Population Density and Distribution
Humans are the ultimate resource of nature, and are referred to as human resources. In India, a Ministry of Human Resource Development was created in 1985 with the primary purpose of ensuring that the people of India are healthy, educated and motivated. The pattern in which people are spread across the earth is known as population distribution. The number of people living in a unit area of the earth’s surface gives the density of population. Population density is calculated by dividing the number of people by area and is usually expressed as the number of people per square kilometre. The average density of population in the whole world is 45 persons per square kilometre. The population density of a place depends on a range of geographical and socio-economical factors. The topography of a place, its climate and availability of resources like water, soil, minerals, social, cultural and economic factors are some geographical factors that affect the population of a place.
