The United Nations is projecting that by 2100 there will be 10.1 billion on the planet. Africa’s population will triple rising from one billion to 3.6 billion. The report, containing this news, was released on Tuesday. Here are some of the highlights and implications for the African continent, as reported by The New York Times:

The projections were made by the United Nations population division, which has a track record of fairly accurate forecasts. In the new report, the division raised its forecast for the year 2050, estimating that the world would most likely have 9.3 billion people then, an increase of 156 million over the previous estimate for that year, published in 2008.

… In Nigeria, the most populous country in Africa, the report projects that population will rise from today’s 162 million to 730 million by 2100. Malawi, a country of 15 million today, could grow to 129 million, the report projected.

… One message from the new report is that the AIDS epidemic, devastating as it has been, has not been the demographic disaster that was once predicted. Prevalence estimates and projections for the human immunodeficiency virus made for Africa in the 1990s turned out to be too high, and in many populations, treatment with new drug regimens has cut the death rate from the disease.

… Other factors have slowed change in Africa, experts said, including women’s lack of power in their relationships with men, traditions like early marriage and polygamy, and a dearth of political leadership. While about three-quarters of married American women use a modern contraceptive, the comparable proportions are a quarter of women in East Africa, one in 10 in West Africa, and a mere 7 percent in Central Africa, according to United Nations statistics.

“West and Central Africa are the two big regions of the world where the fertility transition is happening, but at a snail’s pace,” said John F. May, a World Bank demographer.

Some studies suggest that providing easy, affordable access to contraceptives is not always sufficient. A trial by Harvard researchers in Lusaka, Zambia, found that only when women had greater autonomy to decide whether to use contraceptives did they have significantly fewer children. Other studies have found that general education for girls plays a critical role, in that literate young women are more likely to understand that family size is a choice.
