The Demographic Transition Theory

The Demographic Transition Theory describes how populations change over time as a society develops. It typically progresses through four stages: 1. **Pre-Transition**: High birth and death rates, leading to a stable population. 2. **Transition**: Death rates drop due to improved healthcare, while birth rates remain high, causing population growth. 3. **Mature Transition**: Birth rates begin to fall as people have fewer children, leading to slower population growth. 4. **Post-Transition**: Both birth and death rates are low, resulting in an aging population and stable or declining numbers. This theory helps explain population changes in relation to economic and social development.
