Nigeria, often hailed as the world’s most prominent black nation has been projected to emerge the third most populous country in the world by the year 2100.
Population projections are attempts to show how the human population statistics might change in the future.
The report by the United Nation projected that the world population, 8 billion as of 2023, would peak around 2086 to about 10.4 billion, start a slow decline, assuming a continuing decrease in the global average fertility rate from 2.5 births per woman during the 2015–2020 period to 1.8 by the year 2100, (the medium-variant projection).
According to the UN, of the predicted growth in world population between 2020 and 2050, all of that change will come from less developed countries, and more than half will come from sub-Saharan Africa.
Half of the growth will come from just eight countries, five of which are in Africa. It is predicted that the population of sub-Saharan Africa will double by 2050.
The population of a country or area grows or declines through the interaction of three demographic drivers: fertility, mortality, and migration.
The list below shows the bulk of the world’s population growth is projected to take place in Africa.
