations and the population paradox, and the proof I'm familiar with doesn't require assuming anything about the Alabama paradox.
@@aDifferentJT Here's an example where Hamilton exhibits the population paradox, with three states and 10 seats: First census: populations 1.45M, 3.4M, 5.15M, total 10M, so quotas are 1.45, 3.4, 5.15. Hamilton yields (2, 3, 5). Second census: populations 1.47M, 3.38M, 4.65M, total 9.5M, so quotas are 1.55, 3.56, 4.89. Hamilton yields (1, 4, 5). The first state gained population and lost a seat, while the second lost population and gained a seat.
Huntington-Hill can be described the same way you've described Jefferson, Adams, and Webster. Just like those, you vary and divisor and round. Just like those three round down, up, and linearly, Huntington-Hill rounds using geometric rounding. This means, instead of rounding to the number it is closest to, round to the number which the ratio between the "actual" and "rounded" number is as close to 1 as possible. You can also consider that, for each pair of integers, there is a number between them that separates numbers that round up and down. For linear rounding, that number is always 0.5 above the lower number. For geometric rounding, that number is the square root of the two neighboring integers multiplied (aka the geometric mean). All of these, and the way you described it, give the same results and can be proven to do so.
Something to point out, the House of Representatives has had it's members capped for over 100 years. This means that no more errors can be created from increasing the size of the House, and therefore an error created by increasing the number of available seats is not going to happen at all.
Yes - and I also submit that when the framers of the constitution put in the bit about "no more than 1 rep per 30,000 population" they seem to have also intended to add a House seat for every 30,000 increase in total population. Perhaps this never happened as intended?? Obviously, the cap became necessary as the population grew (for example - based upon todays population 329,000,000 / 30,000 = 10,967 (yikes!) seats in the House). How the "1 rep per 30,000 in population" clause made it thru the drafts into the final Constitution is undoubtedly a story in itself, and I suspect that Washington (possibly Jefferson as well) were personally invested in keeping the clause intact. Thus the Washington veto of the Hamilton plan. If Washington was under the impression that the number of house seats in future were to be added using the 1 per 30k in population, his veto makes slightly more sense as most of these paradoxes and complexity may disappear.
Yep. Statehood to Puerto Rico and DC would actually _decrease_ the size of the House, since those two currently have non-voting members and those would be replaced with one or more of the 435 voting seats.
@@cr250rdr I will say there is still an attempt to follow the 1 per 30k Rule... Not only are there 435 Representatives at a Federal level, but there are also 5411 Representatives at a State Level... So 5,846 out of 10,967 is only half way there, but the disparity isn't as severe as it appears. Altho the biggest problematic states that are severely under the 30k requirement are the 4 highest population states, California, Texas, Florida, and New York who have a total of only 500 representatives against 111m pop... Actually if you remove those states from the figures... 329 - 111 = 218, 5411 - 500 = 4911... 218m/4911 = 44,390 or if we also add in Federal 218m/5203 = 41898... Eh, we are still quite a ways off, but yea... I can kinda understand why the seat limit, and why these big states want to limit how many state seats they offer too... I guess we just need to divide the big states too
Given our willingness to accept 3 significant figures in the percentages we represent the portion of the population with, we could just lock it at 1000 and solve all of these problems, unless a state happens to fall below .01% pop Now, that would give California almost 1200 districts and I'm not sure the best way to handle that, but at least on paper, the number of representatives would not be part of the problem that needs to be solved.
One fix is to use non-integer representation. Use one of these methods to determine the number of seats, but each representative doesn’t get exactly 1 vote. They get the precise fraction that, summed with the other representatives of the state, would give the state exactly the decimal percentage they should get.
@@hungrycrab3297 that is a fantastic idea. Japan has pretended to try and fix its imbalance that favours rural districts, by making some of the small prefectures share one representative. Using your idea, each prefecture could still have one guy in parliament (it’s always a guy in Japan), but e.g. Tottori’s rep would only have 0.44 of a vote. That is surely the fairest way to do it. On the other hand, if a state should have 2.7 votes, then they get 3 reps, each worth 0.9 of a vote
yes, this is what I came here to say. It’s fine to round to an integer number of representatives but then they each contribute the exact fraction of a vote. Or another way of saying it, each state contributes their integer votes times the % of that state’s population to the total. Then rounding essentially has no impact. (well it only affects the granularity of the votes).
@@snivesz32 Yep exactly. And let’s combine that with multi-member districts, giving each representative the proportion of votes they actually received, and I think I’d actually like the system.
@@hungrycrab3297 And to add insult to an injury, let them earn 0.23423 fraction of the wages also. National laughing stock would be the guy with 0.0072
Am I missing something here or is this entire problem due to an arbitrary total number of seats to be allocated? Surely the fairest system would be a fixed quota, normal rounding and having however many seats that adds up to?
Well, yes, that's a dependency of the problem. There are practical reasons to limit the number of representatives. Maybe less so in the information age however...
Absolutely, but it'd cause inflation issues. The more representatives there are, the less each one matters, but the less there are the more people that are represented by one vote (which is a negative). The goal is to ensure that each vote represents a correct amount of people without devaluing any singular vote.
@@TrueFlameslinger I don't remember the entire context here given I watched it a month ago, but my suggestion was based on precisely the opposite of what you state. I suggested that rather than work from a fixed number of seats down, it should be a fixed number of people represented by each representative adding up to however many seats that adds up to, there would have to be some amount of rounding given voting districts are per state but the only increase in the number of representatives would be correlated with population size which negates dilution of representation rather than create it as you suggest.
@@badgerfool1980 You could even adjust the number of people per seats for every election to make the total number of seats come to as close as possible to some desired value.
This is awesome, I have looked into this the past 2 months, and it was great at throwing me back to the big picture, and looking at the fundamentals, instead of getting stuck in 3d models covered in dots, that each represents a seat. If I had seen this 2 months ago, you would probably have saved me a month of free time research. This video is great for anyone curious about this.
At 16:55, 24.8614 gets rounded down to 23 and 11.0375 gets rounded down to 10. What's that about? Shouldn't they be 24 and 11 respectively? Also, later, those numbers decrease but he says that they increase. Am I missing something?
Throughout this video I was waiting for a reference to the D'Hondt method, and it would have been interesting to have seen it mentioned (as it is used in many countries). What I didn't know, and only discovered because this video prompted to read more about it, is that D'Hondt method is equivalent to the Jefferson method, although the two look different.
I actually don't think there is an issue with rounding large numbers up by more than one, the system should be based logarithmically and thus 22.5 is closer to 24 than 1.5 is to 2
Concentrating power based off the power a state already has could increase corruption. However I don't confidently back favoring smaller or larger, I think both sides have good arguments.
@@bkm8556 I think my personal ideal would be to round normally, if you over shoot by rounding up too much increase the divisor until you have the correct number, if you under shoot reduce the divisor until you have the correct number. This avoids the larger states getting a consistent advantage from always rounding down and the smaller states getting an advantage from always rounding up to make a genuinely fair system, my original point was simply that I don't think its unfair if something is rounded by more than 1

