Facebook revealed today that 78% of U.S. users are visiting the site from their mobile devices. The company announced today that it will start sharing country-by-country metrics about its daily and monthly active users, in a move to help advertisers have a better understanding of users.

According to Facebook, Facebook has 128 million daily users from the web and 101 million daily users via mobile. Facebook explained its new process in this statement:

We are doing this because we believe brands and businesses should think differently about how people engage with Facebook, especially on mobile. A lot of people focus on monthly active users or even registered users to demonstrate their size and scale. We think this is becoming on old way of looking at the media world. In this world, understanding who comes back at least once a month is only part of the picture. Instead, businesses should focus on people who come back online every single day.
