In all, the population of sub-Saharan Africa is expected to practically double by 2050, the report said.

The report has mentioned that the growth in population will come despite the slowing of the global fertility rate. In 1990, the average number of births per woman was 3.2. By 2019 this had fallen to 2.5 births per woman and, by 2050, this is projected to decline further to 2.2 births: a fertility level of 2.1 births per woman is necessary to avoid national population decline over the long run (in the absence of immigration).Further, life expectancy at birth for the world, which increased from 64.2 years in 1990 to 72.6 years in 2019, is expected to increase further to 77.1 years in 2050.
