Population density is a statistic that tells you how many people live in a certain area. ...

What is arithmetic densities?

How do you find the arithmetic population density?

Arithmetic Density

One can find this by dividing the total number of people in an area by the total land area. For example, to find the arithmetic density for the US, you divide the amount of people (300 million) by the amount of land (3.7 million square miles) and you get 80 people per each square mile.
