Facebook is announcing that it now has 2 billion monthly users around the world, a new record for the giant social network.

The milestone comes 13 years after the company first launched, and 5 years after it hit the 1 billion-mark.

Literally, Facebook is bigger than the population of any single country, and of six of the seven continents. It represents more than a quarter of the world’s 7.5 billion people.

Speaking on the announcement, Facebook CEO Mark Zuckerberg wrote on his page:

“As of this morning, the Facebook community is now officially 2 billion people! We’re making progress connecting the world, and now let’s bring the world closer together. It’s an honor to be on this journey with you.”

Facebook is some way ahead of its competition, with YouTube the closest at 1.5 billion users.

WhatsApp and Instagram — both owned by Facebook — have 1.2 billion and 700 million users respectively.

Twitter has 328 million users, while Snapchat has approximately 255 million users.

“We’re getting to a size where it’s worth really taking a careful look at what are all the things that we can do to make social media the most positive force for good possible,” Facebook Chief Product Officer Chris Cox told TechCrunch.

“There’s definitely a deep sense of responsibility in every part of the company,” Cox added. “We’re getting to the scale where we have to get much better about understanding how the product has been used.”
