Pew Research Centre surveyed more than 1,300 American teens ages 13 to 17 and found that Facebook use plummeted by nearly 40 per cent since the center's survey from 2014 to 2015.

Teens are apparently more interested in giving their data and short movies to TicTok with 67 per cent of responders saying they use TikTok and 16 per cent saying they use it nearly constantly.

YouTube is used by 95 per cent  of teens and Instagram and Snapchat are both used by about 60 per cent of teenagers.

In addition, 35 per cent of teens report they are using at least YouTube, TikTok, Instagram, Snapchat or Facebook "almost constantly."
