So it’s been a few years since I did the first comparison of the number of registered users on www.projecteuler.net, and the population in the respective countries. It would therefore be interesting to see now if anything have changed since then.
The statistics are based on the current population data, as given here by January 10. 2012.
Only countries with a population higher than 100,000 will be in this list. Ratios are registered users divided on population, and is divided by 1000 again to ease reading. A more «true» comparison would be to use solved problems instead of only registered users.
One may observe that Slovenia has improved a lot, moving from 8th to 5th, while Finland drops from 3rd to 7th. Iceland was chosen not to be on the list in the previous comparison, so the introduction of this country shifts the rankings by 1 when comparing rankings.
