Millennials may be thought of as the iPhone generation, but it seems plenty of them still enjoy an old-fashioned book.Pew Research surveyed 6,000 Americans ages 16 and over for a report called "Younger Americans and Public Libraries." They found that 88% of adults under 30 read a book in the past year, while only 79% of those 30 and over read one. Adults 65 and over were the age group least likely to have read a book this year, according to Pew.It is worth noting that 37% of adults ages 18-29 reported that they have read an e-book this past year. But 43% of Millennials reported reading a book — in any format — on a daily basis, a rate that Pew called "similar to older adults."
