A full archive of Pew Research Center reports on different social media platforms such as Facebook, Twitter, Instagram, Pinterest and Linked In as well as about social media usage on mobile devices in general can be found at:
Age is strongly correlated with social media usage: Those ages 18 to 29 have always been the most likely users of social media by a considerable margin.
Nearly two-thirds of American adults (65%) use social networking sites, up from 7% when Pew Research Center began systematically tracking social media usage in 2005.
Pew Research reports have documented in great detail how the rise of social media has affected such things as work, politics and political deliberation, communications patterns around the globe, as well as the way people get and share information about health, civic life, news consumption, communities, teenage life, parenting, dating and even people’s level of stress.
In 2005, 8% of men and 6% of women used social media.
A special analysis of 27 national surveys of Americans across the past decade documents this substantial spread of technology throughout the population, although the overall number of users of social networking sites has leveled off since 2013.
The figures reported here are for social media usage among all adults, not just among those Americans who are internet users.In many previous Pew Research reports, the share of social media users has been reported as the proportion of who had adopted such sites, rather than the full adult population, which continues to include a relatively small share (currently 15%) who still remain offline.While usage among young adults started to leveled off as early as 2010, since then there has been a surge in usership among those 65 and older.In 2005, 2% of seniors used social media, compared with 35% today.
Today, 90% of young adults use social media, compared with 12% in 2005, a 78-percentage point increase.
At the same time, there has been a 69-point bump among those ages 30-49, from 8% in 2005 to 77% today.
