Study Notes
Demographic Transition Model (DTM)
- The DTM illustrates historical population trends through birth and death rates.
- It outlines how a country's total population growth shifts through distinct stages as it develops economically.
- Each stage reflects a unique relationship between the birth rate (annual births per thousand) and death rate (annual deaths per thousand).
- Countries progress through the model over time due to social and economic influences on birth and death rates.
- Not all stages of the DTM are currently represented by countries; for instance, there are no countries in Stage 1 or Stage 5 presently.
Stage 1
- Characterized by a low population growth rate due to high birth and death rates.
- High death rates often result from poor living conditions and lack of medical knowledge.
- Birth rates are elevated as families have more children to offset high mortality rates.
Stage 2
- Marked by a significant decline in the death rate while the birth rate remains high.
- Population increases rapidly since births outpace deaths.
- Improvements in sanitation, healthcare, and nutrition typically cause the drop in death rates.
Stage 3
- Features low death rates and declining birth rates.
- Economic improvement, increased women’s education, and better access to contraception contribute to decreased birth rates.
- Societal changes, such as urbanization, often impact family size preferences.
Stage 4
- Defined by both low birth and death rates, resulting in stable population growth.
- Societies in this stage often experience higher living standards and better healthcare systems.
- Family planning and individual lifestyle choices further affect birth rates.
Stage 5
- A theoretical stage where the death rate surpasses the birth rate, leading to negative population growth.
- This stage may result from aging populations and societal shifts towards smaller families.
- Immediate effects of this stage may not be evident, suggesting gradual changes over time.
Population Pyramid
- A visual representation showing the age-sex distribution within a population.
- Used to analyze demographic trends and predict future population characteristics.
- Helps identify potential growth patterns, workforce size, and social needs based on age cohorts.
