Facebook as of today, has 1.01 billion active users on its network. In the social network's Quarter 3 earnings report, it revealed that in September 2015, the number of daily active users on the network clinched the 1.01 billion mark.

The world's population is estimated at 7 billion people, and Facebook has an active number of 1.01 billion users - that automatically means one-seventh of the world's population populate Facebook. Well done Mark!

Facebook's sister network, Instagram, has 400 million active users to its name - that's also something.
