What is The Demographic Transition Model?
Within Geography, which covers maps, landforms, weather, climate, population and settlements: understand how our planet and people connect, this topic explains The Demographic Transition Model. Geography explains how places, people and natural processes connect, so each topic here combines a clear definition with a visual model.
Check that you can explain The Demographic Transition Model in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding The Demographic Transition Model helps you explain patterns on maps and in the news, and make reasoned decisions about places and environments.
The Demographic Transition Model in detail
The Demographic Transition Model (DTM) shows how a country's birth rate, death rate and total population change as it develops. In stage 1, birth and death rates are both high and population is stable. In stage 2, death rates fall because of better healthcare and food while birth rates stay high, causing rapid growth.
In stage 3, birth rates fall as people have access to contraception, education and opportunities for women, and growth slows. In stage 4, both rates are low and the population is stable or growing slowly. Stage 5 may have a declining population. The UK is in stage 4, and many African countries are in stage 2 or 3.
How the interactive helps you understand The Demographic Transition Model
Watch the growth curve in the interactive. Use any sliders or buttons it offers to change the values and see how the growth curve responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of The Demographic Transition Model.
