Consider the following statements on computation of density:

  • 1. Physiological density can be computed by dividing the total population by the net cultivable area.
  • 2. Agricultural density can be computed by dividing the total agricultural population by the net cultivable area.
  • 3. Population density can be computed by dividing the total population by the total area.

All three statements correctly define different types of population density computations.
1. Physiological density is indeed calculated by dividing the total population by the net cultivable area. This gives an idea of the pressure on arable land for food production.
2. Agricultural density is calculated by dividing the total agricultural population (farmers, farm workers, and their dependents) by the net cultivable area. This measures the number of people engaged in agriculture per unit area of arable land.
3. Population density (or Arithmetic density) is the most basic measure, computed by dividing the total population by the total land area. This indicates the average number of people per unit area.
Different measures of density provide varying insights into the relationship between population and land, highlighting aspects like resource pressure, agricultural efficiency, or simple spatial distribution.
While population density gives a general sense of crowding, physiological and agricultural densities are more specific measures related to agricultural capacity and rural population dynamics. Other density measures exist, such as urban density, which considers only urban areas.
