  1. Population

  2. Where would you rather live?

  3. Population • There are more than 7 billion people living on the earth. • This number has grown drastically since the 1600’s. • BBC Link

  4. Population Growth Chart Why such a drastic increase?

  5. Why Population Growth • 1600 – 1800 - The Columbian exchange between Europe and North America. • Brought nutrient rich foods to Europeans • Gave open land for population to expand

  6. Why Population Growth? • Industrial Revolution • Lead to advances in the technologies of food production, transportation, communication, electricity and medicine.

  7. Population • Almost 2/3 of the earth is covered by water • ½ the land is unusable • As people adapt to the environment they change the environment • Cutting down trees, building houses, cities, etc.

  8. Why should we care? • Rapid growth poses many problems for our world • Famine • Disease • Natural resource depletion • It will impact what services will be available to you.

  9. Population rates • The population is growing at different rates around the world • Birth rate higher than death rate = increased growth • Death rate higher than birth rate = decrease growth • The growth rate overall has slowed

  10. Where do most people live?

  11. Population Patterns

  12. Patterns of Settlement • Population is unevenly distributed around the world • Most people live in Asia, Europe, and Eastern North America • Growth is higher in Urban areas or in less developed nations. Why?

  13. Are we dense? • Population density = • Average number of people/sq. mile

  14. Comparing Population Growth • Demography – The study of populations that uses statistics to compare and predict. • Past – Present - Future • A common tool used to compare is the population pyramid.

  15. Population Pyramids • Used to illustrate information about the age and gender of a population in a given area. Cohorts – The genders at each age range. Age Percentage of the Population

  16. Population Pyramids • Three Types • Expansive • Constrictive • Stationary

  17. Population Pyramids Males Females Age 90+ 85 80 75 70 65 60 55 50 45 40 35 30 25 20 15 10 5 0 - 4 8 6 4 2 0 2 4 6 8 Percent of Population

Cite evidence. • Why do some believe this number is greater? • How will this impact the future of the Middle East?
