Demographic Transition Theory
Demographic Transition Theory describes how a country’s population changes as it develops economically. It typically follows four stages: 1. **High Birth and Death Rates**: Population grows slowly due to high mortality. 2. **Declining Death Rates**: Improved healthcare lowers deaths, causing rapid growth. 3. **Declining Birth Rates**: As families opt for fewer children, growth stabilizes. 4. **Low Birth and Death Rates**: Population levels off, leading to an aging society. Countries move through these stages, reflecting shifts in social, economic, and health conditions that shape family size and life expectancy. Understanding this helps policymakers address issues related to population growth and resources.

Demographic Transition Theory explains how a country's population changes over time as it develops economically. It typically progresses through five stages: 1. High birth and death rates lead to stable population. 2. Death rates decline due to improvements in healthcare, causing population growth. 3. Birth rates start to fall as people have fewer children, leading to slower growth. 4. Both birth and death rates are low, stabilizing the population. 5. Some countries experience a decline in population due to very low birth rates. This theory helps us understand population dynamics and development patterns across different regions.
