1. Demography

2. What is Demography? The study of human population Birth rate
Death rate
Immigration
Emigration
Population growth rate
Natural increase
Dependency load
migration

3. On an average day in Canada there are….
1050 births per day 690 deaths per day 769 immigrants per day 135 emigrants per day

4. So that means…..
…. on an average day there will be 836 more people in Canada at the end of the day than there was at the beginning of it

5. Birth Rate

6. Birth Rate Number of births in a country per 1000 people.
Calculated by dividing the number of births in one year by the population and then multiplying the result by 1000.
BR = (# of births/population)*1000

7. Example
Births = 390,000
Population = 30,000,000
BR = (390,000/30,000,000)*1000
= 13 births per 1000 people

8. Death Rate

9. Death Rate Number of deaths in a country per 1000 people.
Calculated by dividing the number of deaths in one year by the population and then multiplying the result by 1000.
Death Rate = (# of deaths/population)*1000

10. Example
Deaths = 120,000
Population = 30,000,000
DR = (120,000/30,000,000)*1000
= 4 deaths per 1000 people

11. Natural Increase Rate

12. Natural Increase Rate = (BR – DR)*100 (expressed as a percent)
Calculated using the birth and death rate. It is the most important reason why a country’s population changes, either increases or decreases.
Natural Increase Rate = (BR – DR)*100 (expressed as a percent)

13. Natural Increase Rate = (13/1000-4/1000)*100 = 0.9%
Example
BR = 13 per 1000 people
DR = 4 per 1000 people
Natural Increase Rate = (13/1000-4/1000)*100
= 0.9%

15. Migration

16. the movement of people from one place to another
Migration
the movement of people from one place to another

17. Immigration- occurs when people arrive in a new place.
Types of Migration
Immigration- occurs when people arrive in a new place.
Emigration-occurs when people leave a place.

18. Net Migration
difference of immigrants and emigrants of an area in a period of time, divided per 1,000 inhabitants

20. Population Growth Rate

21. Population Growth Rate
amount that the population of a place is either increasing or decreasing over time.

22. Population Growth Rate
So for a country’s total growth rate we look at both Natural Increase and Net Migration.
Growth Rate=
(Natural Increase Rate + Net Migration Rate)

23. Example
Natural Increase Rate = 0.9% Net Migration Rate = 0.5% Growth Rate = 0.9% + 0.5% = 1.4%

24. Whether a country’s population is growing or declining has an enormous influence on the lives of the people.
If a country’s population is growing you must consider issues with providing enough housing, education, healthcare, employment, etc.
If a country’s population is declining there may be a shortage of workers and consumers to meet the needs of the country’s businesses.

25. Doubling Time

26. Doubling Time
This tells us how long it will take for a country's current population to double. It is determined by dividing 70 by a country’s Growth Rate.

27. Population Growth Rate: 1.4% Doubling Time = 70 / 1.4 = 50 years
Example
Population Growth Rate: 1.4% Doubling Time = 70 / 1.4 = 50 years

28. Other things to look at

29. Total Fertility Rate
Is the average number of children a woman is likely to have during her childbearing years. For a population to replace itself at a stable level this rate is 2.1

30. Dependency Ratio
The dependency ratio tells you how many economically inactive people (0-15 and 65+) are dependent upon the economically active population (16 to 64).
The equation above calculates a figure that shows the number of economically inactive people that are reliant on 100 economically active people.

31. Example
A result such as 81.8 would mean that for every 100 economically active people there are 81.8 economically inactive people.
