Teenagers are more interested than ever in YouTube, home to the world’s growing influencer and vlogger base. According to a recent study conducted by Pew Research Center, 85 percent of teenagers (ages 13–17) say they use the platform. Closely behind are Instagram (72 percent) and Snapchat (69 percent).

Pew’s findings indicate an ongoing trend of teenagers moving away from platforms like Facebook in recent years. (It’s worth noting that Pew’s report in 2015 did not include YouTube or Reddit.) A 2015 report pointed to 71 percent of teens who reported themselves as Facebook users; today, that number is around 51 percent. “For the most part, teens tend to use similar platforms regardless of their demographic characteristics,” Pew’s report states, “but there are exceptions. Notably, lower-income teens are more likely to gravitate toward Facebook than those from higher-income households.”
