Several years ago the economist had results from a geography quiz given to citizens of various countries. Europeans generally scored higher than Americans, but not by much.

Speaking of Minnesota, I haven't met a European (who isn't living in the US) who knows where Minneapolis is (my response after they ask where I am from). About 1/10 have even heard of it. I always follow with "it's 500km northwest of Chicago," and maybe 1/4 claim to have an idea where Chicago is.
