A study released Wednesday (PDF) by Pew Internet shows social networking adoption among adults is growing at a substantial rate, although the under-18 crowd still makes up two out of every three users. 35 percent of adults are now thought to have social network profiles, up from just 8 percent in 2005.
The figures may be a bit misleading though. Even among the adult population, there is a large disparity. While three out of four 18-24 year olds have a profile, only 7 percent of those over 65 do.
Like kids, adults are using social networks for personal use more than business use. However, some seperate their personal and business profiles over several networks, the report indicates.
Half have profiles on MySpace, and 22 percent on Facebook. Professional networking site LinkedIn is used by 6 percent.
