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.
Women in the Czech Republic
The maternal mortality rate in Czech Republic is 5 deaths/100,000 live births (as of 2010). The HIV/AIDS rate is 0.05% of adults (aged 15–49) - estimates of 2013. The total fertility rate (TFR) is 1.43 children born/woman (2014 estimates), one of the lowest in the world. As in many other European countries, family formation has become more liberal, unmarried cohabitation has increased and the connection between fertility and marriage has decreased in the past decades; as of 2017, 49% of births were to unmarried women.
