Facebook announced its Q4 2014 earnings today, revealing that 1.39 billion users now use the social network every month, which marks a 13% year over year growth.
Monthly active users on mobile grew even more at 26% year over year, now sitting at 1.19 billion in total.
Breaking it down even further, 890 million users access the service each day, which is up 18% from last year. Again, mobile saw greater growth in this area with 34% year over year growth, now sitting at 745 million daily active users.
The most remarkable thing about this report is the rate at which Facebook is growing in terms of people who access the network only on mobile.
From Q3 to Q4 Facebook added 70 million mobile-only monthly active users. Over half a billion users, 526 million to be exact, now access Facebook only on their mobile devices. In total, these mobile-only users represent 37.8% of all monthly active users.
Facebook’s growth on mobile is perfectly illustrated in the slides included with the earnings report, one of which is included at the top of this post.
These mobile users are also helping Facebook rake in a healthy percentage of ad revenue, representing 69% of Facebook’s $3.59 billion made in ad dollars.
When counting mobile users, Facebook includes users of the flagship app and the Messenger app, but not users of other apps the company owns such as WhatsApp and Instagram.
