1Starter – Factors affecting fertility rates List and explain the factors that affect fertility rates in different countries.HINT: Why do most MEDCs have fewer babies than LEDCs?EducationImproved healthFamily planningIncrease incomePolitical factors / government controlExpensive
2Learning outcomes You should all be able to: Identify the factors that affect fertility rates.Identify the components of age/sex pyramids and the demographic transition models.Most of you should be able to:Interpret the data from age/sex pyramids and demographic transition models to reach a conclusionSome of you might be able to:Discuss the use of models in predicting the growth of human population
3Age/sex pyramids?Look at these examples of age/sex pyramids and write down what they represent.Describe and explain the differences between the pyramids from the two countries.HINT: Think about birth rate, death rate, life expectancy and gender differences
4Mozambique, 2000Mozambique, 2025What are dependents?Describe and explain what is happening to the population of Mozambique between 2000 and 2025?

9Look at the DTM and discuss what is happening at each stage. Total population still rising rapidly. Gap between birth and death rates narrows due to availability of contraception and fewer children being needed to work. Natural increase rate is high.LEDCs, Afghanistan, Sudan and Libya.UK passed through this stage by 1850.Total population rises as death rates fall due to improvements in health care and sanitation. Birth rates remain high.Total population is high but balanced by a low birth rate and death rate. Birth control is widely available. There is a desire for smaller families.Total population is high but going into decline due to an ageing population. Still a desire for smaller families & people opting to have children later in life.Wealthier LEDCs, Brazil, China and Argentina. UK passed through this stage about 1950.UK and most MEDCs are at this stage.Germany and Sweden.No countries, some indigenous tribes. UK until about 1750.Total population is low but balanced due to high birth rates and death rates.Look at the DTM and discuss what is happening at each stage.Demographic Transition Model (DTM)
