The Demographic Transition Model
Based on experiences of Britain, and it can be used as a predictive model to show what may happen in developing in industrialising countries. Particularly strong as a descriptive model but less strong as a predictive model.
- Dynamic, showing changes through time.
- Shows what has happened in UK
- Other countries when industrialising went through similar stages.
- Newly industrialising countries are going through stages at a much faster rate.
- Helps to explain what has happened and why.
- Based on experiences of industrialising countries, so cannot be relevant non-industrailisng countries.
- Assumes stage 2 follows from industrialisation, but in many cases this is not the case.
- As well it assumes stage 3 followed decade after stage 2, and that the death rate fell as a consequence of changes brought by changes in the birth rate.
- Original Model has had to adapted to include a fifth stage.
- Countries in Africa have slipped back into Stage 1, because of HIV/Aids, and model does help to predict the future of these countries.
