Social Studies 11
Ms. 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.
