What factors affect population density and distribution?
Population distribution is a term used to describe how humans are spread across the Earth. Population distribution across the Earth is uneven. Some areas are densely populated, whereas others are sparsely populated.
The land surface of the Earth accounts for around 30% of its area. However, only around 11% of the land surface can be comfortably inhabited by humans. Many human and physical factors affect population distribution and population density across the world.
Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.
Human factors that affect population density include social, political and economic factors.
