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.
Demographics of Niger
Niger's high infant mortality rate is comparable to levels recorded in neighboring countries. However, the child mortality rate (deaths among children between the ages of 1 and 4) is exceptionally high (274 per 1,000) due to generally poor health conditions and inadequate nutrition for most of the country's children. Niger's very high total fertility rate (6.89 children born per woman, which is the highest in the world), nonetheless, means that nearly half (49%) of the Nigerien population is under age 15. School attendance is low (34%), including 38% of males and 27% of females. Additional education occurs through Koranic schools.
