DEMOGRAPHY

Where do People Live?

Why?

• Our settlement patterns are dependent on climate, access to resources, topography, and history.

• Population Density is a measure of how many people are living per square KM. It varies quite a bit worldwide.

• Mostly in mid-latitudes, often on waterways, not in deserts or mountain ranges.

• Demography – The study of the characteristics of human populations, such as size, growth, and distribution.

Population Growth Facts

• World Population reached 1 billion in 1810.

• We’ve added 6 billion in 200 years.

• Current population is 7.4 billion – this number is double the population in 1965.

• It is estimated that we will reach 9 billion by 2045

• Population growth rates are now declining – but we are living longer!

Does the Earth have a Carrying Capacity?

• Estimates say that 9 billion can be provided for in today’s world with current technology.

• However – consumption of the world’s resources is very unequal.

• North Americans consume 3.3 times the subsistence level of food and 250 times the subsistence level of clean water.

• If everyone lived like this the world could support a population of only 2 billion!!!!

• The richest 20% of the world consume 86%

• the poorest 20% of the world consume 1.3%

How many “Earths” would it take to sustain the world if everyone lived like?:

Inequality in the World

• Developed World – countries with stable governments, significant infrastructure, access to clean water, food, and shelter. Access to health care and education and other basic human rights. Countries with large economies.

• All of North America and Europe, some of South America and Africa, more and more in Asia.

• The opposite is the Developing World

• Most of the world’s population growth is in this part of the world.

HDI – Human Development Index

• Established by the United Nations to measure quality of life and development.

• 2015 Rankings:

1. Norway 0.944

2. Australia 0.935

3. Switzerland 0.930

8. USA 0.915

9. Canada 0.913

187. Niger 0.337

Canadian Demography

• Canada is much like many countries in the developed world:

• Declining birth rates and TFRs

• Increasing life expectancy

• Increasing median age

• *** The population is getting older and RNI is going to become negative in a few decades.

• Canada’s population continues to grow because of net migration levels

Why are birth rates and TFR declining?

• Children are now an economic burden instead of potential income generators or farm help

• The state now covers care for seniors

• Social priorities

– Role of women has changed

– Access to contraception

– Having children no longer a top priority – no longer a “duty”.

Generations

• Baby Boomers – people born between 1945-1965. Represent a huge portion of our population (now at retirement)

• Generation X – Born after the baby boom –not as numerous

• Generation Y (Echo Boomers) – the children of baby boomers – (now entering workforce). Represent a small population boost
