  1. Answers Population Problem Set

  2. Historical Population • What was the world’s population in 1804? • 1 billion • Examine the world’s population in 1927, 1960, 1974, 1987, 1999 ~ what trend do you notice? Exponential (fast) population growth • Examine the world’s population in 2013, 2028, 2054, 2200 ~ what trend do you notice about projections? Rate of Population Growth is decreasing - (natural increase)

  3. Historical Population Growth

  4. United Nations Population Models

  5. Measuring Population Change • Population change is measured by four basic components: • How many people are born – BIRTH RATE • How many people die – DEATH RATE • How many move into an area – IMMIGRATION RATE • How many move out of a region (EXIT) – EMIGRATION RATE

  6. NATURAL INCREASE • NI = BIRTH RATE – DEATH RATE • Canada’s Natural Increase: 10.6 – 7.4 = 3.2 per 1000 (STABLE/CONTRACTING) • Russia’s Natural Increase: 10.8 – 15.1 = -4.3 (CONTRACTING) • India’s Natural Increase: 23.0 - 8.5 = 14.5 (EXPANDING)

  7. CENSUS DATA • Every 5-10 years in Canada • Questions for Canada’s population – gives government information to help provide services • Very important Accuracy based on infrastructure, literacy rates, political stability, government freedom, wealth of a country

  8. World Population Density* Crowdedness *

  9. Canada’s Population Density

  10. World’s Largest Cities 1. Tokyo – 37 m 2. Jakarta – 26m 3. Seoul – 22m 4. Dehli 5. Shanghai – 20m 10. Mexico – 19m

  11. POPULATION FACTS The world’s population growth pattern has been exponential; it is increasing at a rapid pace that can seem uncontrollable at times. Why the explosion in population growth? • The number of people (death rate) is decreasing due to better medical care • Birth rates continue to be high in COUNTRIES THAT STRUGGLE WITH POVERTY however in many newly industrializing countries like India, infant mortality is decreasing. But Surprise! The world’s population growth rate is decreasing on every continent. We reached our peak growth rate around 1950, and our rate of natural increase is decreasing globally.

  12. BRAINSTORM Why would people want a large family?

  13. BABY-O-MATIC • Guaranteed 100% accuracy • Discuss your score with your group • Discuss how many children you actually believe you will have • Using your ‘Sherlock’ Inferencing Skills – determine what factors will affect the number of children a woman may have in her lifetime.

  14. Why Do Some Countries Have Large Populations and Other Small? • Career Prospects • Birth rates • Death Rates • Health Care • ‘Need for Children’ – poverty • Education levels • Women’s Rights • Infant Mortality Rate • Rural living – more workers needed to collect water, etc. • Sons bring wealth, dowries, etc. • Sense of community AGE THAT WOMEN HAVE THEIR FIRST CHILD IS EXTREMELY SIGNIFICANT - LONGER PROLONGED, LOWER POPULATION RATES

  15. AGE PYRAMID - CANADA

  16. CANADIAN STATS • Overall Population Density is extremely low • Average Life Expectancy is 81 years old • BC – Men 80, Women 84 • Rate of Natural Increase is 4.0 (2013) • Population growth rate is highest of all G8 countries – 2/3 of growth rate is from immigration – important to support aging population of BABY BOOMERS

  17. Pyramids Tell a Story

  18. Germany’s Age Pyramid

  19. What Does Your Pyramid Look Like? • Explain your pyramid to your partner! What is the story behind your population? • What are your country’s “prospects for the future”? • Ensure is complete ~ worth 5 marks
