The formula for population density is Dp= N/A, where Dp is the population density, N is the total population, and A is the land area covered by the population. For human populations, A is typically expressed as square miles or square kilometers.
The population density of a country or city or other place is a number showing how crowded that place is. ... For example, France has a population of 60,561,200, and an area of 551,695 square kilometres, so its population density is about 109.8 persons per square kilometre.
