World Population Milestones

8 Billion (2023)

9 Billion (2037)

10 Billion (2057)

Explanation

In 2017 the UN predicted a decline of global population growth rate from +1.0% in 2020 to +0.5% in 2050 and to +0.1% in 2100.

Total inhabitants of an area at a given time is termed as Population

Explanation

Sub-Saharan Africa is the poorest part of the world.

The total fertility rate is near 4.8 children per woman.

Life expectancy is only 56 years old for males and 62 years for females.
