This year, 2.46 billion individuals, or one-third of the global population and 71.0% of internet users, will access social networks at least once a month, up 8.2% from 2016. Mobile phone adoption and expanding mobile coverage will drive that growth.
Most user growth will be driven by the widespread availability of affordable smartphones, accessible Wi-Fi coverage and expanding 3G and 4G networks. Individuals taking advantage of these developments in Asia-Pacific, Latin America and the Middle East and Africa will largely be new internet users who are signing up for social media for the first time. In 2017, 81.8% of social network users worldwide will log on via a mobile phone. By 2021, that share will grow to 86.7%.
