Not an American. I read a lot but I can't think of a book I read last year. I don't think "didn't read a book" is that useful for inference about imagination, literacy, education etc., unless it's also matched by watching an enormous amount of linear or episodic television. "Didn't read a book" might, however, be a meaningful proxy for shorter attention spans. I think it could be in my case, even though I read voraciously.
