1 Population (continued) Ms. Shrieves

2 Population Pyramid Review 1. Why does the pyramid narrow toward the top? The death rate is higher among older people than among younger people. 2. Why are there a few bulges and narrower parts in the middle of the pyramid? People in their 20s in 1961 were born during the depression, a time of economic hardship in Canada when people were having fewer children. 3. Why does the pyramid have a wide base? 35% of the population was under 15 – these are the “baby boomers” a large group of people born between 1947 and 1966 when the economy was growing and prospering.

3 Population Pyramid Review http://www12.statcan.ca/english/census01 /products/analytic/companion/age/cda01p ymd.cfm http://www12.statcan.ca/english/census01 /products/analytic/companion/age/cda01p ymd.cfm

4 Canada’s Population: Past and Future Canada’s birth and death rates have been dropping steadily in the past years. ◦ As a result, what is happening? Population is getting older. - In 1951, one in 10 Canadians was over 65 - In 2020, one in 5 will be over 65

5 Aging Population Increasing number of elderly people put a big strain on social and medical services Fewer children to look after aging parents Pressure on health care system to provide more long-term care for elderly Cost of health services for the aged continues to rise as medical technology becomes more complex

6 Dependency Ratio The portion of the population that is being supported by the working population (People under 16 and older than 65 being supported by cohorts b/w 16 and 65 years) Why is it important for a country to know what their dependency ratio is? Children and older people put pressure on medical services, education, housing and other services.

7 Question: Why does an aging population present a serious problem in the developed world? Having an increasing number of elderly people in a population puts a great strain on social and medical services. There are fewer children to look after aging parents. The need for expensive long-term care and new medical technology is growing.

8 Population Distribution The way people are spread over the Earth’s Surface

9 Fun Facts 35% of the world’s land area is not good for settlement Over half the population lives on only 5% of the worlds land 90% of people live on 20% of the land 2/3 of people live within 500km of the ocean

10 Population Density: The number of people in a given area. Physical Factors: - Climate - Landscape - Resources - Soils - Vegetation - Water - Accessibility Human Factors: - Communications - Culture - Development - Disease - Government Policies

11 Canada: 3 people per square KM

12 Pakistan: 202 people per square KM

13 Monaco: 16,000 people per square KM

14  Climate  Resources  Accessibility

15  Development  Government Policies

16 1. Improve technology: Countries with higher levels of technology tend to have more developed economies. 2. Family planning: Reduced population reduces strain on resources, increase in standard of living.

17 3. Increase resource base: Use own resources to develop itself 4. Improve Literacy rate: Improves access to higher paying jobs. 5. Opportunities for women: Leads to economic development.
