A population map is used to represent the overall distribution of population within a particular area. Most maps represent the varying population data using color, while other population maps use symbols, such as circles or stars.
Some population maps also include the water bodies found in the region. Population maps typically focus on the population density in cities, towns, states and countries. A population map that shows the varying population densities across the world is referred to as a world population map.
Researchers and students are able to understand the overall distribution of population density across the globe using population maps. Population maps are also used by central governments to plan and distribute resources.
