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.
Sex-selective abortion
In addition, in many developing countries there are problems with birth registration and data collection, which can complicate the issue. With regard to the prevalence of sex selection, the media and international attention has focused mainly on a few countries, such as China, India and the Caucasus, ignoring other countries with a significant sex imbalance at birth. For example, Liechtenstein's sex ratio is far worse than that of those countries, but little has been discussed about it, and virtually no suggestions have been made that it may practice sex selection, although it is a very conservative country where women could not vote until 1984. At the same time, there have been accusations that the situation in some countries, such as Georgia, has been exaggerated. In 2017, Georgia' sex ratio at birth was 107, according to CIA statistics.
