The demographic transition model is a theory that explains the population changes in a society over time. It consists of four stages: high birth and death rates in stage 1, decreasing death rates in stage 2, decreasing birth rates in stage 3, and low birth and death rates in stage 4.

Steps in the Demographic Transition Model:

1. Stage 1 - High Fluctuating: High birth and death rates, stable population.

2. Stage 2 - Early Expanding: High birth rates, declining death rates, rapid population growth.

3. Stage 3 - Late Expanding: Declining birth rates, low death rates, population growth slows.

4. Stage 4 - Low Fluctuating: Low birth and death rates, stable population.

5. Stage 5 - Declining: Very low birth rates, stable or declining population.

Each step represents changes in birth and death rates due to social, economic, and technological advancements impacting population growth.

Demographic Transition Models

Central Idea

• Demographic Transition Models

Main Branches

1. Stage 1: High Stationary

   • High birth rates

   • High death rates

2. Stage 2: Early Expanding

   • High birth rates

   • Declining death rates

3. Stage 3: Late Expanding

   • Declining birth rates

   • Low death rates

4. Stage 4: Low Stationary

   • Low birth rates

   • Low death rates

5. Stage 5: Declining

   • Very low birth rates

   • Low death rates

Sub-branches

• Factors influencing each stage

• Impacts on population growth

• Policy implications

  Pros and Cons of Using the Demographic Transition Model:

  Pros:

  • Helps understand population changes over time

  • Guides policy-making and resource allocation

  Cons:

  • Assumes linear progression

  • Ignores cultural and social factors influencing demographics
