Total revenue for the 1,209 publishers who submit figures to the AAP’s StatShot program rose 4.9% in 2014 to $15.72 billion, the association reported this morning. The increase was led by the children’s/young adult segment, while sales of adult books saw a slight drop.

In the children's/YA segment, revenue increased 20.8%. In adult books, sales fell 1.4%. Meanwhile, the K-12 instructional materials segment posted a 10.7% increase. Sales of professional books increased 10.1%, and sales in the religious book segment rose 1.3%.

Within the adult trade segment, e-book sales rose 1.0%, to $1.29 billion, at reporting companies and accounted for 27.2% of adult trade sales in 2014 compared to 26.6% in 2013. Trade paperback sales increased 2.3%, but sales of mass market paperback fell 4.2%. The hardcover segment had the largest decline among trade formats with sales off 8.2%. Sales of downloadable audio rose 27.2%, helping to offset a 7.7% decline in sales of physical audio.

In children’s/ya, e-book sales jumped 33.6%, to $227.3 million and accounted for 12.0% of sales, up from 10.9% in 2013. The board book segment had a good year as well with sales up 33.0%. Paperback sales rose 24.4% and hardcover sales increased 15.0%.