In a legislature, one way to sidestep this might be to have variable voting powers depending on your share of state population. E.g. you still need to go through the maths to get the number of legislators, but when they cast their vote on a bill, they don't cast 1 vote -- they cast ROUND(X/N) votes where X=their state's population, and N=number of legislators the state has.
@@Excalibaard hah, indeed. And I guess that means different productions might include all this or not? So if anyone disagrees with Lottie here, they must just be familiar with a different production. Still, I think Mr. Parker should find out directly!
I instinctively think what's more important is how much error each state has rather than the Alabama paradox or the quota rule. That is, I think we should allocate seats to whichever state has the highest error error is their actual seat divisor. I _think_ this is very similar to what the Hill method is doing but maybe the squaring helps with small vs. large states.
Is it the case that giving a seat based on minimizing an individual states error that the total error of all states could increase, and if so is that an issue? Probably an individual states error is a bigger deal than the accumulative but I dunno
Yes I was thinking the same, drop everything except allocating seats in such a way as to bring each divisor to as close as possible to each other while being able to adjust the number of seats based on a specific constraint. I.e say if every census period you could add or remove up to 5 seats either way, this combined with a method that minimizes disparities would probably yield the most equal result.
Another simple improvement is to remember the rounding from each election and add them back before apportionment for the next election takes place. So, with two states with 1501 and 1499 inhabitants and a total of three seats, each state would generally alternate between having 1 and 2 representatives.
I would like to say that this video has used the word Vermont more times than I have ever heard used on RUclips since I have started watching. I have lived within the state of Vermont all that time and would like to thank you Matt for the internet noise.
I'm really glad the Hill method is the one they currently use. It was the first thing I thought of as a solution, since if you do it step by step you don't get any 'this feels unintuitive' steps.
At 4:59, I believe he said '93.2' when he meant to say '932', as that is what he puts on screen at the same time, and that matches the calculation done.
I was thinking "why not do the Jefferson method, but cap the allocation so it never violates quota" and that is exactly a real thing, called a quota-capped divisor method, and specifically the Balinsky-Young quota method! There can still be issues with these methods too, however
The quota rule doesn't seem intuitive to me? Rounding up and down might result in a different percentage deviation for large and small populations. So rounding up 1.01 to 2 is almost +100%, but rounding 23.01 up to 25 is more like +8%
@@anwyl42 Yeah, exactly, so why does it not make sense to want to minimize the overall number of unrepresented seats? Could you maybe explain why that percentage deviation is so important?
@@ChayaKhy Minimizing maximum percent deviation minimizes the maximum deviation in representation per person. Allowing 100% deviations allows for some people to have double the representation, or worse, no representation. The other metric in the video isn't minimizing underrepresented seats (that could be done by having 0 seats), but instead avoiding a deviation of >1 seat from the number that rounding would allocate. That seems arbitrary to me.
@27:45 Pro-tip when collecting data: take the time to actually read the column headers and footnotes. First PDF for Vermont: Column: Resident Population Footnotes: 1. The resident population excludes the overseas population. 2. Congressional apportionment for each state is based upon (1) the resident population and (2) the overseas U.S. military and federal civilian employees (and their dependents living with them) allocated to their home state, as reported by the employing federal agencies. Second PDF for Vermont: Column name: Apportionment Population The columns are not even reporting the same thing at all, these are two different statistics. The numbers shouldn't be the same: apportionment population and resident population are two different things. Of course, the apportionment population should be *larger* than the resident population, which in these cases they're not, so there's still a mystery there, but the "original source" you presented also says clearly PRELIMINARY at the top in the title, so no you haven't found the original source, just a preliminary draft.
New method: (1) Calculate ideal representation amongst the states and truncate the fractional components. (2) Determine the number of representatives R, by which the house falls short (3) Each state puts forward 1 candidate (4) Thunderdome to the last R candidates
I know it's not really related to methods of apportionment, but I can't help but wonder how the Wyoming Rule would play into all of this: setting the total number of representatives so that the average population per representative in each state is equal to that of the least populous state (currently Wyoming).
That would require a creation of more seats in Congress, which is somehow illegal, despite the fact that it could probably be challenged as damaging states that should have the missing representatives. It would be about 500 more total reps.
The state of New Hampshire has to deal with the same problem when apportioning representatives to the state house of representatives (the number of representatives is high enough that towns are frequently entitled to more than one, and the state constitution prohibits splitting towns into smaller districts). Interestingly, it uses floterial districts (en.wikipedia.org/wiki/Floterial_district), which are very similar to Matt's idea of time sharing a representative, but instead of each selecting a representative for part of the time, multiple areas that are entitled to fractional leftovers are joined to create a second district that floats over a first district. The second district then uses most of the fractional entitlement to representatives. I would love to see him tackle the math of the fairness of that scheme.
6:05 until this point I wasn't sure if you had managed to significantly change the style of an actual excel-like something and were recording your screen or if you were just animating what excel would be like if only it had matt-parker-animation-style cells.
@@shelvacu wish they'd use R1C1 style. That makes so much more sense. instead of $B4/$B$2, you would have RC2/R2C2. The most common kind of references (reference to the same row or same column, or absolute references) don't require special symbols. and the formula would look the exact same in all the cells you pull it down into, much easier.
I have an idea. Instead of making each rep's vote worth 1 after everything is allotted, why not allow the votes to be worth fractional values? For example, a state with 3 reps that should have gotten 3.6, each rep's vote is worth 1.2 instead of 1. This ensures that each state has the right amount of voting weight, with no violations or paradoxes.
You try telling Mississippians that Californian Representatives get more of a vote than them. In all seriousness, mostly because people don't like thinking a Bill passed by one tenth of a vote. Especially if you end up rounding to significant figures or decimal points that people don't like. If a state has a decimal of .345, theyre going to be great proponents of 2sigfig- what I learned in my math classes! A good American rounding! But the closer to 4 the last digit gets without going over, the more likely it is you'll be of the opinion we should do it FAIR, and keep going to figure twelve. A nice American number, twelve. And we don't have to write it all down at the end, we can round then, we just need it for accurate calculations in the middle bit. But the real problem is you don't have a time machine. This solution would be so unbelievably unintuitive that it could only be set up by people already setting up a political system 'from scratch' (yeah, total coincidence you've got a bicameral legislature with one appointed and one elected house. mhm). It's annoying to hear "this won't happen because people don't think it can happen, but, well... Maybe you'd have more luck implementing it in local Government?
Legal fictions are incompatible with justice. If the representation was meaningful this sort of problem wouldn't come up. If jurisdictions were meaningful likewise.
I believe this idea was actually proposed in Congress some time ago, but I couldn't find who or when... I believe it was in the '80s or '90s by Rep. Norton (Delegate for District of Columbia) but I may be wrong on both counts.

