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.
Childbirth in Japan
Women's health related figures in Japan are inspiringly positive. Japan boasts one of the longest life expectancies for women in the world at 82.25 years. According to WHO statistics, life expectancy rate were 83 for both sexes and 86 for women in 2011. And the infant mortality rate is 2.78 deaths per 1,000 live births, one of the lowest in the world. Whether these two facts are related to a final figure, the 2011 estimate of fertility rate of just 1.21 children, is as yet undetermined. Infant mortality rate has decreased to 2.13 per 1,000 live births in 2014. Maternal mortality rate is 5 deaths per 100,000 live births, one of the lowest in the world
