Population Density - IB Geography Definition

What is population density?

In IB Geography, population density is a measure that expresses the number of people living in a specific unit area, typically per square kilometre. It is a key concept in understanding spatial distribution in geography.

Population density calculations allow students to analyse how populations are spread across the Earth's surface and can reveal patterns of settlement and resource utilisation. A high population density might indicate urban areas with limited space but abundant resources and infrastructure, while low density often characterises rural regions with more space but potentially fewer resources and services.

Understanding population density helps students explore the implications of human habitation concerning environmental sustainability, economic development, and social cohesion, which are crucial aspects of the IB Geography course.
