Most people in the developing world do not use the Internet, with access limited by high costs, poor availability and a lack of relevant content, a Facebook report said Tuesday. Facebook, which carried out the study through its Internet.org initiative that aims to boost connectivity around the world, said the rate of growth on the Internet is slowing.
"By early 2015, three billion people will be online. This is an incredible milestone, but it also means that only 40 percent of the world's population has ever connected to the Internet," the report said.
In the developed world, some 76 percent of the population is online, but the figure is just 29.8 percent in developing nations, according to the research.
The rate of growth of Internet users was just 6.6 percent in 2014, the fourth year of deceleration.
"At present rates of decelerating growth, the internet won't reach four billion people until 2019," the report said.
The report said tech companies, governments and non-government organisations need to do more to boost the number of people online.
The report said the three main factors which keep people offline were lack of infrastructure, affordability and the lack of relevant content for people in their languages.
