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. How many of the above statements is/are correct?

All three statements are correct based on standard geographical definitions. Physiological density is calculated by dividing the total population by the net cultivated or arable land area [1][2]. This measure provides a more realistic index of population pressure on food-producing land compared to simple arithmetic density [1][3]. Agricultural density is defined as the ratio of the total agricultural population (which includes cultivators, laborers, and their families) to the net cultivable area [1][2]. Finally, population density (specifically arithmetic density) is the most common measure, computed by dividing the total population by the total land area [4]. These metrics are essential for understanding the human-land ratio and the intensity of land use in agrarian economies like India [3].
