Countries need a fertility rate of about 2.1 kids per family to maintain a stable population. But two-thirds of the world's population already lives in countries where fertility is below this so ...
Population momentum impacts the immediate birth and death rates in the population that determine the natural rate of growth. However, for a population to have an absolute zero amount of natural growth, three things must occur. 1. Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility ...
