2. Overview

3. Population

5. Part 1: Where is everyone?

6. The Study of Population Demos (Greek for People) + graphe (Greek for to Describe) = Demography

7. For Your Consideration: In what places on Earth do you expect to find the most people living? What common traits might these places exhibit?

8. What is population distribution?

9. “Population distributions are descriptions of locations on the Earth’s surface where individuals or groups live.”

10. What is ecumene?

11. “Ecumene is the portion of the Earth’s surface occupied by permanent human settlement.”

12. Common Traits of Global Population

13. How do you measure population?

14. “You measure population by looking at Population Density; the number of people occupying an area of land.”

16. For Your Consideration: How has the agricultural density of the United States changed over the last 200 years? Why might this be so?

17. How has ecumene changed through time?

22. What do you notice about the uninhabited areas of the earth?

23. For Your Consideration: What inferences can you make by looking at countries with a high percentage of arable land but a low agricultural density? What inferences can you make about a country with a high physiological density but a low arithmetic density?

24. Where do most people live now?

25. Two-thirds of the World’s Population is concentrated in four specific areas.

26. East Asia China, Japan, the Korean Peninsula, and Taiwan

27. South Asia India, Pakistan, Bangladesh, Sri Lanka

28. Southeast Asia The islands of Java, Sumatra, Borneo, Papua New Guinea, Philippines, Indonesia

29. Europe Largely concentrated in urban areas.

30. Part 2: Where has the World’s population increased?

31. How do you measure population change?

32. “You can measure population change through the Crude Birth Rate, the Crude Death Rate, and the Natural Increase Rate.”

33. The Crude Birth Rate (CBR) is the total number of live births a year for every 1,000 people alive in the society.

34. The Crude Death Rate (CDR) is the total number of deathsa year for every 1,000 people alive in the society.

35. The Natural Increase Rate (NIR) is the percentage by which a population grows in a year.

36. NIR = (Crude birth rate − Crude death rate) / 10

37. 2.992% = (37.89 − 7.97) / 10

39. The Total Fertility Rate(TFR) is the average number of children a woman will have during her childbearing years.

40. The Infant Mortality Rate (IMR) is the annual number of deaths of infants under 1 year compared with total live births.

41. Life Expectancy measures the average number of years a newborn can expect to live at current morbidity levels.

42. Part 3: Why is population increasing at different rates in different places?

43. For Your Consideration: What allowed the population to grow so quickly from AD 1750 – AD 2000?

44. What is the doubling rate?

45. “The doubling rate is the amount of time it takes to double a population.”

46. Timeline of Population Growth

47. For Your Consideration: What are some reasons that the doubling rate began to decrease in the 1950s?

48. What is a model?

49. “A model attempts toexplain or demonstrate why something exists the way it does. “

50. What is the demographic transition model?
