This is from a Pew Research Center study
Teens, Social Media and Technology 2024
Nearly half of U.S. teens (46%) say they're on the internet almost constantly. YouTube, TikTok, Instagram and Snapchat remain widely used by teens.

YouTube is the most used social media app for teenagers (Not sure YouTube is social media though) I hope the 90% of teens that are going on YouTube daily are doing the productive things I mentioned.
