The Pew Internet and American Life project has released a new report on reading, called E-Reading Rises as Device Ownership Jumps. It surveys American book-reading habits, looking at both print books and electronic books, as well as audiobooks. They report that ebook readership is increasing, and also produced a "snapshot" (above) showing readership breakdown by gender, race, and age. They show strong reading affinity among visible minorities and women, and a strong correlation between high incomes and readership. The most interesting number for me is that 76 percent of Americans read at least one book last year, which is much higher than I'd have guessed.
