What is the demographic transition model?

The demographic transition model is a theoretical framework that describes the historical and future changes in population patterns of a country or region. It consists of four stages: pre-industrial, transitional, industrial, and post-industrial. In the pre-industrial stage, birth and death rates are high, resulting in slow population growth. In the transitional stage, improvements in healthcare and living conditions lead to a decrease in death rates, while birth rates remain high, causing rapid population growth. In the industrial stage, birth rates start to decline due to urbanization, increased education, and access to contraception, resulting in slower population growth. Finally, in the post-industrial stage, both birth and death rates are low, leading to a stable or declining population.
