35% of US adults now have social network profiles, up from 8% in 2005. That’s still a smaller proportion that the 65% of teens — but a larger number overall.
The just-released the results of the Pew Internet & American Life Project’s December 2008 tracking survey shows that the use of social media still skews toward younger adults and drops off dramatically in the older age groups.

The numbers are evenly split along gender lines. Interestingly, black and Hispanic adults are more likely to have social profiles than whites. Adult users also tend to be more urban.
