What can we deduce from looking at a countrys physiological density? To put this concept into numbers, the United States has a physiological density of 179, whereas Djibouti, in the Middle East, comes in at 131,101. This statistic is probably the most general and least useful of the three measures of population density.

By better understanding the amount of food that is being used in any given area or the amount of food that may be still needed in order to support the people already living there and the total amount of people and the total amount of land, we can better understand (approximately) how crowded the people are in the country.

Arithmetic Density: basic calculation of total number of people living in a particular geographical area of land. Also known as real density. Physiological Density: calculation of total number of people in a particular geographical area of arable land.

For the AP Human Geography Exam, it is also important to know how to calculate population density and the implications it has on society and the environment.

Many people know what it means to refer to population density, but few have actually heard the term physiological density.

Physiological Density. 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. (the pattern in which people live) with its density. To understand why people live in the concentrations they do, you need to understand that only part of our planet is fit for human habitation.

C!



Density-dependant factors can have either a positive or a negative correlation to population size. You can have an area of high population density but is not considered overcrowded if the area has a high carrying capacity. It measures the total number of people and divides them between the total amount of farmable land. On the other extreme, the hundred least densely populated districts, covering nearly a quarter of the total geographic area, account for only 5 per cent of the countrys population.
