Birth rate
The region of Sub-Saharan Africa has the highest birth rate in the world. As of 2016, Niger, Mali, Uganda, Zambia, and Burundi have the highest birth rates in the world. This is part of the fertility-income paradox, as these countries are very poor, and it may seem counter-intuitive for families there to have so many children. The inverse relationship between income and fertility has been termed a "demographic-economic "paradox"" by the notion that greater means would enable the production of more offspring as suggested by the influential Thomas Malthus.
List of countries by number of births
The following list sorts countries by the total projected number of births. The list is sourced from the United Nations World Population Prospects. Figures are from the 2017 revision of the United Nations World Population Prospects report, for the period 2015–2020, using the medium assumption. All figures are rounded and given in thousands.
