I was surprised I couldn't find a graph like this already on the forum, so I made one and thought I would share it:
The data is from the 2022 EA survey,[1] and here is my sheet.
The main surprising thing to me is that English-speaking countries are less dominant than I expected, in this per capita framing. My vague sense was that the EA community was notably more popular in the Anglosphere than even in other rich countries, but eyeballing this data makes me think I was wrong: Northern/Western Europe seems to have quite comparable rates of EAs.
And what on earth is happening in Estonia? Perhaps some Estonian EAs can tell us all what you are doing that works so well!

Maybe there are quite different response rates by country, and this could explain some of the variance but I assume there isn't a large or systematic effect here.
If you're looking for more data, I think you can use Google Ads to estimate the number of searches for "effective altruism" (and probably filter per country). Searching for EA doesn't imply you're considering yourself an EA, but it might be a hint. Note that while you can do something similar with https://trends.google.com/trends/, it only shows relative numbers.
Thanks good idea, I have not done this myself but if anyone does, let us know the results!
