I'd like to find some book sales statistics on the most popular books for people in the 16-24 age group. Any idea where I could find something like this?
If no such thing exists, I'm thinking about carrying out my own survey.

The booktrade uses Bookscan - which is often described as the source of many authors' woes - but it costs a fortune to subscribe. The lists in the back of Saturday's Guardian Review are pretty comprehensive, but I don't think they do children's very often.
