Not sure if this was just featured today or I just haven't noticed it in the past, but congrats on this feature (and the "Least Light Pollution one" as well)!
I wonder how sea area is factored in to the total area. I tried a bunch of small island states that are very densely populated if only land area is considered, but which are often very sparsely populated if you include coastal waters (and especially if one was to include EEZs, which clearly isn't the case for the source).
Wow. Funny how Trinidad and Barbados where the first Caribbean islands that came to mind ^^. Probably because they are the most common tourist destinations out of the smaller Caribbean islands
It's mostly densely populated, highly-developed countries that use a lot of electricity and have a highly urbanized population. There are quite a few countries from every continent that don't make the cut smaller than South Korea.
