Report: Pew Internet: Generations Online in 2009 (Jan. 09)

Jones, S., & Fox, S. (2009). Generations Online in 2009 | Pew Internet & American Life Project.

Contrary to the image of Generation Y as the “Net Generation,” internet users in their 20s do not dominate every aspect of online life. Generation X is the most likely group to bank, shop, and look for health information online. Boomers are just as likely as Generation Y to make travel reservations online. And even Silent Generation internet users are competitive when it comes to email.
