On my last trip abroad, to New Zealand last Feb, the group I met up with was a mix of mostly British (maybe 20-ish, 4 Swedish, an Aussie, 2 Dutch, an Italian, a Swiss, a couple of Canadians, and a German; plus our 2 Kiwi guides. Great group of people, only 1 knew where Charlotte was , because he had been there on business before. I don’t recall any of the others being aware of North Carolina esxcept for the Canadians.
Of course, I didn’t expect them too - just as I’m not familiar with the anything besides the larger / more prominent places from their countries. Of course, with the exception that I can draw a damn good map of Europe in 1419 due to playing so much Europa Universalis. I also do OK with England, having lived there for a few months.
So, my guess, would be that, in general, people from other countries will be knowledgable of US geography in the way that we are with theirs - that is to say, they’ll know where the big stuff is (NYC, California, the Grand Canyon), be familiar with some general stuff (the Midwest, New England, the Rockies) and have no idea where your little town is. They may have the added advantage of having learned some more through pop culture.
ETA: When I went to China, no one knew where anything besides NY and California was… (most of the above was aimed at the western world. I would imagine that people from small towns in Nepal know considerably less)
