Experian Hitwise came to these conclusions by sampling f 10 million U.S. Internet users to measure the online traffic to each social network.
The growth on social networks is, at least in part, being fueled by older users flocking to the sites like Facebook and Twitter. Experian Hitwise found that the 55-plus demographic on Facebook now comprises 13.53 percent of users, a growth of 108 percent from September 2008. Meanwhile, users between the ages of 18 to 24 and 25 to 34 still comprise the largest segment of users on Facebook at 26.96 percent and 23.31 percent, respectively.
MySpace also saw growth in the 55-and-up demographic, growing 26 percent to 6.84 percent over the past year. However, the older social network saw a 13 percent decline in users ages 18 to 24. The 25 to 34 demographic grew 12 percent to comprise 22.43 percent of users.
