From Pew Research:
About a quarter of American adults (26%) say they haven’t read a book in whole or in part in the past year, whether in print, electronic or audio form. So who, exactly, are these non-book readers?
Several demographic traits correlate with non-book reading, Pew Research Center surveys have found. For instance, adults with a high school degree or less are about three times as likely as college graduates (40% vs. 13%) to report not reading books in any format in the past year. A 2015 Pew Research Center survey shows that these less-educated adults are also the least likely to own smartphones or tablets, two devices that have seen a substantial increase in usage for reading e-books since 2011. (College-educated adults are more likely to own these devices and use them to read e-books.)
