Social Network Usage Share By Site & Age, December 2014 [CHART]

This year, 95.0% of 18-to-24-year-old internet users in the US will log on to a social network via any device at least once per month, eMarketer estimates—the highest penetration among any other age range. Based on recent research by comScore Media Metrix, Snapchat usage skews heavily toward this group.

According to the December 2014 study, internet users ages 18 to 24 accounted for 45% of Snapchat users in the US. Their older millennial counterparts—25- to 34-year-olds—had the second-largest share of users, though one nearly 20 percentage points lower, leaving the 35-and-older group with just 30% share. In comparison, for every other social network studied, young millennials didn’t even represent 30% of the audience. Read the rest at eMarketer.
