Unit 6. Population Distribution & Growth. Population Density. Refers to the number of people in a certain area of land A ratio can be calculated by: Population ÷ land area = number of people per unit of land Using NL for example: 551,792 (Population) ÷ 405,720 km 2 (Land Area) = 1.36

  1. Unit 6 Population Distribution & Growth

  2. Population Density • Refers to the number of people in a certain area of land • A ratio can be calculated by: Population ÷ land area = number of people per unit of land Using NL for example: • 551,792 (Population) ÷ 405,720 km2 (Land Area) = 1.36 • There is 1.36 people/km2

  3. 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 Population Density

  4. Densely populated = More than 100 people/ km2 Sparselypopulated = Less than 100 people/ km2 Bangladesh? 949 people/ km2 Densely populated Brazil? 20 people/ km2 Sparsely populated NL? 1.36 people/ km2 Sparsely populated How populated?

  5. Population Density NOT a good indicator of Population Distribution Why not? • Assumes people are equally/evenly spread out. • For example: • A country can have a low population density, but • Cities within that country can have a very high population density. • Country of Spain = 78.43 people/ km2 • City of Barcelona, Spain = 3404 people/ km2

  6. 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.

  7. Identify global patterns of population distribution • Use MAP ( figure 18.5) on page 304 • Make reference to density AND locations

  8. North America • Sparsely populated in north • Densely populated along North eastern U.S. and south western U.S. • WHY?

  9. South America • Sparsely populated in Center • Densely populated along Western Coast • But most dense south eastern Brazil. • WHY?

  10. Europe • Sparsely populated in Extreme North • Densely populated throughout. • WHY?

  11. Asia • Sparsely populated in North & center • Densely populated in South East • WHY?

  12. Africa • Sparsely populated in Sahara • Densely in North & Sub Sahara • WHY?

  13. Factors affecting Population Density and Distribution • Climate: • Warmer comfortable climates attract people. • Most people live in a moderate climate region. • Economics: • Population distribution has changed over time. • No longer are dense populations around primary resources. • Urbanization and the move to the industrial and now the information ages have changed population distribution. • Transportation: • Coastal regions attracted business and people because of ocean transportation. • It was true for initial settlement and is still true today. • Most major cities are located on the coast.
