Uncovering and explaining how our digital world is changing — and changing us.

Why are media companies and advertisers clamoring to work with Snapchat? Because media companies and advertisers are trying to track down the elusive Young People of America, who are increasingly hard to find in places they used to congregate, like in front of TVs.

And media companies and advertisers think they can find those young people at Snapchat.

This data from comScore will bolster that idea: The audience research company says that 71 percent of Snapchat’s American users fall in the 18-34 range. And it says 45 percent of Snapchat’s users are 18 to 24 years old. (Good hunch: Snapchat’s audience skews even younger than that, since comScore’s survey ignores everyone under the age of 18.)

What would those numbers look like if you put them in a chart and compared them to competitors like Vine, Facebook, Instagram and Twitter? Glad you asked:
