Breaks out domestic data and for the U.K.

Facebook would like advertisers in the United States and Britain to have a better idea of its platform's reach is in those countries, so it's self-reporting its mobile and Web users from June. The tech giant said on Tuesday that such data-points had not been previously released.

Per an email from a rep for the Menlo Park, Calif.-based firm, it totaled 142 million mobile active visitors in June in the U.S., including 101 million daily active users. In terms of the former stat, it reveals that roughly 17 percent of Facebook's monthly mobile audience consists of Americans.

In terms of the Web, Facebook accrued 179 million monthly active users during June in the U.S. as well as 128 million daily active users. For the daily data-point, that's 18 percent of its 699 global daily active users.

Meanwhile, here are numbers from the U.K.:

-Web monthly active users: 33 million

-Web daily active users: 24 million
