Who is into books? Generation Y. Generation Y, those born between 1979 and 1989, spent the most money on books in 2011, taking over long-held book-buying leadership from Baby Boomers. That’s according to the 2012 U.S. Book Consumer Demographics and Buying Behaviors Annual Review, the publishing industry’s only complete consumer-based report integrating channel, motivation and category analysis of U.S. book buyers. The Review, an information staple prepared by Bowker® Market Research and industry trade magazine Publishers Weekly, notes that GenY’s 2011 book expenditures rose to 30 percent — up from 24 percent in 2010 – passing Boomers, 25 percent share. And with 43 percent of GenY’s purchases going to online channels, they are adding momentum to the industry shift to digital.
