This question already has an answer here:

This is a follow-up to Where in the world do Stack Overflow users say they are from? As requested by Kyle Cronin, I've calculated the number of Stack Overflow users per capita. I'm making this a separate post since there were already so many charts and tables on the other one. But, lest anyone accuse me of rep-whoring, I'm making this post CW.

I have once again provided the full data in a Google Docs spreadsheet, and it is also available in Excel format.

Edit (2010.01.06): My previous post had incorrect per-capita data for the states in the US. I think I pasted the population data into my spreadsheet sorted by state name, when I had sorted the data by number of users. The result was that states had the incorrect populations. I have updated the chart and the Google spreadsheet to reflect the accurate numbers. And I apologize to all the Wasingtonians (state and DC) and Delewarians I offended. :)

wow, very interesting information –  adardesign Oct 14 '09 at 14:48
100% of we Super Mario Landians are Stack Overflow users, you discriminating monster. –  XMLbog Oct 14 '09 at 14:49
Bermuda and Isle of Man? I guess there are a lot of people interested in "boat programming". –  gnostradamus Oct 14 '09 at 15:05
Isle of Man has a lot of banking (for tax reasons), so it may have more IT people then expected. –  Ian Ringrose Oct 14 '09 at 15:19
@gnovice: @Ian Ringrose: actually if you look at the full data, only one SO user with rep >= 1000 in each of Bermuda and Isle Of Man. But their population is so low that, per capita, they come out on top. –  Kip Oct 14 '09 at 19:44
Illinois second in user per capita...and we could not get a Dev Days in Chicago. –  Miyagi Coder Oct 14 '09 at 20:56
I suspect people from tiny, exotic locations are damn proud of it. And hence more likely to accurately fill in the location. –  Stu Thompson Nov 8 '09 at 19:08
@Stu: ...or people from boring places like Ohio are more likely to lie about it and put Bermuda. –  Bill the Lizard Nov 8 '09 at 20:12
@Bill the Lizard: I think you mean the people in Wyoming. –  Stu Thompson Nov 8 '09 at 20:25
@Stu: some of us like Wyoming. Ohio, on the other hand... –  quack quixote Nov 8 '09 at 20:36
Hey now, us Ohioans come in at a respectable 3rd among the states. –  gnostradamus Jan 6 '10 at 5:47
@Franks and Beans: @gnostradamus: After Pollyanna posted an answer yesterday, I looked at the data and realized the per-state data was incorrect. I've updated the post with the correct data--see the edit info at the top of this post. –  Kip Jan 6 '10 at 14:27
@Kip: Dang! Ohio isn't even on the list anymore. –  gnostradamus Jan 6 '10 at 15:39
@Peter: I assume it's a temporary thing. Wait a little bit. –  Ladybug Killer Jan 6 '10 at 21:49
The figures for the UK don't seem to add up. Unless there are loads of highish rep users hanging out on the Channel Islands. –  Tom Hawtin - tackline Jan 7 '10 at 5:51

I think there is a strong relation with "good English speaking countries" and SO country usage. Look at Europe: Esp. England, Ireland but also the (well-known English speaking) Scandinavian countries.

Other countries might prefer Q&A fora in their native language.

Users per million "fluent" English speakers (writers) might well give very different results. –  Tom Hawtin - tackline Jan 7 '10 at 5:46

Given 4M population in Michigan, I suppose that means there are 88 users here.

I propose a party.

share|improve this answer
Actually, Wikipedia says 10M in MI. There are 34 Michiganis here with rep >= 1000. But this post made me realize that my per-capita data for the states in the US was very wrong. I've updated my post. MI is now at 3.3988 users per 1M residents, ranked 33 in the nation. –  Kip Jan 6 '10 at 14:24
Oh sure, cut us down to barely a roomfull of users. I see how it is! –  Adam Davis Jan 6 '10 at 18:20

Although the population of cities is somewhat subjective, could you do an analysis of per-capita for cities?

share|improve this answer
Sorry, I'm done with tedious data gathering for the moment. You can take the raw data from my other post, and look at the "by city" tab here: spreadsheets.google.com/… . If you want to go look up the actual population for each of those cities, and then calculate users/population, feel free. But there are 743 cities represented, which is a lot to look up. –  Kip Nov 9 '09 at 15:49
