Global Mobile Phone Facebook Users, 2013-2018 [CHART]

Nearly 1 billion Facebook users worldwide will access the social network on a mobile phone at least once each month in 2015, according to a new forecast from eMarketer, which for the first time breaks out mobile phone Facebook users by country.

Over 70% of all Facebook users globally will be mobile this year, and by 2018, more than three-quarters of the social network’s audience will access the platform via mobile phones on a regular basis, totaling 1.34 billion users.

It’s no secret that mobile has been the key driver of growth in Facebook’s advertising business in the past 12 months. In 2013, 45.0% of Facebook’s $6.99 billion in advertising revenues worldwide came via mobile ads. This year, mobile ads will account for 73.0%—or $10.90 billion—of the social network’s ad revenues worldwide, eMarketer estimates. Read the rest at eMarketer.
