Twice as much teens than adults on social networking sites

ARS Technica cites figures from a study by Pew Internet and American Life Project about social networking sites, the report indicates teens on social networks still outrank adults 2-1 and that 35 percent of US adults who use the Internet have at least one profile on a social network such as Facebook, MySpace, or Twitter. Pew's report also suggests men and women are equally as likely to be social network users, but other studies suggest men are more likely to use it for networking for business.

According to a study by Pew Internet and American Life Project, 35 percent of US adults who use the Internet have a profile on at least one social network such as Facebook, MySpace, or Twitter. This is a significant increase over just eight percent in 2005, but still a far cry from the 65 percent of US teens aged 17 and younger who use social networks. While adult social network usage doubled in a year to reach 16 percent in 2006, it took another two years to double again around December 2008.

The report includes a broad range of demographic data, including a more in-depth breakdown of social network use among age groups. Unsurprisingly, 18-24 year-olds are the most likely to have a social network profile, with 75 percent having registered with at least one site. The numbers steadily trend downward from there, however, with 57 percent adoption among 25-34 year-olds and 30 percent among 45-54 year-olds, finishing with just 7 percent of Americans aged 65 and older on a social network.
