Facebook is now a mobile company, so the chart above points out a pretty major hole—and opportunity—for the social network. The social network’s monthly active user (MAU) base in most parts of the planet (particularly in Europe and North America) basically matches the number of smartphones available in those areas.
The glaring exception is Asia, which also happens to be the largest smartphone market on the planet. Facebook’s monthly active users in Asia equate to less than half of smartphone users there. Even when existing WhatsApp users are added in, there’s plenty of room to grow in Asia’s mobile space.
Of course, the discrepancy is partly explained by Facebook’s absence from most of China. The relatively low percentage of Asian users may also help explain why Mark Zuckerberg wants to bring free internet using drones to places like the Philippines.
