The last time Facebook announced its total worldwide traffic, it said it had 400 million monthly active users. That was February, three months after it said it had reached 350 million.

These traffic announcements may happen irregularly, but we’ve been tracking them all the way back to the company’s founding. As you can see from the graph below, growth has been consistently up and to the right.
