A new paper released last week by the Pew Research Center found that print books continue to be American adults’ preferred reading format, though digital formats continue to make inroads.

According to a survey of 8,046 U.S. adults conducted last year from October 6–16, 64% of respondents said they had read at least part of a print book in the last 12 months, down from 72% in 2011. During the same time span, the percentage of respondents who read an e-book rose to 31% from 17%, while audiobook usage jumped to 26% from 11%.

The number of e-book readers has seen only a small increase since 2014, when the percentage of adults reading e-books rose to 28%. Audiobook readership, however, has had stronger gains since 2014, when 14% of readers preferred an audiobook. Adults favoring print books was at 69% in 2014.

Among the survey’s other highlights were the findings that college graduates were more likely than non-college grads to have read a book in the past year; Americans under 50 were more likely than older adults to read e-books and audiobooks; white Americans were most likely to read print books, whereas Asian Americans stand out in their use of e-books; and women were more likely than men to say they have read a book in the past 12 months.
