Publishing for children study

Fully 55% of buyers of works that publishers designate for kids aged 12 to 17 (YA books) are 18 or older, with the largest segment aged 30 to 44. Accounting for 28% of sales, these adults aren’t just purchasing for others—when asked about the intended recipient, they report that 78% of the time they are purchasing books for their own reading. The insights are courtesy of  a biannual study from Bowker Market Research that explores the changing nature of publishing for kids.
