On Oct. 4, Facebook hit a major milestone. CEO Mark Zuckerberg reported that the social media network now boasts more than 1 billion monthly active users. To put that in perspective, that’s approximately one-seventh of the world’s population. The median age for users who signed up in the week before hitting the big number was 22, with the most users in the U.S., Mexico, Indonesia, Brazil and India. Some other fun facts were revealed as well, such as, there have been 1.13 trillion Likes since the feature launched in 2009, 140.3 billion friend connections, 219 billion uploaded photos and 17 billion location-tagged posts.
