CH. 13 – POPULATION: CANADA AND THE WORLD

Social Studies 11Ms. Shrieves

INTRODUCTION 1999 – The world had 6 Billion People (UN)

2020: Estimated 7 Billion What are the consequences of a rise in

population?

Question being asked by these people?

Other side of the argument:

- Shortages in energy, housing and food, an increase in pollution, unemployment and the destruction of

the environment.

At what point will the world’s resources fail to support it’s population

Technology will find ways to provide for increased # of people

WHAT DO YOU THINK?

WORLD POPULATION GROWTH

Hans Rosling on Global Population Growth Video

Why would there have been a rapid growth in population in the twentieth century?

DEMOGRAPHY Demography: The statistical study of

human populations

Why is demography important?

Helps to understand the causes and consequences of population change

Gives local, provincial and federal governments accurate statistics of population shifts

Business like information about family size, incomes and consumer habits as they plan their marketing strategies

CENSUS

Census:. Canada conducts a detailed census

The formal counting of people every ten

years

LIMITATIONS OF THE CENSUS

Difficult to keep track of people with no fixed address.

People may fear the authorities so not put down truthful information.

Illiteracy and poor communication networks undermine a nations ability to maintain accurate records.

In developing countries – data is much less accurate due to incomplete registration of births and deaths.

DEVELOPED COUNTRIES

Have highly developed economy Citizens have the highest standard of living in

the world High levels of literacy, health services, and

food supplies

DEVELOPED

DEVELOPING COUNTRIES An economy that depends more on primary

industries. Citizens have lower standard of living than

those in developed countries Usually highly indebted.

DEVELOPING

LEAST DEVELOPED COUNTRIES Given to those who have exhibited the lowest

levels of socio-economic development Very much indebted to developed countries. Political unrest.

LEAST DEVELOPED

POPULATION RATES

Three components of population change 1. How many people are born 2. How many people die, and 3. How many people move in or out of an area

(immigration or emigration)

POPULATION RATES

Crude Birth Rate = Number of births in one year

Population X 1000

Crude Death Rate = Number of deaths in one year

Population X 1000

Rate of Natural increase = Deaths – Births

THE RULE OF SEVENTY

-Exponential rate of increase: a rapid rate of increase as each generation doubles in size.

- “Rule of Seventy” states that doubling time is approximately equal to 70 divided by the growth rate (%) per year.

- Doubling Time: The number of years it takes a country to double its population at its current birth rate.

THE EFFECT OF MIGRATIONS

Population increase in some countries (esp. Canada) depends on immigrants Emigrants leave every year as well, which will

affect the demography.

Immigration Rates: Rates at which people immigrate to a country usually based at the number of people per thousand who enter a country.

Emigration Rates: The rate at which people emigrate, usually based on the number of people per thousand who leave a country

Net Migration rate: Difference between immigration and emigration rates.

WHY DO PEOPLE MIGRATE TO CANADA? Most immigrants to Canada come as

economic migrants from developing nations, wanting to better their standard of living.

Others come as refugees seeking to escape persecution in their home country.
