As a group, Millennials are as likely as older adults to have used a library in the past 12 months, and more likely to have used a library website. Among those ages 16-29, 50% reported having used a library or bookmobile in the course of the past year in a September 2013 survey. Some 47% of those 30 and older had done so. Some 36% of younger Americans used a library website in that time frame, compared with 28% of those 30 and older. Despite their relatively high use of libraries, younger Americans are among the least likely to say that libraries are important.
