The Demographic Transition Model
Objective: Identify specific societal changes occurring in different stages of
demographic transition.
What is it? Model of population change based
on the effects of economic development
Based on the experience of how development happened in the Western World
All countries pass through 4 stages that lead them to a state of maturity
What does it look like?
Stage 1- preindustrial/preagricultural
Associated with pre-Modern times
Both birth and death rates are high resulting in slow population growth
What are the causes of high birth and death rates at this time?
Stage 2- improved agriculture and medicine Low death rates Infant mortality rate falls while
the birth rate remains high Rate of natural increase is high Why do death rates decrease?
Without demographic transition, we would not have seen this pattern
Stage 3Indicative of richer, more developed countries
Higher standards of living and
education
Crude birth rate finally falls
Stage 4
Birth and death rates have both stabilized
Population gets older
Population stabilizes
Example Countries
Problems with the Demographic Transition
Model
• based on European experience, assumes all countries will progress to complete industrialization• many countries reducing growth rate dramatically without increase in wealth• on the other hand, some countries “stuck” in stage 2 or stage 3
