You know what's cooler than a million users? A billion users. And now Facebook has just that.

Yep, the social network birthed in a Harvard dorm grew in eight short years to a membership that it says accounts for nearly one-seventh of the world’s population. Not fake users or bots — which Facebook tracks closely — but real humans who actively engage on the social network, a company spokesperson told TODAY.

Just so we’re clear: As of Sept. 14, one in seven people on this planet has been classified by the company as an active Facebook user.

Facebook founder and CEO Mark Zuckerberg shared the milestone in an exclusive interview with Matt Lauer, which aired Thursday on TODAY.

"I mean, it's just — an amazing honor," Zuckerberg said of his social network’s monolithic membership when he sat down with Lauer last week at Facebook’s campus in Menlo Park, Calif. "To be able to come into work every day and build things that help a billion people stay connected with the people they care about every month — that's just unbelievable."

No hyperbole there. Since Facebook launched, the social network’s seen 1.13 trillion "likes" and 140.4 billion friend connections. 219 billion photos are currently being shared, while 17 billion check-ins have been made. Since the music listening app launched in September 2011, 62.6 million songs have been played 22 billion times — that's around 210,000 years of music.
