From the Pew Research Center:
The number of book readers has dipped a bit from the previous year and the number of e-book readers has remained flat, according to new survey findings from Pew Research Center.
Seven-in-ten American adults (72%) have read a book within the past year, whether in whole or in part and in any format, according to a survey conducted in March and April. That figure has fallen from 79% who said in 2011 they had read a book in the previous year, but is statistically in line with polls since 2011.
Many book publishers, researchers and retailers have wondered whether the introduction of e-books would impact book reading overall or lead to a decline in the number of books read in print. This year’s data show a slight decline in the number of American adults who read print books: 63% of American adults say they read at least one book in print in the past year, compared with 69% who said the same the year before and 71% in 2011.
