It's no secret that social media is massively popular among today's youth but perhaps you'd be surprised to learn that a staggering 81 percent of teens between the ages of 12 and 17 use some form of social media. Of those, 94 percent said they have a Facebook profile according to a recent survey from the Pew Internet & American Life Project with the help of Harvard's Berkman Center.

Facebook outpaces all other social media accounts in use by teens by a huge margin, something that network size clearly reflects. Around half of teen Facebook users have 300 or fewer friends while 44 percent claim to have more than 300 friends. The average number of Facebook friends, according to the report, is more than 425.

Among those that use social media, only 26 percent said they had a Twitter account but it's a healthy increase from just 12 percent the previous year. Instagram is also on the rise with 11 percent saying they use the photo sharing service. For comparison, there apparently wasn't even enough data to report a year before (or Pew simply didn't measure that service in 2011).

YouTube and Tumblr also saw modest gains of one percent and three percent, respectively. The prospect for all other services, however, is dismal.

Unsurprisingly, MySpace saw the largest dropoff of teens over the course of a full year. 24 percent of social teens used the service in 2011 but only seven percent said they actively used it in 2012. Usage of Yahoo also dropped from seven percent to just two percent, although it's unclear exactly which service Pew is referring to specifically.
