A. Billy White loses his job as a grave digger.

C. Children share one bedroom with their brothers and sisters.

D. There are more wedding anniversaries for couples married for 50 years.E. A mother cries at the grave of her sixth child who has died of the disease typhoid. All of her children have died.

F. A lot more houses are being built.

H. Fewer children share a bedroom with their brothers and sisters.

I. Not many grandparents alive.

J. People are encouraged to leave their home countries and settle in other lands.

Make an estimate for birth rate / death rate / population change by using the DTM graph.

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.

In teams of 3, 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.
