In honor of Facebook’s 10th birthday, I’ve made a graphic on multi-platform social media use. The data, from a Pew Research Center study published at the end of 2013, show that Facebook still has a dominant presence in the social media world. Of the five social media platforms considered, at least 83% of people who use the other platforms also use Facebook. Twitter and Instagram users are the most likely to have accounts with more than one social media platform.
