What is arithmetic density of population?

Arithmetic density of population is the number of all people that live in a "per unit area" throughout a country, and it can be referred to as the "crude density" or "regular density." An example of an arithmetic population density that is much higher than normal can be found in Japan, where there are areas with more than 1,400 people per square mile.

Population geography is one discipline that uses arithmetic density to help determine the growth trends throughout the world's population. The field of population geography seeks to understand how many human beings there are in various places as well as how their health conditions, socioeconomic levels and food supply levels measure up.
