17. High density in Bangladesh

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

19. Population Distribution in North America

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

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

23. Census:Count of population and its characteristics

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

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

26. Population increase and decrease

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

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

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

30. Epidemics (AIDS)

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

33. Life Expectancy at Birth

34. AGE DYNAMICS

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

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

37. Comparison of U.S. eras

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

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