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)

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, Canadas population was
  reduced by fewer births and losses of soldiers.

8
MIGRATION

• Immigration adds people to a countrys
  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)

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.
