I have a library in my house.

A surprisingly large number of people over here don't read either. I still remember how incredulous I was as a child when I stayed with a friend at her parents' house for a week one summer and, after asking if I could borrow one of their books to read one afternoon, was told they didn't have any books at all.

I belong to two book clubs; each club has between 30 and 40 members....all over 55 y/o. No, Americans do not read enough. In fact, I asked the librarian / book club leader if she wanted the names of Spanish writers to read their work (translated to English). She didn't know who were Borges, Rulfo, Martí. Allende, Cortázar, Bioy Casares.....I was afraid to ask her if she knew about Cervantes.

This is probably very common, but don't ask them if they know anything about the bible or scriptures, because they don't. If more people read what it really says, there would certainly be more non-believers. I think most Americans like to talk about being religious because it's so hip and they HAVE to fit in. It's all about being in a "cookie cutter" society.

Just because they own a copy of the Bible doesn't mean they read it, although they will look things up, like how God doesn't like gays and they will follow along with the preacher if they attend church. In my experience, however, non-readers exist but most people at least read popular fiction. Some non-readers are smart people of action- idiot savants, of a sort. Like artists too wrapped up in their craft to stop for reading or people who beware being influenced by other people's ideas. Others are just idiots.

The internet says it averages out to about 30, sounds in the ballpark. I usually read about one book a month and donate one book a month.

That is typical of white evangelicals, and "blue collar" US people in general.
They don't read.
Not even the Bible, although the religious ones give it lip service. If you ask them anything about it, they don't know and don't care.
