DEMOGRAPHY The study of human populations

On average during one day in Canada…
How many babies do you think are born? 1070 How many people die? 575 How many people move here? 610 How many people leave from here? 135 At the end of the day, there are 960 more people living in Canada than there were when we woke up this morning!

Demographic Terminology
A population can change naturally with births and deaths Birth Rate: Number of Births each year per 1000 People Formula: BR=(#of births per year/population) x 1000
4
Death Rate: Number of deaths each year per 1000 people
Formula: DR=(# of deaths per year /population)x1000
5
NIR= Birth Rate – Death Rate
Natural Increase Rate: Difference between the birth rate and the death rate of a country Formula: NIR= Birth Rate – Death Rate
6
Formula: (# of immigrants per year /population) x 1000
A population can also change with people immigrating to and emigrating from a country Immigration Rate: Number of new people who have immigrated to a country, per 1000 citizens of that country. Formula: (# of immigrants per year /population) x 1000
7
Emigration Rate: Number of people who leave a country per 1000 citizens of that country.
Formula: (# of emigrants per year /population) x 1000
8
Net Migration Rate: Difference between people immigrating to a country and people emigrating from the same country Formula: NMR= Immigration Rate – Emigration Rate
9
Population Growth Rate: Measurement which combines both natural increase and net migration to calculate the overall growth of a country’s population Formula: PGR = Natural Increase Rate + Net Migration Rate
10
Doubling Time How long it takes a country’s population to double
Formula: Use the Rule of 70 =70/Population Growth Rate Canada=70/1.1 =64 years to double it population
