Books and nationality

This week, instead of a Friday Five (which can be summed up by the following:  I finished hanging all the pictures in my room, and that I am going hiking tomorrow, so not many interesting happenings in the life of Elizabeth this week), I am going to talk about something that I've been curious about.

As I was looking through the books and authors I've read to meet the 2013 European Reading Challenge I came to a startling discovery.  I'd always had the niggling feeling I primarily read American authors with a smattering of UK authors and the occasional Australian.  And that's EXACTLY what I've been reading.  With addition of Juliet Marillier, the one Kiwi author I've read.  Here's what I've discovered:

1.  ALL contemporary YA authors I have come across are American. (the one exception I can think of is Finding Cassie Crazy by Jaclyn Moriarty, and I discovered that in high school)
2.  The ONLY genre I've read non-American authors is in sci-fi/fantasy, but I'm guessing half of the books I've read in the genre are still American. (With the exception of Rita Charbonnier who wrote Mozart's Sister, a historical fiction novel, and I know over the years there have been a few others here and there.  My point is there aren't very many of them)
3.  Classics don't count.  I'm talking books that have been published since I've been alive


(Except you know authors not kids.  Kids I can't escape. THEY ARE EVERYWHERE.)


I know that much of this can be explained by a few things, primarily that

1.  I live in America
2.  I read primarily YA fiction and of that primarily contemporary or sci-fi/fantasy, and maybe those genres have a higher American author ratio to those of other nationalities
3.  I am limited to countries that speak English primarily, or the books are popular enough they've been translated
4.  America and the U.K. have very high populations, so it makes sense there are more authors from there


Is it just that I'm American? I've read blogs written by people all over the world, but I feel like I'm still seeing the same books there.  I can't think of a single really big name author (keeping in mind I'm dealing with YA, not normal fiction.  In normal fiction it's still primarily American and UK fiction I'm finding, but I can think of plenty of authors who don't fit in that category) that isn't American or from the U.K.  Can you?
