EYES ON THE SCREEN: 92% of teenagers go online every day, according to a study from the PEW Foundation which surveyed over 1,060 individuals ages 13-17--and a quarter self-report as being online “almost constantly.” That number is higher for African-American teens (34%), who also are more likely to have access to a smartphone than their Hispanic or white peers. The report also offers insights into the social media habits of teens, 71% of whom use more than one social networking site, with Facebook leading the pack--although more affluent teens tend to prefer Snapchat and Twitter.
