65% of online adults use social networking sites

Fully 65% of adult Internet users now say they use a social networking site like MySpace, Facebook or LinkedIn, up from 61% one year ago. This marks the first time in Pew Internet surveys that 50% of all adults use social networking sites.

The frequency of social networking site usage among young adult Internet users under age 30 was stable over the last year – 61% of online Americans in that age cohort now use social networking sites on a typical day, compared with 60% one year ago. However, among the Boomer-aged segment of Internet users ages 50-64, social networking site usage on a typical day grew a significant 60% (from 20% to 32%).
