62% of Americans aged 12 and up report having a profile on a social network, and Facebook is easily dominant, used by 58% of Americans of that age, per results from a study conducted by Arbitron and Edison Research. Among age groups, 18-24-year-olds are the most likely to have a profile on a social network (86%), and also sport the highest average number of Facebook friends, at 510.
12-17-year-old Facebook users are close behind, with an average of 506 friends, with a significant drop among older age groups.
