  1. Population Geography I The Where and Why of Population • Density • Distribution • Demographics (Characteristics) • Dynamics

  2. Cultural Hearths of Civilization

  3. 5000 BC

  4. Year 1

  5. 1500

  6. 1900

  7. World Population

  8. World Population Cartogram

  9. Population by continents

  10. Density of World Population

  11. Blackout of 2003

  12. Lower 48 states 94.7 Japan 830 NJ 1134 Lincoln Co., NV 0.4 California 217 Santa Clara Co. 1304 San Francisco. 10,632 Manhattan 66,834 Select Population Densities(people/mi2)

  13. Canada 8 Russia 22 United States 80 Holland 1002 Bangladesh 2261 Egypt 173 people/mi2 3% of area inhabited Nile River 6000 people/mi2 Population Densities(people/mi2)

  14. High density in Bangladesh

  15. Distribution:Why do we live where we live?

  16. Population Distribution in North America

  17. Trans-Siberian railroadsin eastern Russia Omsk

  18. Demography:Population characteristics • Ascribed characteristics • Achieved characteristics

  19. Characteristics • Ascribed • Gender • Race • Age • Achieved • Education • Income • Occupation • Employment • Etc.

  20. Census:Count of population and its characteristics

  21. DynamicsRate of Natural Increase (RNI) Births - Deaths = RNI

  22. National population Births - Deaths + Immigration (in) • Emigration (out) = Population growth

  23. Population increase and decrease

  24. World Birth Rate(births per 1,000 population)

  25. Doubling Time Number of years it will take for population to double, at current rate United States: 117 years Nicaragua: 21 years

  26. World Death Rate (deaths per 1,000 population)

  27. Epidemics (AIDS)

  28. Infant mortality rate(deaths of infants <1 year old) Lack of maternal health care or child nutrition

  29. Philadelphia Infant Mortality Red area high than at least 28 “Third World” countries, including: Jamaica Cuba Costa Rica Malaysia Panama Sri Lanka South Korea Taiwan Uruguay Argentina Chile

  30. Life Expectancy at Birth

  31. AGE DYNAMICS

  32. Dependency Ratio • Dependents are under 15 & over 65 • How many are supported by 15-65 group • Problems?

  33. “Graying of the Core” • Low birth and death rates in Core • Low population growth (except immigration) • Steadily older population

  34. Comparison of U.S. eras

  35. Baby Boom (1946-1964) Baby Bust (1965-1980)

  36. Baby Boom impacts yet to come • Strain on Social Security • Growing health care costs • Challenge to youth identity (Gen. X)

  37. Population Pyramidtracks age-sex groups (cohorts)

  38. U.S. (slow growth)

  39. Tanzania, Africa (rapid growth)

  40. Denmark (zero growth)

  41. Germany (effect of wars)

  42. Japan (effect of war)

  43. China (One-child policy)

  44. Canada, 1971-2006

  45. Russia, 1990-2006
