  1. Population notes

  2. World Population Milestones • 1 billion in 1804 • 2 billion in 1927    (123 years later) • 3 billion in 1960    ( 33 years later) • 4 billion in 1974    ( 14 years later) • 5 billion in 1987    ( 13 years later) • 6 billion in 1999    ( 12 years later)

  5. Population Patterns 1. Population distribution – An area’s physical environment, especially climate, limits the number of people who can live there. There are 4 centers of heavy population in the world:

  6. A. Eastern Asia

  7. Eastern Asia has the greatest concentration of people on earth – it is centered in China – 21% of the Earth’s population

  8. B. South Asia

  9. South Asia is the second largest concentration of people—it is centered in India – 16% of the world’s population.

  10. C. Western Europe

  11. Europe is the third largest concentration. Western Europe- people are concentrated near natural resources needed for industry.

  12. D. Eastern U.S.

  13. D. East US. In the US, the chain of cities start from the city of Boston to south of Washington D.C. This is called a megalopolis.

  14. Population Density – tells you how concentrated the numbers of people are in an area. It makes it possible to compare areas of different size and population in an area.

  15.

  16. Population Issues

  17. 1.   1.  Food Supply a.      13-18 million people die each year because they do not have a good diet (35,000 a day, 24 a minute)

  18. B. The population explosion has raised such issues as how to increase food supplies. Drying rice in Thailand

  19. C. How to make better use of farmland.

  20.   D.   How to find new sources of food.      1.Today 90% of the world’s food comes from 15 crops and 7 livestock animals      2. There are more than 10 million kinds of plants and animals on Earth.

  21. E. Natural Resource Issues 1.  Certain resources are in limited supply, such as fossil fuels 2. Fresh water is one basic resource that is being threatened.

  22. Migration • 1. People move because of either economic or political reasons (push- pull forces) • 2.   Worldwide, more people are moving from the countryside to urban areas – and from developing to industrialized countries. This places huge demands on the country or cities economy.

  23.  Economic Geography AA. Various levels of economic activities. 1. Primary economic activities make direct use of natural resources. a. Agriculture b. Forestry c. Mining

  24. 2.     Secondary economic activities convert raw materials into new products. a.      Food processing b.     Manufacturing c.     Refining

  25. 3. Tertiary economic activities refer to service industries
