Facebook passes 1.65 billion monthly active users, 54% access the service only on mobile

In its first quarter 2016 earnings announcement today, Facebook revealed it now has 1.65 billion monthly active users (up 15 percent year over year) and 1.51 billion mobile users (up 21 percent year over year). The company also shared that it now has 1.09 billion daily active users (a 16 percent bump year over year) and 989 million mobile daily active users (a 24 percent increase year over year).

Once again, Facebook has managed to keep all its numbers growing, albeit slowly, even on a quarter-over-quarter basis. Facebook’s total monthly active user base grew 3.77 percent in the first quarter.

Breaking the numbers down, 66.1 percent of all Facebook members use the service daily, and 65.5 percent of mobile members use it daily as well. Furthermore, 54.2 percent of Facebook users now access the social network exclusively from a mobile device.

Last quarter, Facebook passed the halfway mark for mobile-only users (51.7 percent to be exact). And that number continues to grow, according to the earnings slides (PDF) released today.

Between Q4 and Q1, Facebook added 71 million mobile-only users. This number climbs every quarter, though it will naturally slow down soon.

Here is how Facebook describes this category of users:

Mobile-only MAUs are defined as users who accessed Facebook solely through mobile apps or mobile versions of our website, or used our Messenger app, in the last 30 days of the given quarter. The number of mobile-only MAUs do not include Instagram users unless they would otherwise qualify as such users based on their other activities on Facebook.

Facebook doesn’t break out this number in its earnings release, but we watch for it every quarter. Even as the social network’s growth slows due to its size, the revenue share coming from mobile is still growing. In fact, Facebook shared that in Q1 2016, mobile ads accounted for 79 percent of all revenue.

Here are the other four charts for the numbers Facebook traditionally highlights in its releases:
