Population density
To determine an area's population density, you just have to divide an area's total population by the land area in square miles (or square kilometers).

Factors influencing the density and distribution of population
Physical Factors
|
High Density
|
Low Density
|
Relief (shape and height of land) | Low land which is flat e.g. Ganges Valley in India | High land that is mountainous e.g. Himalayas |
Resources | Areas rich in resources (e.g. coal, oil, wood, fishing etc.) tend to densely populated e.g. Western Europe | Areas with few resources tend to be sparsely populated e.g. The Sahel |
Climate | Areas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops e.g. UK | Areas with extreme climates of hot and cold tend to be sparsely populated e.g. the Sahara Desert |
Human Factors
|
High Density
|
Low Density
|
Political | Countries with stable governments tend to have a high population density e.g. Singapore | Unstable countries tend to have lower population densities as people migrate e.g. Afghanistan. |
Social | Groups of people want to live close to each other for security e.g. USA | Other groups of people prefer to be isolated e.g. Scandinavians |
Economic | Good job opportunities encourage high population densities, particularly in large cities in MEDCs and LEDCs around the world. | Limited job opportunities cause some areas to be sparsely populated e.g. Amazon Rainforest |
