Population distribution and physiological density help geographers to determine how much land is needed to support any given population and to account for discrepancies between the number of people and available land. These concepts allow geographers to analyze how population relates to land use, resources, and sustainability in various regions.

If the physiological density in a given country is very high and its arithmetic density is very low, then a country has too many people for the available resources, particularly in regards to agricultural land. This suggests that while there may be a lot of space (as indicated by low arithmetic density), the land that is suitable for agriculture is limited, leading to a high physiological density that points to pressure on agricultural resources.

An increase in a country’s agricultural density would suggest a(n) decrease in the amount of agricultural land. Agricultural density is calculated by dividing the number of farmers by the amount of arable land. Therefore, if agricultural density increases, it typically means that there are more farmers relative to the amount of agricultural land available, indicating that the amount of agricultural land has likely decreased.