You start to explore at the end, "What if partial representatives existed?". Why not go all the way and give each state a given # of representatives exactly apportioned to population and let the states divide those representatives however they wish. ie if the divisor is 40,000 and the state has 110,000, then they would receive 2.75 reps that they could send, either 1 rep with 2.75 votes, 2 reps with 1.375 each or why not let them do 1 rep with 1.7 votes and another with 1.05? (maybe they wanted to allocate their reps voting power in exact proportion to the votes received in the election) There would be a need for meta rules potentially Some potential examples: Each rep sent must have at least 1 vote, Each rep sent may not have more than n votes (2 being the obvious #, although this isn't as needed as the former, if a state wants a mega rep, why not let them?) This would open the possiblity for states to do away with districts (yay, gerrymandering gone, although states would still exist) and just allocate their reps based on votes received in one large election. Yes house voting would get more complex, but technology has advanced somewhat since the late 1700s. Also if states held statewide elections, I'd expect 3rd parties to start earning more seats (only need 2% of CA voters to get a seat with > 1 vote, bet Green could get at least one, etc). Although this last comment is likely why no major parties would ever decide to do it as it would have the potential undermine the party slowly or fracture into interest groups rather than a party.
What a refreshing veto, too. "I'm not signing this because I don't think it's Constitutional." Compare with present day "I'm signing this executive order even though the Supreme Court will probably strike it down. Because it'll take them a couple months to do so, and in the meantime we can enjoy my awesome if unconstitutional policy."
40:46 Ack, a Tie?!? That's the WORST possible outcome. To explain: If there is a tie, then the top two candidates (the ones who tied) are put in a run-off election in the US House of Representatives. HOWEVER, it is not 'each representative gets a vote' which would be 'roughly' proportional to the population (we just saw how it's never correctly proportional), id is 'each STATE gets a vote,' with no clear indicator of how the representatives for a state choose what their 'one vote' will be; they could co 'majority rule,' they could debate until they reach a consensus, or a senior representative could bully the junior representatives to agree to him being the one with the choice. 'Voting by rep' favors the larger states, which seems logical as those are the states with larger numbers of Electors, 'voting by state' GREATLY favors the smaller states, as Rhode Island's vote can completely cancel out California's vote.
Love this! My first thought, early in the video, was effectively to normalise before ranking the fractions. If I weren't ADHD, I'd be setting that up in a spreadsheet right now -- but I have so many other things to procrastinate on! :D

On initially hearing it, I like his proposed buddy system for states rounding to half a representative because it could encourage more cooperation and understanding in this time where many people seem bound and determined to villainize the "other side" in their heads. 16:37 somehow the divisor Jeff isn't correct in this particular instance, those numbers are the result of dividing the populations by 880 rather than by 930. The rounding still ended up rounding as if the numbers had been divided by 930, just the numbers for =pop/DJ are using DJ=880. Not trying to bash or hate, just pointing out in case anyone else was looking at those numbers wondering why 24.86 rounds to 23 and happens to look at the comments to see this.

Hey Matt, I wonder: haven't you considered using closed captions for your videos, even autogenerated ones? It could really enhance the viewing experience.
I have to agree with Stan, they make a huge difference. I usually watch videos in high ambient noise conditions and it makes some videos unwatchable. Not this one though, the volume isn't terrible and you enunciate well. Unfortunately it seems to make the closed captioning reliable and accurate creators need to make them rather than using the auto-generated ones. I've seen this same problem elsewhere. Or the auto-CC are terrible, my Pixel 5's auto generated CC will be more accurate. But those start lagging farther and farther behind very rapidly...

Fun fact, the folks at Wikipedia have actually gone through the research and found that the original census actually miscounted a single county that had 450 people living in it.
So, it actually isn't a transpose error where somebody flipped a digit.
The original source is off by 450, and it happens by coincidence that 490 + 450 = 940.
How wild.
It's possible that their "miscounting"... was flipping the digits. You don't accidentally count an extra 450 people. You miswrite something.
@@JoCE2305 I agree with you. A transcription at some point is far more likely.
The transcription may well have occurred at a more local level and the difference would be carried forward in the total.
BTW, any transposition (reversal) of two sequential digits in a number will yield a difference that is a multiple of "9".
So the original mistake (if it was a transcription error ) could have occurred by using 160 in place of 610 (which again has a difference of 450) or any of several other number pairs.
[ in book-keeping, back before spreadsheets addition was often checked by doing it twice. If two sums were off by some amount that was a multiple of 9 it was always a good practice to look for a transposition error between the two sets of numbers ]

At 16:33, you've claimed that POP(New Triangle) / D_Jeff(930) = 24.8614, rather than the correct ~23.5247. Notably, in your next column, you've fixed the issue with the rounding down correctly recommending 23 seats, but it's still a very baffling error if you don't get out a calculator and do the division yourself.
The error also carries over for Circula, where you've listed the incorrect value of 11.0375 rather than the correct 10.4441, though your floor function still works.
Actually, looking a little closer, that whole column appears to be in error, as though you used a divisor other than 930. It's simply that New Triangle and Circula end up being off by a whole seat, so when you fix the equation in the next column that also takes the floor of each number, it's readily apparent for them.
so glad you said this, thought i was going crazy... why is that 24 rounding down to 23?? oh because it wasn't supposed to be a 24.
I guess the devisor used was 931 instead of 930 but the issue there would have been that the total number of seats after rounding down would add up to the required 43 making the next part of the video obsolete.

This reminds me of a similar problem I ran into when writing an RPG engine back in high school (circa 2003 I believe). I was treating character level as a percentage scalar to total attribute values but wanted to distribute attribute increases consistently at every level, so rather than do each attribute individually I decided to increase the total attribute pool itself, then distribute that pool proportional to each attribute's base value. So, for instance, the initial pool was 20 points per character with a 20% increase per level, meaning I wanted 4 new attributes to be automatically distributed with each level up.
The problem I quickly ran into was that using the Hamilton method (without knowing that's what it was; it was just the first solution I stumbled upon), was that the 20% increases led to beat frequencies where occasionally the fourth and fifth highest remainders could be **ties** from attributes with identical bases, meaning no exactly-4 increase was possible with that method. In the end I just scrapped it for a round-down approach that had increment spikes on the beat frequencies, since I felt having every 5th level be the one where **every** attribute increases made for a better RPG style "milestone" feel anyhow.
Or the fact that every data science library divides trust data up using Hamiltons method that every program discovers and is used for non political scientific research

A very similar problem comes up in typesetting when splitting lines evenly into a paragraph. A native solution tries to minimise the total divergence of spaces between words from the average, but that can result in one line being very bad (for example, two words on the line with a massive space between them) while all the others are okay. The fix is to minimise the average of the squares of the divergence; I believe that’s what Don Knuth’s TeX system does (I worked with it back in the 90s, so forgive me if my recall is bad). There are also strange Alabama-like paradoxes caused by the fact that although spaces can be stretched and shrunk smoothly, words do not normally stretch or shrink and jump from one line to another unpredictably as wrap width changes or new text is inserted. I spent a happy but confusing 9 years working on typesetting software and have scars to prove it.
It's always interesting when the same mathematical problem has repercussions in such different fields.
This is why justifying a table of contents is my least favorite and most time consuming part of writing any paper. Why don't all the lines end at the right margin? Why are all my numbers misaligned? Why isn't each character "space" the same width, or each line the same number of spaces?

