The era of Facebook’s nonstop growth has long since come to an end. Although the company is far from the point at which it might start to shrink, its growth in the US and Canada, as well as Europe, has stopped entirely and appears to occasionally decline.

In its 2018 third quarter earnings report out today, the social network confirmed that the number of daily active users in US and Canada has remained flat at 185 million, while the number of European users has slipped from 279 million to 278 million. The latter may be a direct result of recent European privacy regulations, namely GDPR, which initially caused Facebook to lose 1 million monthly active users after it went into effect in May.
