Nigeria has been projected to emerge the third most populous country in the world by the year 2100.
In a report by the United Nation, the world population, which is 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 UN projects that the population of Nigeria will surpass that of the United States by about 2050.
Population projections are attempts to show how the human population statistics might change in the future.
