Important terms on Human Resources
Human resource: Human resource is the ultimate resource. Healthy, educated and motivated people develop resources as per their requirements. Human resources like other resources are not equally distributed over the world. They differ in their educational levels, age and sex. Their numbers and characteristics also keep changing. The way in which people are spread across the earth surface is known as the pattern of population distribution. More than 90 per cent of the world’s population lives in about 10 per cent of the land surface. The distribution of population in the world is extremely uneven.
Population density is the number of people living in a unit area of the earth’s surface. It is normally expressed as per square km. The average density of population in the whole world is 45 persons per square km. South Central Asia has the highest density of population followed by East and South East Asia.
