I do wonder what the statistics would be for the other countries

I don’t think many western European countries would do much better.

I would go so far as to say this is true for most European countries aside from the “Main” ones with distinct shapes.

Western european countries would definitely do better. Every time I see one of those videos of a guy on the street asking people geography the Americans are completely worthless but and random european is almost perfect. Americans can’t even get their states of our own country correct
