  1. Chapter 2: Population The Cultural Landscape: An Introduction to Human Geography

  2. Why Is Population Increasing at Different Rates? • Demographic transition • Four stages • Stage 1: Low growth • Agricultural revolution • Stage 2: High growth • Industrial Revolution • Stage 3: Moderate growth • Stage 4: Low growth • Zero population growth (ZPG)

  3. Demographic Transition Figure 2-15

  4. Why Is Population Increasing at Different Rates? • Population pyramids • A bar graph showing a place’s age and sex composition • Shape of the pyramid is determined mainly by the CBR • Age distribution • Dependency ratio • Sex distribution • Sex ratio

  5. Population Pyramids Figure 2-19

  6. Why Is Population Increasing at Different Rates? • Countries are in different stages of the demographic transition • Three examples: • Cape Verde = High growth • Stage 2 since the 1950s • Chile = Moderate growth • Stage 3 since the 1960s • Denmark = Low growth • Stage 4 since the 1970s

  7. Why Is Population Increasing at Different Rates? Up next: Migration • Demographic transition & world population growth • Most countries = stage 2 or stage 3 of the Demographic Transition • Stages 2 and 3 are characterized by significant population growth • No country is in stage 1 of the demographic transition • It is easier to cause a drop in the CDR than in the CBR
