Demographic Transition Model
a model of how the size of a population changes as a country develops its economy
Total population is low but it is balanced due to high birth rates and high death rates
Total population rises as death rates fall due to improvements in health care and sanitation. Birth rates remain high.
Total population is still rising rapidly. The gap between birth and death rates narrows due to the availability of contraception and fewer children being needed to work - due to the mechanization of farming.
Total population is high, but it is balanced by a low birth rate and a low death rate. Birth control is widely available and there is a desire for smaller families.
Total population is high but going into decline due to an aging population. There is a continued desire for smaller families, with people opting to have children later in life.
