1. What is it and why is it important?

2.  What is it?  What was it based on?

3. The High Fluctuating Stage This stage is typified by a high CBR and CDR. WHY? Population growth is very slow. WHY?

4. The Early Expanding Stage Stage 2 sees the death rate drop. CAUSES: Birth rate remains high. CAUSES: Population growth rates are skyrocketing. WHY? Considerable rural to urban migration takes place.

5. The Late Expanding Stage During stage 3 the total population is still rising rapidly, but the gap between birth and death rates narrows, why? Population growth in many stage 3 countries is due to what? Urbanisation slows.

6. The Low Fluctuating Stage Stage 4 the total population is high, but it is balanced, why? Birth rate fluctuates due to: Death rate rises slightly because: What happens to life expectancy?

7. The Natural Decrease Stage In Stage 5 the total population is high but going into decline, WHY? Which countries are entering Stage 5? For there to declining population there has to be an absence of what?

8. DTMUses Simplifies the real world Predict future trends PlanningAdaptabilityLimitations Failed to predict population decline Assumes that in time all countries will pass through the same four stages. Unlikely that many LEDCs will ever become industrialised Doesn’t account for many factors Inability to afford medical facilities Religious influence Political influence Impact of epidemics Migration

9. As countries progress through the DTM, fertility rates fall – however, the population can continue to increase. This phenomenon is known as DEMOGRAPHIC MOMENTUM.

High death rate.Falling death rate.Low death rate. Short life expectancy. Slightly longer life expectancy. Long life expectancy. Longer life expectancy. Rapid fall in each upward age group due to high DR. Fall in DR so more people living into middle age. An increasing proportion of the population is in the 65+ age group. Higher dependency ratio.
