What is Population Distribution & Population Density?

Population distribution describes how people are spread out across a particular area, which can be even or uneven. Population density is the measurement of the number of people in an area, calculated by dividing the total population by the area in square kilometres. These patterns are influenced by physical factors, such as climate and relief, and human factors, like economic opportunities and political stability.

Board notes: This is a foundational concept in human geography for all exam boards (AQA, Edexcel, OCR). Students need to be able to describe global patterns of population distribution and explain the physical and human factors that cause them, using named examples.

Worked example

Common mistakes

• 1Using distribution and density interchangeably. Distribution is a qualitative description of the spread (e.g., 'clustered along the coast'), while density is a quantitative measurement (e.g., '250 people per km²').
• 2Assuming high population density is always a bad thing. Cities like Singapore and Hong Kong have extremely high densities but also very high standards of living. Density can facilitate economic efficiency and the provision of public services.
• 3Forgetting that population density is an average. A country might have a low overall density, but have areas of very high density within it, for example, Egypt has a low national density, but 95% of its population lives in a narrow band along the Nile River.

Frequently asked questions

• Why are some areas of the world sparsely populated?

  Areas are sparsely populated if the physical environment is challenging, for example, due to extreme climates (hot deserts, polar regions), mountainous terrain (the Himalayas), or dense vegetation (Amazon rainforest). These areas often lack economic opportunities.

• Why are some areas of the world densely populated?

  Areas are densely populated where the physical environment is favourable, such as flat, fertile river valleys (the Ganges in India) and coastal plains. Human factors are also crucial, including the presence of cities, trade routes, and economic development.
