Almost entirely fiction, a couple dozen a year. I'm currently rereading a book series with around 20 books, I think.
Not considering audio books in the statistic is a little weird and comes off as attempted gatekeeping... If someone has taken the time to consume book media, it shouldn't matter if it was listened to or not. My wife is dyslexic and listenes to quite a few audio books a year, but can only finish a couple print books.
