A survey by Pew Internet states that 64% of online adults in the US use social networking sites – that amounts to half the full adult population. Among internet users, social networking sites are most popular with young adults under age 30. As of August 2011, there were no significant differences in use of social networking sites based on gender, race and ethnicity, and household income. The results are based on data from telephone interviews conducted in July and August 2011, among a sample of 2,260 adults, age 18 and older.
