There are a range of human and natural factors that affect population density. The tables below illustrate this.
(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|
|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|
