How is physiological density measured? To calculate physiological population density, divide the total population by area of farmland. ( l Physiological Density: calculation of total number of people in a particular geographical area of arable land. p = m V Where: p = density m = mass V = volume The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The ability of the farmland to produce food will be used up more quickly in areas of high physiological density. Therefore, from this very crude type of calculation, the worldwide human population density is approximately 7,800,000,000 510,000,000 = 15.3/km 2 (40 per sq.
