Inverse population density is when the population density decreases, the population growth rate also decreases. This is opposite to density dependent because here the population growth rate decreaes as population density increases.

A density independent factor affects the members of a population regardless of population density, whereas a Density dependent factor affects a population because of the density of the population.

There are two measures of population density. Arithmetic (or crude) population density is simply population/area, giving you x people per square ______. Physiological density is population/arable (farmable) land.
