Facebook has the most global members of any social network, but YouTube has the most monthly visitors, according to a recent report from Global Web Index.
The report was based on data from Global Web Index's panel of Internet users age 16-64 from 31 countries (China excluded). Panelists were asked about their habits on four major social networks: Facebook, Twitter, YouTube, and Google+.
Some 81% of panelists are Facebook members, the most of any of the four social networks examined. Facebook also has the highest percentage of active users (42% of panelists).
However, YouTube has the most monthly visitors (i.e., people who do not necessarily log in) of the four networks. Some 82% of panelists say they visited YouTube in the previous month.
