In this case, which serve as the basis for calculation is the number of farmers and agricultural land available in the area. Agrarian population density can be calculated by the following formula

Agrarian population density (KPA) = (sum of the farming population of an area) / (agricultural land)
Physiological population density
Kepadata physiological population is almost equal to the agrarian population density, because the denominator samam vast agricultural areas. The difference with the agrarian population densities are calculated throughout the region, not just a livelihood as farmers. Thus, physiological population density pedatan using the following formula senagai.
Physiological Population density (KPF) = (number of inhabitants of a region) / (agricultural land)


Arithmetic population density
Type of population density is often used as a measure to calculate the population density of a region or country is the arithmetic population density. To resurrect the population density of an area used arithmetic formula as follows:
Arithmetic population density (kPa) = (number of inhabitants of a region L / P) / (total area in (km / ha))
