The document describes the four stages of the demographic transition model: Stage 1 - Both birth and death rates are high due to diseases, famine, lack of infrastructure. Stage 2 - The death rate begins to fall due to improvements in sanitation and medicine. The birth rate remains high due to social and economic factors. Population growth is rapid. Stage 3 - The birth rate starts to fall due to increased access to family planning, fewer child deaths, urbanization, and social/economic changes. Population growth slows. Stage 4 - Both birth and death rates are low, resulting in low population growth or steady population levels, as seen in developed nations today.

1. Demographic transition model

2. Sweden

4. 2. Famine and Malnutrition.

5. 3. Lack of clean water and sewerage facilities(alcantarillado).

6. 4. Lack of medical care and drugs

8. Reasons for a high birth rate are:

9. 1. Economic - many children mean more workers in the field.

10. 2. Social - No birth control or family planning. Families hope that more children will survive childhood and support the parents in old age. Children are a sign of virility in some cultures.

11. 3. Political - Muslim and Catholic Governments encourage large families and do not provide much education about family planning.

12. During stage 2 the birth rate remains high but the death rate starts to fall to about 20 per 1000 people. By the end of this stage, both rates are very different. This gives a high natural increase and a rapid growth in population live.

13. Declining world mortality

15. 1. Family planning and birth control.

16. 2. Fewer children die (lower infant mortality)thanks to better medical care and they don`t need large families.

17. 3. People in cities can`t support(mantener) many children while people in farms require less work .

18. 4. The materialistic society more interested in having a TV or a fridge than a large family

19. 5. Developed countries create state pensions,for elder people not to depend on their children.

20. 6. More women stay in higher education, pursuing careers before a marriage.

21. Total fertility rate
