1. Population Density, Distribution & Growth

2. What if the world was one city?

3. Population Density
Refers to the number of people in a certain area of land
Formula to calculate:
Population ÷ Land area = # of people / km2
Canada for example:
(Population) ÷ (Land Area) = # ppl/km2
33,476,688 ÷ 8,965, km2 = 3.7
That is there is: people/km2

4. Population Density What is the population density of: Brazil
Bangladesh
Population 127,117,967
Land Area 133,910 km2
POPULATION DENSITY = 949 people/ km2
Brazil
Population 171,853,126
Land Area 8,456,510 km2
POPULATION DENSITY = 20 people/ km2

5. How populated? Densely populated = More than 100 people/ km2
Sparsely populated = Less than 100 people/ km2
Brazil?
20 people/ km2
Sparsely populated
Bangladesh?
949 people/ km2
Densely populated
Canada?
3.7 people/ km2

6. Population Density NOT a good indicator… why not?
Assumes people are equally/evenly spread out.
Assumes all land is usable
Assumes ALL land is USED
For example:
A country can have a low population density BUT…
Cities within that country can have a very high population density (densely populated).
Country of Spain = people/ km2
As a country - Sparsely populated (<100 ppl/km2)
City of Barcelona, Spain = 3404 people/ km2

7. Population Distribution
Describes how people are spread out.
Where people live!
When combined with population density gives a more accurate picture of the population.
Where are the heavier concentrations of people versus the sparsely populated areas?

8. So where do people live?

9. Identify global patterns of population distribution
What do you notice about Global Population Distribution?

10. North America Sparsely populated in north
Densely populated along North eastern U.S. and south western U.S.
WHY?
Transportation? Climate? Soils/Land? Resources??

11. South America Sparsely populated in Center
Densely populated along Western Coast
But most dense south eastern Brazil.

12. Europe Sparsely populated in Extreme North
Densely populated throughout.

13. Asia Sparsely populated in North & center
Densely populated in South East

14. Africa
Sparsely populated in Sahara
Densely in North & Sub Sahara

15. Why do people live places?
People choose their locations based on two sets of factors:
Physical Factors
Human Factors

16. Physical Factors Climate Landscape Resources Soils Vegetation Water
Accessibility

17. Human Factors Government Policies Disease Development Culture
Communication

18. Another way to look at Population Density and Distribution
Where people live…in greater concentrations!!
Climate:
Economics:
Transportation:

19. The CLIMATE Factor – Population Density and Distribution
Warmer comfortable climates attract people.
Notice that most people live in a moderate climate region.

20. The ECONOMIC Factor – Population Density and Distribution
Economics:
Used to be around resources and good land!!
BUT No longer ! Why not? (Hint: what sector is now most important in Canada?)
Industrialization & manufacturing has caused Urbanization
and now the information age causing the development of suburbs (away from urban!).

21. The TRANSPORTATION Factor – Population Density and Distribution
Coastal regions attracted business and people because of ocean transportation.
It was true for initial settlement and is still true today!
TODAY! Most major cities are located on the coast.
