The demographic transition model LO: 1.Define birth rate, death rate and natural increase 2. Draw and annotate Demographic Transition Model and include relevant examples

Key terms: Birth rate: The number of live births per 1000 people per year Death rate: The number of deaths per 1000 people per year Natural Increase: The growth in population resulting from an excess of births over deaths

What is the DTM? L35nkkhttps:// L35nkk Starter: Spend a minute watching the video on the DTM to the left noting down the following in your books. a. What is the DTM? b. How many stages? c. How many lines? d. What do the lines show? e. What are the limitations?

What is the Demographic Transition Model (DTM)? The demographic transition model explains the transformation of countries from having high birth and death rates to low birth and death rates. In developed countries this transition began in the 18th century and continues today. Less developed countries began the transition later and many are still in earlier stages of the model.

Create your own DTM Watch the video again (or use a textbook if you would prefer): Complete your own DTM 1. The DTM has three lines - draw them on the model 2. Add the three lines to the key - on the right - with the correct titles. 3. Label each of the stages. 4. Label the two axis.

Why do the changes happen? 5iVeSQhttps:// 5iVeSQ Annotate your diagram to explain why the changes happen -Why does the death rate fall? -Why does the birth rate fall? -What do the changes do to the natural increase?

The table shows comparative birth rates, death rates and population-growth rates in some LEDC and MEDC countries:

Population growth in LEDCs

Population change in MEDCs Birth rates in MEDCs are falling as women choose to have smaller families later in life. Contraception is easily available and well understood. This helps women to plan their families and to have a career too

Thinking through geography… 1.Billy White loses his job as a gravedigger. 2.Parents are now able to plan how many children they will have. 3.Children share one bedroom with their brothers and sisters. 4.There are more wedding anniversaries for couples married for 50 years. 5.A mother cries at the grave of her sixth child who has died of the disease typhoid. All of her children have died. 6.A lot more houses are being built. 7.The public health inspector smiles as the building of new drainage systems for sewage( waste material from toilets) is finished. 8.Fewer children share a bedroom with their brothers and sisters. 9.Not many grandparents alive. 10.People are encouraged to leave their home countries and settle in other lands. Read the statements and tick the box that fits what each statement describes….Birth Rate (B/R), Death Rate (D/R) or Population Change (P/C). b. Place these statements on the best place on the demographic transition model- JUSTIFY why you have placed the statement where you have.

To finish… ‘DTM’ You are about to watch a clip on the DTM. It will summarise what we have learnt today. Towards the end is a quick quiz. Write the answers in your book.

Map to show Natural Increase 1.Describe the pattern shown on the map (4) General overview Use key Name areas Anomalies? 2. Explain why this pattern may occur (4) Mention an area with high natural increase and no change or loss

Explain why this pattern (natural increase) may occur (4) Must be linked to natural increase- so include both birth and death rates Areas such as Africa tend to have a high natural increase because there death rates are falling (due to medical advancements and improving access to essential services such as water) but their birth rate remains relatively high due to lack of contraception/ low status of women etc. This leads to an natural increase. In MEDCs the birth rate has fallen (due to high cost of living and later marriage etc.) which means that the birth rate and death rate are roughly equal meaning no or less increase in the total population.
