As of January 2017, the social media and World Wide Web giant Facebook claimed 1.79 billion active users.
Notice the descriptive adjective "active" was used there. This means these are Facebook accounts which show regular and continual activity. Only roughly 47% of the global population of 7.3 billion people use the Internet or 3.4 billion people.
In other words, more than half of everyone on the Internet, 52.65% to be exact, is regularly active on Facebook. Estimates show that Facebook users spend between 40 and 50 minutes of each day on FB.
