Social media sites have always skewed younger, typically under 25 years old. However, those demographics are changing for some sites. The most age-diverse social sites are Facebook and LinkedIn, followed by Google+, Twitter and YouTube. Meanwhile, the most age-polarised social sites are Instagram and Tumblr, with 39 percent and 45 percent of their active users between ages 16 and 24.
The migration of the 16-to 24-year-old age group from Facebook and other established platforms to newer social platforms is expected to continue for the foreseeable future. Quora, Instagram and Pinterest are among the sites that are poaching the most 16-to 24-year-old users from established sites like Facebook, Google+ and YouTube.
