Population Distribution and Density
Transcript of Population Distribution and Density
Population Density and Distribution
Refers to where people live around the world. For example, in the United States most people live on the coasts or near major waterways. Population is not evenly distributed around the world.
There are several factors that effect distribution patterns:
People live closer to valuable resources such as oil, arable land and fresh water.
There are parts of the world people cannot live in.
People don't live in areas where there are no jobs. This is one reason many people migrate to other countries or cities.
In some countries, people are free to live where they want, whereas in some countries the government chooses where people live.
Rural and Urban Settlements
The locations of cities influence how population distributes around the world.
Most of the major cities are on the coasts or near lakes. These cities are typically heavily populated.
Wars have a major influence on population distribution because people flee to areas that are safe.
Population density is the number of people living in an area of land.
Dense Population: more people in a given area
Sparse Population: less people in a given area
Factors that influence population growth:
Modern medicine and hygiene
Industrialization and urbanization
Divide the number of people by the area
Push or pull factor?
How do you find population density?
In Denmark, Copenhagen the population is 5, 250, 000 and the area of the city is
42, 000 km2
What is the population density?
5, 250, 000/42, 000 km2
= 125 people/km2
1. Albania, Tirane
Population = 280, 000
Area = 28, 000km2
2. Bhutan, Thimbu
Population = 1, 500, 000
Area = 50, 000 km2
3. Malta, Valletta
Population = 450, 000
Area = 300 km2
What are the benefits and implications of population growth and decline?
