The latest global population estimate is 7.6 billion in mid- 2017. It is likely that we will reach 8 billion in 2025.

How is the world’s human populated by continents? In 2017, Asia, with 21 percent of the land has nearly 60 percent of humanity. Africa with 20.4 percent of the land has 16.5 percent of all humans. Europe including all of Russia has 15 percent of Earth’s land and 10 percent of humanity.
