Replacement Population
Forget Fear of Overpopulation. Half the World’s Population Groups Are Declining
The UN estimates that almost half of the world's population lives in countries with below replacement fertility rates. The main clusters of low fertility generally are found in advanced and industrialized regions. The big story here is that all the hand-wringing over an overcrowded future planet is scientifically unfounded. If the current trend continues, it is even possible that mankind soon will be worried about population shrinkage and underproduction.
