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.
Argentines
According to the , Argentina had a population of 40,091,359 inhabitants, of which 1,805,957 or 4.6%, were born abroad. The country has long had one of Latin America's lowest growth rates, estimated in 2008 to be 0.917% annually, with a birth rate of 16.32 live births per 1,000 inhabitants and a mortality rate of 7.54 deaths per 1,000 inhabitants. It also enjoys a comparatively low infant mortality rate. Strikingly, though, its fertility rate is still nearly twice as high (2.3 children per woman) as that in Spain or Italy, despite comparable religiosity figures. The median age is approximately 30 years and life expectancy at birth is 76 years.
