I think the survey team didn’t do a per capita visualisation because response rates will probably vary a lot between countries for reasons other than the number of EAs per capita.
We have reported this previously in both EAS 2018 and EAS 2019. We didn’t report it this year because the per capita numbers are pretty noisy (at least among the locations with the highest EAs per capita, which tend to be low population countries).
The last time we reported this was 2020, with the caveat that “Iceland, Luxembourg and Cyprus, nevertheless have very low numbers of EA (<5) respondents. This graph doesn’t leave out any countries with particularly high numbers of EAs, in absolute terms, though Poland and China are missing despite having >10.”
We’ll discuss the details more in the post we are putting together on this (hoping to release this month), but there is indeed quite a lot of noise when you look at EAs per capita, and in particular the highest EAs per capita countries, due to small populations and small numbers of respondents, often close to zero (e.g. small countries can jump in and out of the top rankings based on having 5 or 0 respondents in a year). In the full post we’ll additionally examine results for composites of years (e.g. 2020-2022), and which countries outperform what a model would predict (though that will be heavily caveated).
Yeh, as we note here:
