User Count Shrank In Europe, Flat In US & Canada – Facebook saw its first-ever decline in monthly user count in Europe, from 377 million to 376 million. It got stuck at 241 million in the US & Canada after similarly pausing at 239 million in Q4 2017. Those are Facebook’s two most lucrative markets, with it earning $25.91 per user in North America and $8.76 in Europe. If those markets stall, even swift growth in the Rest Of World region where it earns just $1.91 per user won’t save it.
