A crude measure of human-land relationship is known as:

The density of population, is a crude measure of human and land relationship.

Physiological density = total population / net cultivated area

Agricultural density = total agricultural population / net cultivable area

Agricultural population includes cultivators and agricultural labourers and their family members
