A population density map is used to visually represent the distribution and concentration of people in a given area. It provides a clear and intuitive representation of the number of people living in different regions, allowing users to quickly identify areas with high population density and areas with lower population density. This information is valuable for various purposes, such as urban planning, resource allocation, and understanding patterns of human settlement.
