Facebook now has one billion active members, with users who access the service through a mobile device numbering 600 million.
In total there are 140.3 billion ‘friendships’ on the social network, with 1.13 trillion ‘likes’ and 219 billion photos having been uploaded.
In a statement, Mark Zuckerberg, who founded the social network in 2004, said: “Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life.
“I am committed to working every day to make Facebook better for you, and hopefully together one day we will be able to connect the rest of the world too.”
The service has seen a recent rise in mobile users of nearly 50 million since June, with 100 million new members having joined-up in total during the same period.
Facebook has admitted in the past that it faces a challenge in monetizing its mobile membership, with much of its business model being based around advertising. Since its headline-grabbing stock market flotation in May the value of Facebook shares has dropped to around half of the original price.
The firm has recently launched a test scheme in the US that will see ads appearing on its mobile apps targeted using data gathered from member profiles.
