More than half of the world’s population will be online this year, according to new estimates released by the International Telecommunication Union and reported by the website Statista. The ITU estimates that about 3.9 billion users are set to go online as 2019 begins, up from 3.6 billion in 2017.

Statista’s Sarah Feldman noted that accelerating growth across the many nations in Africa are responsible for this continued uptick. In 2005, only 2 percent of people in Africa used the internet, according to the U.N. As of 2018, about a quarter of people in Africa used the internet.

Between 2005 and 2018, about four times more people across the world are on the internet.
