NEW YORK (AP) — Despite what you may have heard, the nation’s teenagers aren’t done with Facebook.

According to a new study from the Pew Research Center, Facebook is still the most used social media site among Americans ages 13 to 17. And boys visit the site more often than girls do.

With the help of smartphones and other mobile devices, 71 percent of teens who were surveyed said they use Facebook. The same percentage said they use more than one social network out of the seven options there were asked about.

Half the teens said they also use Instagram. Four in ten said they use Snapchat.

The study points to Facebook as a dominant force in teens’ online lives, even as Instagram and Snapchat have gained momentum.

As far as how much time is spent on social media, the study suggests that 24 percent of teens overall go online “almost constantly,” with 56 percent saying they go online several times a day and 12 percent reporting once-a-day use.
