“Fewer”
Basically no one was reading books in America aside from an extremely brief resurgence during Covid
Men basically read no fiction, women account for 80% of fiction sales. 46% of Americans haven’t read a book at all in the past year. 82% who do read read under 10 books a year
The entire industry is propped up by a shrinking population that inhales books/ebooks. You’ll occasionally see that the average American reads 12ish books a year but that’s because there’s some people pulling serious weight for all the deadbeats who can’t be bothered to read a single book ever
