Facebook now has more than 900 million monthly active users and more than 500 million mobile users, according to an update to its IPO filing. More than half of those active users come back every single day.
The social networking giant also revealed it generated just over $1 billion in revenue in the first quarter of 2012, up 45% from one year ago but down 6.5% from the previous quarter. Advertising made up 82% of Facebook's revenue in the first quarter.
900 million users means one in eight humans on Earth have an active Facebook account. Facebook generates a little under $5 in revenue per user per year.
Facebook sees 300 million photo uploads every single day, the updated filing states, and the site now hosts 125 billion friendships. Users "like" and comment more than three billion times per day.
