A population density map is used to define as a map that shows the presence of a number of the population existing in any particular area. It directly reflects the dispersion of people that are mainly affected by environmental factors. This includes the variable amount of natural resources present in that area, the type of climate prevailing, the topography of the area and the availability of water resources.
The places which are rich in resources and low lying areas, with plenty of water resources and moderate type of climate are comprised of high-density population. On the other hand, the places which are highly elevated, lack of resources and extreme cold and hot climate are comprised of a lesser population.
