  1. REVIEW • What is Urban Sprawl? • Dallas would be an example of which Urban Sphere? • What are some good things about Urban Sprawl? • In which Sphere would we find Suburbs? • What are some bad things about Urban Sprawl?

  2. What might have occurred in this country?

  3. UK

  4. Mexico

  5. China

  6. Based on the population pyramid, which statement is the most accurate?1. The rate of natural increase in the population is slowly increasing but still low.2. The rate of natural increase in the population is rapidly increasing but is low.3. The rate of natural increase in the population is rapidly declining but remains high.4. The rate of natural increase in the population is slowly declining but remains high.

  7. Nazi Germany tried to kill every male in Serbia between the ages of 16-60. Which population pyramid from the year 2005 below most likely belongs to Serbia? Females Males 2. 1. 3. 4. Females Males

  8. Earliest Migrations • First migration began in Africa • What seem to be the biggest obstacle to early migration? • Hint not many ships back them

  9. Christianity, Judaism, and Islam all originated in the Middle East • Hinduism and Buddhism originated in India

  10. DEMOGRAPHIC TRANSITION MODEL Which stage will have the largest population increase?

  11. Demographic Transition Model

  12. 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.

  13. 10 minutes Task One • Make a copy of the DTM in your notes, across the page (landscape). • Make sure you add appropriate labels/detail.

  14. Stage One Birth Rate and Death rate are both high. Population growth is slow and fluctuating. Birth Rate is high because of: • Lack of family planning • High Infant Mortality Rate: putting babies in the 'bank' • Need for workers in agriculture • Religious beliefs • Children as economic assets Death Rate is high because of: • High levels of disease • Famine • Lack of clean water and sanitation • Lack of health care • War • Competition for food from predators such as rats • Lack of education Typical of Britain in the 18th century and the Least Economically Developed Countries (LEDC's) today.

  15. Stage Two Birth Rate remains high. Death Rate is falling. Population begins to rise steadily. Death Rate is falling as a result of: • Improved health care (e.g. Smallpox Vaccine) • Improved Hygiene (Water for drinking boiled) • Improved sanitation • Improved food production and storage • Improved transport for food • Decreased Infant Mortality Rates Typical of Britain in 19th century; Bangladesh; Nigeria

  16. Stage Three Birth Rate starts to fall. Death Rate continues to fall. Population rising. Reasons behind birth and death rate falling: • Family planning available • Lower Infant Mortality Rate • Increased mechanization reduces need for workers • Increased standard of living • Changing status of women Typical of Britain in late 19th and early 20th century; China; Brazil

  17. Stage Four • Birth Rate is low. • Death Rate is low. • Population steady. Typical of USA; Sweden; Japan; Britain

  18. Typical of Germany Stage Five • Birth Rate slight fall. • Death Rate stable. • Natural increase: gentle decrease Reasons for changes in birth rate: • Family planning • Better health • Later marriages • Improved status of women Reasons for changes in death rate: • Good health care • Reliable food supply • People are generally living longer

  19. JAPAN 2050 STAGE 5 • Death Rates drop as low as is possible • Birth Rates continue to drop • Total Population begins to decrease • Japan and Germany are two example of stage 5 countries

  20. What are the limitations? What limitations do you think there could be with the model? • It does not include the influences of migration • It assumes that all countries will go through the same pattern • There is no time scale • Reasons for birth rates and death rates are very different in different countries

  21. To finish… http://www.youtube.com/watch?v=pzxREH08EkI ‘DTM’ You are about to watch a clip on the DTM. It will summarise what we have learned today.
