2 Key terms:Birth rate: The number of live births per 1000 people per yearDeath rate: The number of deaths per 1000 people per yearNatural Increase: The growth in population resulting from an excess of births over deaths

7 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.
14 What are the limitations? What limitations do you think there could be with the model?It does not include the influences of migrationIt assumes that all countries will go through the same patternThere is no time scaleReasons for birth rates and death rates are very different in different countries
15 The table shows comparative birth rates, death rates and population-growth rates in some LEDC and MEDC countries:
17 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 tooPopulation change in MEDCs
18 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
19 Write the answers in your book. 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.
