The poorest economies may still be stuck in a ‘Malthusian
Trap’:
“While the average annual rate of natural increase –
births minus deaths - of the least developed countries is 2.5 percent, the
rates among some of the poorest countries are in excess of 3 percent, which
translates into a population doubling time of less than 25 years. Most of this
growth is in Africa: The populations of Burundi, Chad, Niger, Somalia and
Uganda, for example, are expected to double by 2040. The countries projected to
increase at least fivefold by 2100 include Angola, Burundi, Democratic Republic
of Congo, Malawi, Mali, Niger, Senegal, Somalia, Uganda, Tanzania and Zambia.”
