Define the demographic transition model and give one short worked example.

# Demographic Transition Model (DTM) ## Definition The Demographic Transition Model is a theoretical framework that describes the transition of a population from high birth and death rates to low birth and death rates as a country develops economically. It typically consists of 4-5 stages, with changes in population growth driven by industrialization, urbanization, and improved living standards. ## The Stages: 1. **Stage 1**: High birth rates, high death rates → stable/slow population growth 2. **Stage 2**: High birth rates, falling death rates → rapid population growth 3. **Stage 3**: Falling birth rates, low death rates → slowing population growth 4. **Stage 4**: Low birth rates, low death rates → stable/declining population growth 5. **Stage 5** (sometimes): Very low birth rates, low death rates → population decline ## Worked Example: **Japan** **1950s-1960s (Stage 2-3)**: - Death rates fell due to improved healthcare and nutrition - Birth rates remained relatively high - Result: Rapid population growth **1970s-1990s (Stage 3-4)**: - Birth rates declined as women entered workforce and urbanization increased - Death rates remained low - Result: Slowing population growth **2000s-Present (Stage 5)**: - Birth rate (~1.3 children per woman) below replacement level - Low death rate with aging population - Result: Population decline and aging crisis
