The reason is that population density is actually a broader category of understanding the amount of people in a given area, while physiological density is one of three different methods of doing just that. As a result, most people refer only to population density and not the method used to understand it. To understand a physiological density definition, lets look at an example. Well give you challenging practice questions to help you achieve mastery in AP Human Geography. It is more reflective of population pressure on arable land. Meanwhile, agricultural population density considers the ratio of farms (and/or farms) to arable land.

The different types of density are each important to understanding a specific area of the world, but physiological density is often considered real population density because it provides a better understanding and overview of the country it relates to. Seven maps/datasets for the distribution of various populations It all makes perfect sense once you realize we are measuring physiological population density and not arithmetic population density. In these countries, farmland is more plentiful than in many of the higher density countries, which tend to have more urban areas and a lot less farmland.