The problem, of course, is integer representatives. But you don’t have to solve that issue by chopping up representatives, instead you could fractionalise the power of their vote to match the size of their representation.
This then causes problems with voting because the votes are no longer equal, but it could be argued that’s the only way to be truly fair with integer representation.

That whole problem stems from trying to squeeze between 2 rigid rules: divisor & max seats. If we left the divisor uniform & the max seats flexible, it works fine.
In the beginning, the divisor was 30,000.
The populations round naturally up or down, except when the result is
That's the downside of having to actually fit these people in a physical location.
If we'd actually used the original uniform divisor of 30,000 we'd currently be at about 10983 seats, which puts us into stadium territory at a minimum. Per Wikipedia, all NCAA FBS college football stadiums except for one in Hawaii would hold it, but only 77 out of 360 NCAA Division I basketball stadiums could hold that house of representatives.
Considering the US Capitol building was designed in 1792, they didn't foresee the growth the country would experience. Beyond that, a full stadium complex behind the capitol building might ruin the view for those looking at the Mall.
@@MrSJPowell
Thus as population grows, the divisor has changed: 50,000 then 75,000 then 100,000 to ~750,000 today. That's what I'm saying SHOULD be flexible. If the max seats is 435 (as current), adjust the divisor until the natural rounding gets you as close to 435 as possible without going over.
The paradox comes in w seat 435 when it naturally lands at 434. There is NO extra seat, just leave it at 434.
Actually, I was thinking just that. What if the rules allowed also the addition/subtraction of seats based on the proximity of divisor to the last allocated seats? Pretty much what you said (but I thought allow going over in case going under falls too short): Start with 435 targeted seats and allocate an actual number between 434-436 based on the outcome.
@@IHateUniqueUsernames
I agree it could fall into a range of values, but physical limitations would produce a hard upper limit. I am also wondering how to handle the excessively high divisor issue. 750,000:1 seems a bit excessive to me.

Considering the current state of the country, I doubt such a split would be amicable. However, if it had been planned for a split from the beginning, it might have worked better. We almost had it in the 1860s w/o planning.
Your idea mirrored my original thought: geographic regional governments between state & federal. The main problem is checks & balances between regional vs federal vs state. If the House alone was regional, it would effectively split the House into x separate Houses. Any bill would need to pass all x to pass the House. W 11,000 reps, legislation would effectively STOP being passed. (Not that that would always be a bad thing.) But it would be of little difference than running the bill by each state house individually. Reconciliation would take forever.
I still find it funny that all these methods have different names in different places. In Germany the Hamilton method is called Hare-Niemeyer, Jefferson is called D’Hondt, and Webster is called Sainte-Laguë.
Another interesting thing to look at I think is, what if we don't require an exact number of representatives. What if we just use that number as a target number and if it deviates slightly after rounding (up/down/closest integer) we just have a few empty or extra seats until the next census?
Or, we just remove bits from the fractional representative? I suppose then the problem is, is that you'd need to do a proportional lobotomy but that has the risk of making the representatives more effective.
Or you could just let the representative cast a vote equal to the population of their district.

Quite frankly: too many people.

In Australia the number of MPs is supposed to be *approximately* twice the number of senators - it's important to maintain a consistent ratio for the case of a joint sitting.

Honestly, the issue of representatives is a *TINY* one compared to the problem of the senate, in which 50 senators--potentially representing the 25 smallest states--potentially with the least educated populaces, can bring the entire legislative process to a grinding halt, which is what we see right now.
Democracy has an inherent fatal flaw--in that it gives one vote to one person, regardless of how intelligent that person is. That is, if you had a disease, would you value the opinion of 50 Google MDs, or one actual medical specialist?

Which is why past a certain point adding representatives is meaningless, as in the end political groups like parties end up having to make the actual decisions so that what actually matters is the fraction of the chamber each group controls rather than the opinions of most individual representatives.
But that requires Americans to be smart and the Republican voter base would be too lost
Did I miss the part where it's explained *why* apportionment systems have to either break the quota rule or have "Alabama paradoxes"? Where can I go to find the proof that no algorithm can avoid both kinds of unfairness?
I was curious about this too and found something called the "Balinski-Young Theorem". It includes a "population paradox" in addition to the Alabama paradox. In the population paradox a small state with rapid growth can lose a representative to a large state with slower growth. According to the Balinski-Young theorem it IS possible to create a method that follows the quota rule and doesn't have an Alabama paradox but it will have a population paradox. A method can avoid the population paradox and the Alabama paradox but then it will have issues with the quota rule for certain values. I'm no mathematician so I can't explain the proof but it certainly is interesting. en.wikipedia.org/wiki/Apportionment_paradox#Balinski%E2%80%93Young_theorem
@@dking7120 Thanks a lot, I was really wondering about that!

@@masterplusmargarita yes, especially as the title of the video is "why it's mathematically impossible...". It seemed more like just listing problems with some methods with no actual reasoning why it's impossible in general.
You must have missed it, because he definitely showed the proof, and he explained it, very thoroughly. He even wrote a song about it, to make it easier for kids to remember, and he paid Tom Brady and Lebron James to sing it together, along with some old man dressed up like Santa Clause, and Big Bird from Sesame Street. I don’t know how you could’ve missed that. There might be something wrong with your Internet, but I bet you just weren’t paying close enough attention. Try reloading the video, and then watch it again at 0.5 speed. If that doesn’t work, then you might have to upgrade to RUclips Premium, and eat some wild mushrooms like I did. Good luck.
The basic reasoning is that when you use the quota rule, you’re left with a bunch of fractions of seats that you must round with.
The 1 tenth decimal place value is completely independent and not causally related to the whole number of seats a state is allocated, and it is also the way the remaining seats are allocated.
So the subsequent rounding ends up giving out a bunch of arbitrary or “unearned” seats to states. Since these unearned seats are almost randomly given out, increasing the total number of seats can randomly take them away as well. So you end up with the Alabama paradox.
It isn’t really a paradox though. We only think it’s unfair to lose a seat because we assumed the original allocation was fair in first place. In reality, Alabama just loses the random advantage that gave it a seat it didn’t necessarily ‘deserve’ in the first place.
Yes you can have a system that obeys both: you just vary the total number of seats. The problem is having a fixed number of total seats instead of just assigning seats proportionally without an upper or lower limit. Why do you need 299 total seats? Just have seats equal to the number that is most accurately representing the population proportion! If that means one census you have 300, fine, if the next is 298, also fine - as long as the partitions are properly represented in percentage.
As math system it would work. But as a real life situation with constitution changes and other juridical details as well as persons who benefit from how the current system works - it would never happen.
@@thebomber7641 Come on, what could possibly go wrong with a House of Reps with 11,124 seats?
@@thebomber7641 Germany do this (a bit different how it is done, but they do change the number of seats) ^^
The problem with this method is, if done, the states then have to follow a similar system of division... which is often politically gerrymandered to favor a particular political party (both of the American political parties are guilty, just depends on the state in question). So, every 10 years, every state would then have to (get a chance to) redo their house district maps for federal representation.
Ultimately, the likely best solution (since the USA is and likely will remain a two party country for the foreseeable future) is to leave the Senate with 2 seats per state. The House converts to proportional representation based upon the political parties. (Like many European nations.) This... will likely never happen, though.
@@terr281 Would you take me through your reasoning again? I fail to see why a variable number of delegates (according to a fixed "1 delegate per every x-thousand state inhabitants" formula) would increase gerrymandering problems, or how the specific method used to determine the number of delegates/districts should positively or negatively influence gerrymanderbility.

