1. The study of human populations
DEMOGRAPHY
The study of human populations
Found out through a census! Show academics the powerpoint!
And the statistics website of Canada

2. 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!

3. Canada’s Current Population:
Births per year: 385,937
Deaths per year: 256,721

4. Lets say a country has a population of 30,000,000
Births per year= 390,000
Deaths per year= 210,000
# of Immigrants= 220,000
# of Emigrants= 60,000

5. 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
What happens when the birth rate is higher than the death rate?

6. Death Rate: Number of deaths each year per 1000 people
Formula:
DR=(# of deaths per year/population)x1000

7. 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

8. 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

9. Emigration Rate: Number of people who leave a country per 1000 citizens of that country.
Formula: (# of emigrants per year /population) x 1000

10. Net Migration Rate: Difference between people immigrating to a country and people emigrating from the same country
Formula: NMR= Immigration Rate – Emigration Rate

11. 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/1000 * 100

12. Doubling Time: How long it takes a country’s population to double
Formula: Use the Rule of 70
Doubling Time=70/Population Growth Rate
