Unit 8: Population - Population density

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 IndiaHigh land that is mountainous e.g. Himalayas
ResourcesAreas rich in resources (e.g. coal, oil, wood, fishing etc.) tend to densely populated e.g. Western EuropeAreas with few resources tend to be sparsely populated e.g. The Sahel
ClimateAreas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops e.g. UKAreas with extreme climates of hot and cold tend to be sparsely populated e.g. the Sahara Desert

Human Factors
High Density
Low Density
PoliticalCountries with stable governments tend to have a high population density e.g. SingaporeUnstable countries tend to have lower population densities as people migrate e.g. Afghanistan.
SocialGroups of people want to live close to each other for security e.g. USAOther groups of people prefer to be isolated e.g. Scandinavians
EconomicGood 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