I had to deal with this when splitting tips between people at a pizza place. Dividing total tips by total hours worked and then multiplying individual hours worked to find how much they earned. Most of the time, the rounding was easy and fair but every so often, we had to give out more tips than we brought in due to rounding. Luckily, I just took money from managers first (I was one, don't worry) and it usually worked out.
It's illegal under federal law for owners, managers, and supervisors to participate in a tipping pool at all, even if they provide direct table service, so I'm still a bit worried...

Hi Matt,
I just watched this very entertaining Video and I'm from Germany! Over the last 15 years we had a very strong debate about how to allocate our seats in the Parliament proprtionally to voters. At this point we had 3 different aproaches all passed into law then later being anulled by the constitutional Court for not being fair enough. I thought you could weigh in and explain why its so difficult to figure it out fairly.
Here are some fun facts about the german system that make the maths so difficult:
- Germany is divided into 299 little parts and each of them elects one member 1st past the post (simple) we call that the "Die Erstimme"
- after that we take another 299 Seats and use them to rebalance the Parliament so that every party gets representation roughly equal to their amount of voters. We call that the "Zweitstimme".
- the complication to the second rule is that we do that rebalancing not for whole country at once but for each of the 16 federal states individually. this leads to the problem that the bigger party's get more first past the post seats than they should get even in the full 598 strong house after rebalancing. So tjose bigger partys just get these on top of the 598 which leads to us having more seats overall. we camm the Überhangmandate
- Now that the Parliament has more seats the Divisor changes (YAY!!!) which leads to all parties getting more seats we put the on top again we call "Zusatzmandate"
- After all of that the bigger parties still come out unfairly ahead so we put in even more seats this time only for parties that didn't get any "Überhangmandate" we call these extra seats "Ausgleichsmandate"
In the End we have between 603 (2002) and 736 (2021) but depending on the votes it could even go past 900
Have fun getting all this mess organized maybe you can find a solution. At the Time of me writing this we haven't had a constituionally valid Voting legislation for more then 15 years!
These considerations are mostly independent from the basic method used to turn percentages into number of seats. For that, we currently use Webster's method (i.e. using a divisor and "ordinary" rounding). Webster's method is also used a second time, to further split up each party's seats among the 16 states, according to the number of votes in each state. Also there's no state-level "rebalancing" as you described; the total number of seats for a party only uses the federal result. "Überhangmandate"+"Ausgleichmandate" actually just operate by increasing the size of parliament first, then doing an ordinary round of Webster's method; and the size of parliament was chosen do accommodate for all the direct mandates (in a somewhat complicated manner that does take individual states into account). Well that was how it worked until 2017 election, this time apparently 3 overhang mandates without compensation are allowed again.... weird compromise to reduce the size a little bit.
Anyways, ignoring the new 3 overhang, the procedure is basically
complicated mess of rules -->> determines -->> total number of seats
total number of seats and federal election results -->> use Webster -->> seats per party
seats for one party and votes for that party partitioned by state -->> use Webster (modified, respecting lower bounds for direct mandates) -->> seats of that party for each state
seats for one party in one state -->> hand out direct mandates, subtract to determine remaining number of seats -->> use party list in that state to fill the remaining seats
@@steffahn but aren't our complicated messes of rules still producing an essentially unconstitutional result.
Thats the whole point I was making was that I don't know a solution that would be compatible with our constituition. And all bill so far introduced can't find one either.
It almost sounds like the problem is that lawyers (who draft legislation and constitutions/basic laws) and judges don't usually understand math...
Unfortunately, when constitutional law conflicts with mathematical reality, the latter inevitably wins...
(That said, I'm a bit surprised that the German system - which already adds an indeterminate number of "extra" seats every time doesn't just keep on adding extra seats (by Land and overall) until each Land's share corresponds to the "correct" share within some presumably small allowable margin of error. I understand that there is a limit to the number of representatives that you can accommodate in the Bundestag, but unless a maximum number is specified in the Basic Law, requiring a US-style "least-deviation" approach of some kind, it seems to me that the Constitutional Court needs to brush up on their math skills...)

I originally thought the same, but then noticed that when DJ value changed the relative POP/DJ changed accordingly and rounddown() correctly displayed the right value.
Point is, the whole POP/DJ column at the very beginning appears to have been divided by a complete different value of DJ (POP/DJ and POP/D values should have been pretty close, as DJ and D were almost identical). To be precise, 880 instead of 930 shown on screen.

