The neo-Malthusian controversy, comprising related debates of many years later, has seen a similar central role assigned to the numbers of children born.

Changes in values regarding children and gender play as significant a role as the availability of contraceptives and knowledge of how to use them.

The population structure becomes less triangular and more ...
