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


8/20

Pre-transitionStage One

Increase in birth and death rate

Result: little/no population increase


9/20

What is pre-transition?

The pre-transition stage is when families in oneregion have much shorter life expectancy and largefamilies.


10/20

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.


11/20

Early transitionStage Two

Decrease in death rate and increase in birth rate

Result: Population increase


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


13/20

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


14/20

Late transition(stage Three)

Decrease in birth and death rate

Result: Population decrease


15/20

Late transition

Push the

population into

stability through

declining birthrates.

Changes in death

rates are primarily

due to the changein a population.


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