I've recently gone from floor level warehousing/logistics to a more administrative role and I've been stunned by what I've found.
Where you can face disciplinary action(depending on the company) for a minor mistake when you are handling the products and maybe cost the company tens of dollars, the number of transposing errors in documentation at the administrative level is absolutely appalling and can regularly cost a company thousands of dollars, or even hundreds of thousands depending on the company and specific issue.
You can loose an entire order because someone between purchasing at your company, sales at the other company, data input, resource allocation, production runs, packaging, warehousing, shipping, to a carrier's receiving, warehousing and shipping transposes or drops 1 number. Or worse, someone gets a little happy with copy and paste and repeats a number
Don't talk about that to me, i work programming software so to automate, validate, give a nice UI,, etc for that kind of stuff, i work programming an ERP basically and let me tell you, sometimes bussiness flows are so illogical, and wild that they are just not programmable, like they have definitions that can be interpreted differently, and each department actually interprets it differently so no matter the implementation, i will always have some departments call to say that is not how they do it. Or even worse, workflows that directly do not have sense, and the CEO did not realize they did not make sense until i pointed out that logically you can't represent a flow to that, and that what they have been doing until now is just do what their own illogical bussness flow wrong, because it is impossible to do it right, at least when this happens i got a call after a week or so with a revised flow that makes sense, and i have to just code that, but when it is one that has multiple interpretations and each part does it differently oh boy, those i know are here to stay, because nobody will admit that the way they do it is the "wrong" way.
And the companies i get to work with are already in the "sane" category, because our boss will not get clients with too wild bussiness flows because we would operate at a loss with them.
My favourite is when their bussness flows where actually widely illegal and not even on porpouse.
The problem i think, is that management is just that hard, if they fired people for that, they would not have employees, very few people is actually competent at managerial roles, and there are way more demand for those roles than adecuate people, so the bar has to be a little bit low, or you would be firing and hiring constantly.
So how do people train people to be good at manegerial roles, or at least specific parts like accounting and bookkeeping?
This video seems to misstate the Balinski-Young theorem. There *is* an apportionment method that avoids both the Alabama Paradox and quota violations. (In short: dole out seats according to critical divisors as you would in Jefferson's method, but skip over a state if it would exceed its upper quota. For more details, see theorem 2 of "A New Method for Congressional Apportionment" by Balinski and Young.)
Instead, the Balinski-Young theorem states that if a method follows the quota rule, it exhibits the *population paradox*: it's possible for state A to gain population and lose a seat at the same time that state B loses population and gains a seat.
Balinski-Young theorem seems to state that no method of apportionment can at the same time avoid violations of the quota rule, Alabama paradox and the population paradox. I'm not sure but there might be a method of apportionment that satisfies the quota rule and the population paradox but violates the Alabama paradox.
Huh, I've always heard it as just stating that no method avoids quota violations and the population paradox, and the proof I'm familiar with doesn't require assuming anything about the Alabama paradox.
@@jonahostroff I may be missing something but I don’t think Hamilton’s method suffers from either quota rule violations or the population paradox.
@@aDifferentJT Here's an example where Hamilton exhibits the population paradox, with three states and 10 seats:
First census: populations 1.45M, 3.4M, 5.15M, total 10M, so quotas are 1.45, 3.4, 5.15. Hamilton yields (2, 3, 5).
Second census: populations 1.47M, 3.38M, 4.65M, total 9.5M, so quotas are 1.55, 3.56, 4.89. Hamilton yields (1, 4, 5).
The first state gained population and lost a seat, while the second lost population and gained a seat.
@@jonahostroff nice, you just squashed Johnny boy with that simple counter example
Huntington-Hill can be described the same way you've described Jefferson, Adams, and Webster. Just like those, you vary and divisor and round. Just like those three round down, up, and linearly, Huntington-Hill rounds using geometric rounding.
This means, instead of rounding to the number it is closest to, round to the number which the ratio between the "actual" and "rounded" number is as close to 1 as possible. You can also consider that, for each pair of integers, there is a number between them that separates numbers that round up and down. For linear rounding, that number is always 0.5 above the lower number. For geometric rounding, that number is the square root of the two neighboring integers multiplied (aka the geometric mean). All of these, and the way you described it, give the same results and can be proven to do so.
Thanks, good to know!
If you ever see someone on a bench talking to themselves in an agitated way, they are likely a data analyst
Something to point out, the House of Representatives has had it's members capped for over 100 years. This means that no more errors can be created from increasing the size of the House, and therefore an error created by increasing the number of available seats is not going to happen at all.
Yes - and I also submit that when the framers of the constitution put in the bit about "no more than 1 rep per 30,000 population" they seem to have also intended to add a House seat for every 30,000 increase in total population. Perhaps this never happened as intended?? Obviously, the cap became necessary as the population grew (for example - based upon todays population 329,000,000 / 30,000 = 10,967 (yikes!) seats in the House). How the "1 rep per 30,000 in population" clause made it thru the drafts into the final Constitution is undoubtedly a story in itself, and I suspect that Washington (possibly Jefferson as well) were personally invested in keeping the clause intact. Thus the Washington veto of the Hamilton plan. If Washington was under the impression that the number of house seats in future were to be added using the 1 per 30k in population, his veto makes slightly more sense as most of these paradoxes and complexity may disappear.
The error still exists though. If your state would have received an extra rep if the house had 434 seats I don't think you would be very happy
Yep. Statehood to Puerto Rico and DC would actually _decrease_ the size of the House, since those two currently have non-voting members and those would be replaced with one or more of the 435 voting seats.
@@cr250rdr I will say there is still an attempt to follow the 1 per 30k Rule... Not only are there 435 Representatives at a Federal level, but there are also 5411 Representatives at a State Level... So 5,846 out of 10,967 is only half way there, but the disparity isn't as severe as it appears. Altho the biggest problematic states that are severely under the 30k requirement are the 4 highest population states, California, Texas, Florida, and New York who have a total of only 500 representatives against 111m pop...
Actually if you remove those states from the figures... 329 - 111 = 218, 5411 - 500 = 4911... 218m/4911 = 44,390 or if we also add in Federal 218m/5203 = 41898... Eh, we are still quite a ways off, but yea...
I can kinda understand why the seat limit, and why these big states want to limit how many state seats they offer too... I guess we just need to divide the big states too
Given our willingness to accept 3 significant figures in the percentages we represent the portion of the population with, we could just lock it at 1000 and solve all of these problems, unless a state happens to fall below .01% pop
Now, that would give California almost 1200 districts and I'm not sure the best way to handle that, but at least on paper, the number of representatives would not be part of the problem that needs to be solved.
One fix is to use non-integer representation. Use one of these methods to determine the number of seats, but each representative doesn’t get exactly 1 vote. They get the precise fraction that, summed with the other representatives of the state, would give the state exactly the decimal percentage they should get.
@@hungrycrab3297 that is a fantastic idea.
Japan has pretended to try and fix its imbalance that favours rural districts, by making some of the small prefectures share one representative.
Using your idea, each prefecture could still have one guy in parliament (it’s always a guy in Japan), but e.g. Tottori’s rep would only have 0.44 of a vote.
That is surely the fairest way to do it.
On the other hand, if a state should have 2.7 votes, then they get 3 reps, each worth 0.9 of a vote
yes, this is what I came here to say. It’s fine to round to an integer number of representatives but then they each contribute the exact fraction of a vote. Or another way of saying it, each state contributes their integer votes times the % of that state’s population to the total. Then rounding essentially has no impact. (well it only affects the granularity of the votes).

Well, yes, that's a dependency of the problem. There are practical reasons to limit the number of representatives. Maybe less so in the information age however...
Absolutely, but it'd cause inflation issues. The more representatives there are, the less each one matters, but the less there are the more people that are represented by one vote (which is a negative). The goal is to ensure that each vote represents a correct amount of people without devaluing any singular vote.
@@TrueFlameslinger I don't remember the entire context here given I watched it a month ago, but my suggestion was based on precisely the opposite of what you state. I suggested that rather than work from a fixed number of seats down, it should be a fixed number of people represented by each representative adding up to however many seats that adds up to, there would have to be some amount of rounding given voting districts are per state but the only increase in the number of representatives would be correlated with population size which negates dilution of representation rather than create it as you suggest.

