When this happened the births per woman went down from about 6 to around 2 in only ten years (Michigan U). The age distribution of developed countries is close to equilibrium due to the economic constraints. This means there are less young people to produce off spring, slowing the overall growth. In developing countries the age distribution is shaped like a pyramid, meaning many young people in turn causing more off spring and high populationShow MoreRelatedCauses and Effects of Overpopulation3400 Words   |  14 Pages| | The Population Explosion: Causes and Consequences by Carolyn Kinder Yale-New Haven Teachers Institute (2012) Until recently, birth rates and death rates were about the same, keeping the population stable.
