Facebook disclosed on Monday that it has 901 million users, making it likely that it will pass the 1 billion mark well before the end of the year.

The company, which dropped the stat in its amended S-1 filing, also notes that its network receives 3.2 billion comments per day and 300 million new photos daily. The site also claims 125 billion friendships. Of the 901 million figure, 526 million were described as daily active users in March. Some 488 million people also used Facebook mobile products that month, according to the filing.

When Facebook filed its IPO paperwork with the SEC in February, the network tallied 845 million users. Back in January, Gregory Lyons, a senior analyst at iCrossing, estimated that Facebook would hit 1 billion users by August, a rate of growth that appears plausible based on the latest numbers.

Even before Monday’s latest numbers dropped, Facebook was by far the largest social network in the world. Twitter, which passed 500 million users in February, is number two on the list — although Twitter says that only 140 million of those accounts are active.
