AdWeek illustrated some great data recently published by Pew Research Center, the first of its kind study that analyzes social media use by various demographics. A strong majority of internet users, 67 percent, are active on social media platforms like Facebook, Instragram and twitter. Yet, who and how social media is used varies greatly from groups to group. Twitter is popular with internet users 18-29 and Hispanics and blacks. Instagram is particularly appealing to Hispanics, blacks and women.. Though I published the results of the survey a few weeks ago, this infographic was too good, that I had to share.
