Is there statistics on how popular books such as Harry Potter and Twilight, increased people to read?

lalalux33: Is there statistics on how popular books such as Harry Potter and Twilight, increased people to read?
I’m writing a paper on how books are very sacred within society. After gathering some information I found out that books such as Harry potter and Twilight are being banned within many countries but I think that they’re really important in that after the movies, many people began to read these books. I feel that these books actually encouraged people to read and that’s really important. Does anyone know any statistics or articles that show the increase in reading after these kind of books?
I’m having trouble finding them.

I don’t think that it matters all that much that people start to read if they won’t move on to better things, I can’t say that of Harry Potter, I think it’s a good book.

But Twilight I consider pure crap, I don’t care if it makes a 100 million more people read, they might as well be reading the back of cereal packs, that would be perhaps more intellectual.
