Scholastic has over 50 million digital and print copies of the books in The Hunger Games trilogy in print.

The publisher broke down those figures for the individual books in Suzanne Collins‘ series as well: 23 million copies of The Hunger Games; 14 million copies of Catching Fire and 13 million copies of Mockingjay. These big sales drove significant increases in revenue last year.

Here’s more from the publisher’s earnings report: “In the fourth quarter of fiscal 2012, revenue rose 24% to $678.5 million, from $545.3 million in the same quarter of fiscal 2011 … Strong sales in Children’s Books and International, especially of The Hunger Games trilogy, again drove substantially higher results.  Consolidated earnings per diluted share were $1.76 in the fourth quarter, compared to $0.78 a year ago. In fiscal 2012, revenue was $2,148.8 million, up 14% from $1,887.9 million a year ago.”
