Global Fertility Differentials and the Demographic Divide Between Regions

Quick fact

Today, the average woman in sub-Saharan Africa has about 4.7 children, while in Europe the average is just 1.5—far below the 'replacement level' of 2.1 needed to keep a population stable. This 3-child gap is at the core of the global demographic divide.
