08/05/2013 - The Pew Research Center's Internet & American Life Project has been studying online adults’ social networking site use since 2005, and has seen substantial growth since then. Today, 72% of online adults use social networking sites. Although younger adults continue to be the most likely social media users, one of the more striking stories about the social networking population has been the growth among older internet users in recent years. Those ages 65 and older have roughly tripled their presence on social networking sites in the last four years—from 13% in the spring of 2009 to 43% now.
In this report we also studied online adults’ use of Twitter. The percentage of internet users who are on Twitter has more than doubled since November 2010, currently standing at 18%. Internet users ages 18-29 are the most likely to use Twitter—30% of them now do so.
