1. FACTORS AFFECTING POPULATION GROWTH CGC1D ~ Canadian Geography

2. Brainstorm: Population Growth What factors might cause a population to grow? What factors might cause a population to decline?

3. Brainstorm: Population Growth Is this something we should be concerned about? How will a growing population impact the world? (e.g. resources)

4. Introduction Clip The world’s population hit 7 billion October 31, 2011! 7 Billion, National Geographic Magazine (youtube.com) http://www.youtube.com/watch?v=dx895LMG9zs

5. POOR ECONOMIC TIMES In developed nations, when there are times of high unemployment and scarcity of money, people tend to have few children due to increased costs; eg. During the Great Depression, there was massive unemployment and poverty resulting in people having fewer children.

6. GOOD ECONOMIC TIMES In certain circumstances, new found prosperity can encourage couples to have children; e.g. in the years that followed WWII (1946-1964) many couples found that they could afford more children with higher salaries and government benefits, resulting in a “baby boom”.

7. WAR War reduces the population by limiting the number of births that can occur because males (and increasingly females) are away at war. War kills many soldiers and/or civilians. In both WWI and WWII, Canada’s population was reduced by fewer births and losses of soldiers.

8. MIGRATION Immigration adds people to a country’s population. Emigration results in a loss of population. Depending on the country you live in, you may be a receiver / loser of population through migration. (More information to follow in the next chapter)

9. LITERACY / WEALTH / EDUCATION / HEALTHCARE Literate people are better able to understand birth control in order to make it effective. Literate people are more likely to go to college or university, delaying marriage.

10. LITERACY / WEALTH / EDUCATION / HEALTHCARE Literate people are more likely to make more money and can afford better health care – more babies are likely to survive and therefore couples are likely to have fewer children in addition to increasing lifespan and eliminating many diseases.

11. EPIDEMICS / PANDEMICS Widespread occurrences of diseases in a community (Epidemics) or around the world (pandemics) that kill thousands or millions of people; eg AIDS is a serious pandemic that kills millions worldwide each year.
