Just 51% of US individuals aged 13 to 17 say they use Facebook – a dramatic plunge from the 71% who said they used the social network in Pew’s previous study in 2015, when it was the dominant online platform.

In this year’s study reported Facebook use was, according to Pew, “notably lower” than the percentage of teens who said they used YouTube (85%), Instagram (72%) or Snapchat (69%). In the previous study, just 52% of teens said they used Instagram, while 41% said they used Snapchat. YouTube was not included in the 2014-2015 survey.
