Your source says 50%. Still higher than I thought. I’m wondering what are the numbers for insta

That 53% number meant that 53% of Snapchat's American users are 15-25, not that 53% of 15-25-year-olds in the US use Snapchat. Scroll down a little further to see that 78% of Internet users between 18 and 24 years old use Snapchat.
