Taken from here. Statistics were gathered in 2003.
1. 80% of Americans want to write a book. Operative word: want
2. 1/3 of high school graduates never read another book for the rest of their lives.
3. 42 percent of college graduates never read another book after college.
4. 80 percent of U.S. families did not buy or read a book last year.
5. 70 percent of U.S. adults have not been in a bookstore in the last five years.
6. 57 percent of new books are not read to completion.
7. 70 percent of books published do not earn back their advance.
8. 70 percent of the books published do not make a profit.
9. 53 percent read fiction, 43 percent read nonfiction. The favorite fiction category is mystery and suspence, at 19 percent.
10. 55 percent of fiction is bought by women, 45 percent by men.
11. About 120,000 books are published each year in the U.S.
12. A successful fiction book sells 5,000 copies.
13. A successful nonfiction book sells 7,500 copies.
14. On average, a bookstore browser spends 8 seconds looking at a book’s front cover and 15 seconds looking at the back cover.
15. Each day in the U.S., people spend 4 hours watching TV, 3 hours listening to the radio and 14 minutes reading magazines.
Somehow I doubt the statistics have improved in 2007.
