The document discusses the Demographic Transition Model (DTM) and population pyramids. It provides instructions to determine which stage of the DTM various population scenarios described in statements would fall under. It also discusses comparing population pyramids of less economically developed countries (LEDCs) and more economically developed countries (MEDC), how they vary in age and gender structure, and how this relates to development indicators and can change over time. Finally, it provides activities analyzing India's population structure through population pyramids and discussing overpopulation issues.

1. From memory: Demographic Transition Model
Can you remember what the pattern is like at
each stage? And the reasons for it?

2. Statement Which stage
on the DTM?
Why here? PROVE IT.
Jack realises there is not enough farmland available in his
village for everyone to grow what they need to survive.
He and his wife and 5 children migrate to another area
where there is fewer people & more land available.
Hospitals are overcrowded with high waiting lists due to
an increased demand for joint replacement surgery or to
treat geriatric illnesses.
Parents of children face difficulty placing their child in
schools close to home due to conflict and waiting lists to
attend a school of their choice.
Energy bills in winter rise each year due to pressure on
the energy grid to provide enough gas and electricity to
meet consumer demand.
The population remains reasonably steady despite
fluctuations in birth and death rate.
You must decide….
• Where on the Demographic Transition Model you would put each statement.
You must be able to…
• Justify your decision by referring to birth rates, death rates or population changes.
e.g. This is because birth rates are high but death rate is
falling so people live longer so natural increase is
occurring and exponential growth. This means there is not
enough farmland or resources because the total
population is now too high, with overcrowding.
Stage 2

3. What is this?

4. How and why does the age and gender
structure of populations vary?
Population Pyramids,
comparisons of LEDC’s v’s MEDC’s
and changes over time

6. So what are population pyramids?
