Demographic Transition
The phenomenon of
population changes in a
country over time.
4 Stages:
1. Pre-transition
2. Early transition
3. Late transition4. Post transition

Pre-transitionStage One
Increase in birth and death rate
Result: little/no population increase

Examples
Countries such as Chad, Mali, (sub-Saharan) were the most
recent countries to evolve from the Pre-Transition stage
All countries and areas of the world were once Pre-
transitional.

Early transitionStage Two
Decrease in death rate and increase in birth rate
Result: Population increase
7/27/2019 Demography Presentation FINAL
12/20
Early Transition
This population increase was mainly caused by: Theimprovements in public health, water quality,improvements in sewage systems all caused by theindustrial revolution

Examples of Early Transition
The following graph shows the population in Angola for theyear 2005. It is between pre and early transition. The birthrate is still very high but many children are dying at a youngage. Also the graph
Demonstrates that people are not living to be very old

Late transition(stage Three)
Decrease in birth and death rate
Result: Population decrease
7/27/2019 Demography Presentation FINAL
15/20
Late transition
Push the
population into
stability through
declining birthrates.
Changes in death
rates are primarily
due to the changein a population.
7/27/2019 Demography Presentation FINAL
16/20
Post-transition(stage four)
The birth rate is relatively equal to the death rate
Result:
A general stabilization of the population

17/20
Definition
Stage 4- Post Transition-when populations reached
similarly low birth and death rates so that
populations would become essentially stable
