Inside Facebook

Facebook said yesterday that a small bug recently appeared in the Developers console that caused some applications to show incorrect total user numbers. However, the stats should be fixed as of today.

It’s worth noting that the total user metric is not outward facing. This metric is different from the Monthly Active Users metric that Facebook publicizes which reports the number of active, engaged users over a 30 day period. The Total Users metric tracks how many individual users have authorized an application overall.
