Here on VDARE.com, a demographer points out that all my scary graphs lately have been based on the U.N. Population Division’s optimistic-sounding “medium fertility variant” in which total fertility rates magically converge toward 1.85 babies per woman by the end of the century.
But what if Africans just go on doing what comes natural? The correspondent points out that 10 billion is within reach under the assumption of constant fertility and mortality rates. Indeed, the UN offers a “constant fertility” table with, I believe, declining mortality due to technological advances in health care in which Sub-Saharan Africa’s population in 2100 is 15,175,708,000.
Fifteen billion Sub-Saharans is really not likely to happen, but my main point is: I’m not making these numbers up. These all come from the United Nations, not me.
Also, the UN offers a super optimistic “instant replacement fertility” table in which the total fertility rate drops to replacement today and remains that for the rest of the century. Due to demographic momentum, the population of sub-Saharan Africa still grows from 969 million in 2015 to 1,237 million in 2035 to 1,444 million in 2050 to 1,731 million in 2100.
