From The Economist, September 22, 2018
In 2100.the population of Africa is projected to be 4 billion, for the Rest of World, 7 billion. The Africans don’t yet, or won’t by 2100, outnumber the rest of us, although if the new Africans are anything like the kids pictured below the world might be a better place for their being here.
But the lives these children. What will they be like? The current world population of 7.2 billion is projected to increase by 1 billion over the next 12 years and reach 9.6 billion by 2050, according to a United Nations report. The report points out that growth will be mainly in developing countries, with more than half in Africa.
According to the Economist article the 21st century, in one way at least, will be African. In 1990 sub-Saharan Africa accounted for 16% of the world’s births. Because African birth rates are so much higher than elsewhere, the proportion has risen to 27% and is expected to hit 37% in 2050. About a decade later, more babies will be born in sub-Saharan Africa than in the whole of Asia, including India and China. … There is good reason for the world to worry about Africa’s baby boom.
