- The Demographic Transition Model (DTM) illustrates how birth rates, death rates, and population change over time as a country develops.
- Stage 1: Both birth and death rates are high, resulting in slow population growth.
- Stage 2: Death rates fall rapidly due to improvements in healthcare and sanitation, while birth rates remain high, causing rapid population growth.
- Stage 3: Birth rates begin to decline as a result of urbanization, increased access to education, and family planning, leading to slower population growth.
- Stage 4: Both birth and death rates are low, resulting in a stable or slowly growing population.
- The green line represents total population, which rises sharply in Stage 2 and levels off in Stage 4.
- The purple line is the birth rate, which starts high and gradually declines across stages.
- The red line is the death rate, which drops sharply in Stage 2 and remains low thereafter.
- The model was developed by Warren Thompson in 1929 to describe demographic changes in industrialized societies.
