Population density refers to the measurement of the number of people living in a given area, usually expressed as the number of people per square kilometer or square mile. It is calculated by dividing the total population of an area by the size of the land area of that region.
Population density can be used to understand the distribution of people in a particular region, and can be a useful tool for understanding social, economic, and environmental issues. High population density areas can face challenges such as overcrowding, resource depletion, and environmental degradation, while low population density areas may face issues such as limited access to services and infrastructure.
