Unit 6Population Distribution & Growth
6.1. - Population Distribution
Population Density
• Refers to the number of people in a certain area of land
Formula to calculate:
Population ÷ Land area = # of people / km2
NL for example:
(Population) ÷ (Land Area) = # ppl/km2
551,792 ÷ 405,720 km2 = 1.36
• That is there is: 1.36 people/km2
Population Density
• What is the population density of:
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
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
NL?• 1.36 people/ km2
• Sparsely populated
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 = 78.43 people/ km2
• As a country - Sparsely populated (<100 ppl/km2)• City of Barcelona, Spain = 3404 people/ km2
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?
Identify global patterns of population distribution
• Use MAP ( figure 18.5) on page 304• Make reference to density AND locations
North America
• Sparsely populated in north• Densely populated along North eastern U.S.
and south western U.S.• WHY?• Transportation? Climate? Soils/Land?
Resources??
South America
– Sparsely populated in Center– Densely populated along Western
Coast– But most dense south eastern
Brazil. – WHY?
Europe
– Sparsely populated in Extreme North– Densely populated throughout. – WHY?
Asia
– Sparsely populated in North & center– Densely populated in South East– WHY?
Africa
– Sparsely populated in Sahara– Densely in North & Sub Sahara– WHY?
Factors affecting – Population Density and Distribution
Where people live…in greater concentrations!!
I. Climate:
II. Economics:
III. Transportation:
The CLIMATE Factor – Population Density and Distribution
Climate: – Warmer comfortable climates attract people. – Notice that most people live in a moderate climate region.
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!).
The TRANSPORTATION Factor –Population Density and Distribution
Transportation:
– 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.
