45% of young say they are online "almost constantly"

Recode - Some 45 percent of American teens say they are online “almost constantly,” according to a new survey from Pew Research. That number has nearly doubled from the 24 percent who said they were always online in Pew’s 2014-2015 study.

The results varied by gender. Fifty percent of girls said they were always online compared with 39 percent of boys.

What are they doing with all that time online? Mostly using Snapchat and YouTube. Thirty-five percent of teens said they use Snapchat most often out of any internet platform, while 32 percent used YouTube most often. At 15 percent, Instagram was the third-most popular online platform among teens.
