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.
Crime in the United States
According to a 2001 report from UNICEF, the United States has the highest rate of deaths from child abuse and neglect of any industrialized nation, at 2.4 per 100,000 children; France has 1.4, Japan 1, UK 0.9 and Germany 0.8. According to the US Department of Health, the state of Texas has the highest death rate, at 4.05 per 100,000 children, New York has 2.46, Oregon 1.49 and New Hampshire 0.35.  A UNICEF report on child wellbeing stated that the United States and the United Kingdom ranked lowest among industrial nations with respect to the wellbeing of children.
