1. IGCSE Population Review and Revision 40 slides, 20 minutes; sit back and enjoy….. Moses Lutta

4. Population Change The Population Formula Natural Population Change = Birth Rate (BR) – Death Rate (DR) Moses Lutta

6. Moses Lutta

8. Mozambique – An LEDC Moses Lutta

9. The UK – An MEDC Moses Lutta

10. Moses Lutta

11. Population Explosion Moses Lutta

12. Individual Decisions This explosion occurred largely in LEDCs and results from millions of individual decisions that are influenced by the characteristics of the places people live. Moses Lutta

13. LEDC Population Trends and Issues High birth rates and falling death rates leading to rapid population growth – the population explosion Youthful populations Moses Lutta

16. Youthful Populations Death rate maybe be falling in LEDCs but life expectancy is still low – the result when combined with high BR is a youthful population Moses Lutta

18. Youthful Population Pyramid Moses Lutta

19. Overpopulation Issues Moses Lutta

20. Overgrazing and Overcultivation As seen in the Sahel region of Africa including Darfur in western Sudan Moses Lutta

21. Deforestation and Soil erosion Again think Mato Grosso, Amazonia (Brazil) the Sahel (Darfur) Moses Lutta

22. Overcrowding and the growth of Shanty Towns Favelas in Brazil (Rio de Janeiro) Busties in India, e.g. Mumbai Slums in Jakarta Moses Lutta

24. Traffic Congestion And Rio once again – think of the road to Barra Moses Lutta

25. Crime and Lawlessness Moses Lutta

27. Youthful Populations Many young people (with a high youthful dependency ratio) puts pressure on schools, taxes, families; and exacerbates problems associated with rapid population growth and over population in LEDCS – this can hinder development Moses Lutta

30. MEDC Population Trends and Issues Ageing population in MEDCs result from long life expectancies , low fertility rates and the legacy of the post-war baby boom Moses Lutta

33. Post-war Baby Boom Moses Lutta

34. Example case studies where the issues of an ageing population are happening now. Italy, UK, Germany, (western Europe), Japan, South Korea Maybe even China??? Moses Lutta

35. Ageing Population Pyramid Moses Lutta

36. Moses Lutta

39. Completing the formula - Migration Population change within an area needs to consider both natural change (BR-DR) and migration (add those who move in and subtract those who move out) Moses Lutta