I actually don't think there is an issue with rounding large numbers up by more than one, the system should be based logarithmically and thus 22.5 is closer to 24 than 1.5 is to 2
Makes sense, its proportionally a smaller change, so the seats per capita is affected less
Concentrating power based off the power a state already has could increase corruption. However I don't confidently back favoring smaller or larger, I think both sides have good arguments.
@@bkm8556 I think my personal ideal would be to round normally, if you over shoot by rounding up too much increase the divisor until you have the correct number, if you under shoot reduce the divisor until you have the correct number.

I instinctively think what's more important is how much error each state has rather than the Alabama paradox or the quota rule. That is, I think we should allocate seats to whichever state has the highest error error is their actual seat divisor. I _think_ this is very similar to what the Hill method is doing but maybe the squaring helps with small vs. large states.
Is it the case that giving a seat based on minimizing an individual states error that the total error of all states could increase, and if so is that an issue? Probably an individual states error is a bigger deal than the accumulative but I dunno
Yes I was thinking the same, drop everything except allocating seats in such a way as to bring each divisor to as close as possible to each other while being able to adjust the number of seats based on a specific constraint. I.e say if every census period you could add or remove up to 5 seats either way, this combined with a method that minimizes disparities would probably yield the most equal result.
Another simple improvement is to remember the rounding from each election and add them back before apportionment for the next election takes place.
So, with two states with 1501 and 1499 inhabitants and a total of three seats, each state would generally alternate between having 1 and 2 representatives.
"It's just rounding, nobody can argue with that" well, certainly not a circle at least XD

Yes, there is still some problems with these 'capped methods' where their values do not grow correctly compared to relative population growth.
The quota rule doesn't seem intuitive to me? Rounding up and down might result in a different percentage deviation for large and small populations. So rounding up 1.01 to 2 is almost +100%, but rounding 23.01 up to 25 is more like +8%

The columns are not even reporting the same thing at all, these are two different statistics. The numbers shouldn't be the same: apportionment population and resident population are two different things.
Of course, the apportionment population should be *larger* than the resident population, which in these cases they're not, so there's still a mystery there, but the "original source" you presented also says clearly PRELIMINARY at the top in the title, so no you haven't found the original source, just a preliminary draft.
It took me way too long to realize "Squaryland" was Maryland.
New method:
(1) Calculate ideal representation amongst the states and truncate the fractional components.
(2) Determine the number of representatives R, by which the house falls short
(3) Each state puts forward 1 candidate
(4) Thunderdome to the last R candidates
wow 42 minutes congratulations! Thank you I really love your videos!!
I know it's not really related to methods of apportionment, but I can't help but wonder how the Wyoming Rule would play into all of this: setting the total number of representatives so that the average population per representative in each state is equal to that of the least populous state (currently Wyoming).
That would require a creation of more seats in Congress, which is somehow illegal, despite the fact that it could probably be challenged as damaging states that should have the missing representatives. It would be about 500 more total reps.
@@vxicepickxv Only about 135 for 569 total Representatives, If you leave the Senate out of it.
@16:35 how does 24.8614 (popNT/dj) round down to 23?? It should be 24, surely. I'm lost here.
The state of New Hampshire has to deal with the same problem when apportioning representatives to the state house of representatives (the number of representatives is high enough that towns are frequently entitled to more than one, and the state constitution prohibits splitting towns into smaller districts). Interestingly, it uses floterial districts (en.wikipedia.org/wiki/Floterial_district), which are very similar to Matt's idea of time sharing a representative, but instead of each selecting a representative for part of the time, multiple areas that are entitled to fractional leftovers are joined to create a second district that floats over a first district. The second district then uses most of the fractional entitlement to representatives. I would love to see him tackle the math of the fairness of that scheme.
Is it me or at 17:16 the rouding is wrong ?
24.86 rounded down is 24 not 23
and 11.03 is 11 not 10
Washington had spent years as a surveyor, dealing with math(s) and jealous landowners. He'd have been the first one to smoke out such problems!
did you use an actual audio clip of Destin Sandlin at 22:45, when Alabama says "All right, I'm feelin pretty good"?
Cuz-in Alabama, everything is possible. lennyface
6:05 until this point I wasn't sure if you had managed to significantly change the style of an actual excel-like something and were recording your screen or if you were just animating what excel would be like if only it had matt-parker-animation-style cells.
I should've known, you didn't use a $ on the row number but it still worked.
@@shelvacu wish they'd use R1C1 style. That makes so much more sense.
instead of $B4/$B$2, you would have RC2/R2C2. The most common kind of references (reference to the same row or same column, or absolute references) don't require special symbols.
and the formula would look the exact same in all the cells you pull it down into, much easier.
@@JNCressey Even better, IMO, would be to use tables and structured references.
I have an idea. Instead of making each rep's vote worth 1 after everything is allotted, why not allow the votes to be worth fractional values? For example, a state with 3 reps that should have gotten 3.6, each rep's vote is worth 1.2 instead of 1. This ensures that each state has the right amount of voting weight, with no violations or paradoxes.
You try telling Mississippians that Californian Representatives get more of a vote than them.
In all seriousness, mostly because people don't like thinking a Bill passed by one tenth of a vote. Especially if you end up rounding to significant figures or decimal points that people don't like. If a state has a decimal of .345, theyre going to be great proponents of 2sigfig- what I learned in my math classes! A good American rounding!
But the closer to 4 the last digit gets without going over, the more likely it is you'll be of the opinion we should do it FAIR, and keep going to figure twelve. A nice American number, twelve. And we don't have to write it all down at the end, we can round then, we just need it for accurate calculations in the middle bit.
But the real problem is you don't have a time machine. This solution would be so unbelievably unintuitive that it could only be set up by people already setting up a political system 'from scratch' (yeah, total coincidence you've got a bicameral legislature with one appointed and one elected house. mhm).
It's annoying to hear "this won't happen because people don't think it can happen, but, well...
Maybe you'd have more luck implementing it in local Government?
Legal fictions are incompatible with justice. If the representation was meaningful this sort of problem wouldn't come up. If jurisdictions were meaningful likewise.
I believe this idea was actually proposed in Congress some time ago, but I couldn't find who or when... I believe it was in the '80s or '90s by Rep. Norton (Delegate for District of Columbia) but I may be wrong on both counts.
@@havenbastion a lot of words to say nothing at all.
To suggest there's no mathematical problems in meaningfully representative systems is ignorant at such a basic level you might as well resit playgroup.
@@MarkusAldawn Remember, at least one state has attempted to legislate the value of pi to be 3. Because, that's totally a thing controlled by statute. A significant fraction of US high school graduates have no idea what fractions or decimals mean. And they vote.
You start to explore at the end, "What if partial representatives existed?". Why not go all the way and give each state a given # of representatives exactly apportioned to population and let the states divide those representatives however they wish. ie if the divisor is 40,000 and the state has 110,000, then they would receive 2.75 reps that they could send, either 1 rep with 2.75 votes, 2 reps with 1.375 each or why not let them do 1 rep with 1.7 votes and another with 1.05? (maybe they wanted to allocate their reps voting power in exact proportion to the votes received in the election) There would be a need for meta rules potentially Some potential examples: Each rep sent must have at least 1 vote, Each rep sent may not have more than n votes (2 being the obvious #, although this isn't as needed as the former, if a state wants a mega rep, why not let them?)
This would open the possiblity for states to do away with districts (yay, gerrymandering gone, although states would still exist) and just allocate their reps based on votes received in one large election. Yes house voting would get more complex, but technology has advanced somewhat since the late 1700s. Also if states held statewide elections, I'd expect 3rd parties to start earning more seats (only need 2% of CA voters to get a seat with > 1 vote, bet Green could get at least one, etc). Although this last comment is likely why no major parties would ever decide to do it as it would have the potential undermine the party slowly or fracture into interest groups rather than a party.
When you recognise Destins voice as the state of Alabama
5:09 THE DIVISOR IS NOT AN ABSOLUTE REFERENCE
I think the start of the video as-is was great, although I'm glad you still included the information about the first presidential veto!
What a refreshing veto, too. "I'm not signing this because I don't think it's Constitutional." Compare with present day "I'm signing this executive order even though the Supreme Court will probably strike it down. Because it'll take them a couple months to do so, and in the meantime we can enjoy my awesome if unconstitutional policy."
40:46 Ack, a Tie?!? That's the WORST possible outcome. To explain:
If there is a tie, then the top two candidates (the ones who tied) are put in a run-off election in the US House of Representatives. HOWEVER, it is not 'each representative gets a vote' which would be 'roughly' proportional to the population (we just saw how it's never correctly proportional), id is 'each STATE gets a vote,' with no clear indicator of how the representatives for a state choose what their 'one vote' will be; they could co 'majority rule,' they could debate until they reach a consensus, or a senior representative could bully the junior representatives to agree to him being the one with the choice.
'Voting by rep' favors the larger states, which seems logical as those are the states with larger numbers of Electors, 'voting by state' GREATLY favors the smaller states, as Rhode Island's vote can completely cancel out California's vote.
Love this! My first thought, early in the video, was effectively to normalise before ranking the fractions. If I weren't ADHD, I'd be setting that up in a spreadsheet right now -- but I have so many other things to procrastinate on! :D
I like how close each of these fictional states in the United Shapes has a name close to a real US state. Makes it more enjoyable.
I get Squaryland, Octiana and Rhombus Island, but New Triangle and Circula don't remind me of any US states.
@@liborkundrat185 Those last two don't ring a bell for me either, but it's still a nice touch.
25:35 I think you can have both. An example would be the Jeff's method but with a limit not to break the quota rule. So taking min(floor(POP/DJ), ceil(POP/D)) instead of floor(POP/DJ) based on the names from 18:00.
You are effectively adding a special exception to remove the quota rule breaks... every time that exception triggers there would be a chance to have Alabama paradoxes again.
@@raisins7777 No, Alabama paradoxes are not possible here.
1) By definition of DJ we decrease it until we have desired total seats so with more seats DJ would be lower. This means floor(POP/DJ) would be higher or equal.
2) D will be lower so ceil(POP/D) would also be higher or equal.
From 1) and 2) min(floor(POP/DJ), ceil(POP/D)) will be higher or equal so there will be no Alabama paradoxes
@@michal2527 -The flaw in your proof is in point 1). You conclude that "floor(POP/DJ)" (normal hamilton's method) will always be equal or higher with more seats. That is exactly claiming "the hamilton method doesn't have alabama paradoxes", and as this video demonstrated it does have them. The apportionment functions we are comparing are functions of DJ. But DJ is itself that value which gives the correct total seats for a given apportionment function. Consequently DJ is sensative to both the total number of seats and the function itself. So "more seats always lowers DJ" sounds intuitively correct but on rare occasions it is false.-
@@raisins7777 The Hamilton's method would be floor(POP/D) with a +1 sometimes (the +1 depends on the results of other states and this is why we get Alabama paradoxes).
floor(POP/DJ) is Jeff's method not Hamilton's and it does not have Alabama paradoxes.
@@michal2527 Whoops. I though that seemed a little too easy. That's still the section where the mistake is though, and the blathering about hamilton's method is sort of still why. Your function is unstable because of the peicewise nature. Some of the states will be using the ceil part, and that part doesn't use the DJ, and for those states your method IS essentially a hamilton variant and therefore subject to the same issues. I made a model of your method to confirm and indeed found an Alabama Paradox after a bit of fiddling:
min(floor(pop/DJ);ceil(pop/D)) method:
800 seats
apportion X,Y,Z = 5, 210, 93
801 seats
apportion X,Y,Z = 4, 211, 94
Paradoxical loss for State X

