  1. 3rd Key Question: Why does Population Composition Matter?

  2. Population Composition Population Composition is concerned with: • Gender distribution • Age distribution within a country, region, or place.

  3. Population Pyramids/ Structures

  4. Population Structures • Rapid Growth (Baby Maker!) • Most of developing world. • Populations increase so fast that doubling time can = 25 years. • High percent of population is under 19 (60%). • Resource usage is high, but a low standard of living exists. Any increase on S.O.L is absorbed by population growth. • Slow Growth (The Chimney) • Developed countries (U.S, Canada, some W. Europe) • Long doubling time, • Resources are used to maintain infrastructure. • Under 19= 25=30% Some have no growth and stable populations. • Negative Growth (Zombie Apocalypse) • Very few countries: Japan, Italy, Austria. • Under 19= less than 25% • averaging less than 2 children per family. • Resources- to increase standard of living.

  7. Age Structure of a Population • The populations of many countries are aging. - eg. Europe - eg. Japan Bordeaux, France Photo credit: H.J. de Blij

  8. Aging Populations • To replace the population, TFR must be 2.1. - TFR in Bologna, Italy is 0.8 - Why are women having fewer children? • What are the impacts of an aging population on a country? • What are the “solutions” to an aging population?

  9. 4th Key Question: How do Governments Affect Population Change?

  10. Government Population Policies • Expansive Population Policies (Pro-Natal) - Encourages population growth. • Eugenic Population Policies - Favors one racial or cultural sector over others. • Restrictive Population Policies (Anti-Natal) - range from toleration of unapproved birth control to outright prohibition of large families.

  11. China’s One Child Policy What are some of the limitations, unintended consequences, and contradictions found in government policies toward population growth?
