The populations of nonindustrial countries are normally stable (and low) because high birth rates are matched by high death rates.  By 2009, the existence of a negative correlation between fertility and industrial development had become one of the most widely accepted findings in social science..

Hence, the age structure of the population becomes increasingly youthful and start to have big families and more of these children enter the reproductive cycle of their lives while maintaining the high fertility rates of their parents. First, improvements in the food supply brought about by higher yields in agricultural practices and better transportation reduce death due to starvation and lack of water.