I usually don't understand everything that these videos show even though it might be a bit simplified. However, I do love watching them, The way you you explain things reminds me of my favourite teacher in school
On initially hearing it, I like his proposed buddy system for states rounding to half a representative because it could encourage more cooperation and understanding in this time where many people seem bound and determined to villainize the "other side" in their heads.
16:37 somehow the divisor Jeff isn't correct in this particular instance, those numbers are the result of dividing the populations by 880 rather than by 930. The rounding still ended up rounding as if the numbers had been divided by 930, just the numbers for =pop/DJ are using DJ=880.
Not trying to bash or hate, just pointing out in case anyone else was looking at those numbers wondering why 24.86 rounds to 23 and happens to look at the comments to see this.
also at 19:17 the POP/DA of all other States besides New Triangle goes back to the 930 value instead of up to the 960 value
bro something with the math at that point is completely off, the values of POP/DA go up after increasing DA from 930 to 950, except New Triangle. and i thought matt was the expert of Spreadsheets
Right. Getting a pro life state to agree with a pro choice state that wants taxpayer funded abortion up to and including after birth (see Virginia’s governor) is a great idea.
I dont know how to share space with people that can't tell you what a woman is.
Hey Matt,
I wonder: haven't you considered using closed captions for your videos, even autogenerated ones? It could really enhance the viewing experience.
I keep turning them on, RUclips keeps not displaying them.
I have to agree with Stan, they make a huge difference. I usually watch videos in high ambient noise conditions and it makes some videos unwatchable. Not this one though, the volume isn't terrible and you enunciate well.
Unfortunately it seems to make the closed captioning reliable and accurate creators need to make them rather than using the auto-generated ones.
I've seen this same problem elsewhere. Or the auto-CC are terrible, my Pixel 5's auto generated CC will be more accurate. But those start lagging farther and farther behind very rapidly...
It's too bad Google removed the option to have users create CC.
I dislike having cc keep turning on by itself already. Not sure why but it's annoying.
@@deyesed You can change it in your profile settings, to either be on or off by default.
@@culwin there's only an option to always have it on, no choice to have them permanently off.
