The demographic transition model outlines how a country's population structure and growth rates shift as it industrializes. early stage countries typically have very high birth rates, burdening their developing economies and societies. later stages see lower. It describes the five stages of demographic transition that countries generally progress through as they develop economically: (1) high birth and death rates; (2) declining death rates and high birth rates leading to population growth; (3) declining birth rates as well as death rates; (4) low birth and death rates as population growth. The theory of demographic transition describes the historical shift that societies undergo from high birth and death rates to low birth and death rates as countries develop economically and technologically. it outlines that pre industrial societies had high fertility and mortality, while industrialized countries now have lower rates of both.
