Population Distribution
Refers to the pattern of settlement • The way the population is spread
Population Density:
Formula =
Population / Land Area
Refers to the number of people living in a given area (ex: 1km2)
Demography
Demography is the study of population numbers, distribution of people, trends of people, and issues relating to population. Demos = People Graphos = write about
Demographer:
a profession whose responsibility is to analyze qualitative and quantitative data to understand trends and patterns for private or public use.
Birth rate
– Yearly number of live births per 10
Death rate
yearly number of deaths per 1000
Natural increase rate
the difference between birth and death rate. (Birth rate – Death Rate)
Infant Mortality Rate
: yearly number of deaths under 1 year old per 1000
Child mortality rate:
yearly number of deaths under 8 years old
Immigrate
– to move out of your old country
Immigration rate
– number of new Canadians who have immigrated here from another country

Population Growth Rate –

Life expectancy –
average lifespan of a person in a country
Baby Boom
– the largest rise in the birth rate in the late 1940’s and 1950’s experienced by
many countries in Europe and North Ameri
Doubling time
how long it would take for a country’s population to double at that country’s rate of population growth
70 / population Growth Rate = Doubling Time
There are THREE types of Population Pyramids
? Stable Pyramid
? Expanding Pyramid
? Contracting Pyramid
Reasons for our older population:
o Health Care, Birth control & family planning have made families have fewer but higher achieving children, as well as allowing Canadians to live longer lives
o Children are very expensive and families want to balance a high standard of living with raising a family. Student debt and high cost of housing is also pushing back family formation.

How does this affect us? (Older population)
o With low birth rates and longer life spans our problems will worsen in the future
o Our social safety system could become unsustainab
