The Pew Internet Survey has released their latest survey (free download) of social media use and the long term trends are striking. The organization started tracking use in 2005 when social media use was by just 7% of the US population. Now, 65% of adults use social networking sites. Our chart shows the increases by age group.

Ninety percent of those between 18 and 29 use social media, which is not a surprise. Those social media users who are 65+ has more than tripled from 11% in 2010 to 35% in 2015. The report includes data about social media use by various demographics including income, race, gender, community, and education.
