Enter the total number of people and the area in which those people live into the calculator. The calculator will evaluate and display the population density.

## Population Density Formula

The following equation can be used to calculate the population density of an area.

D = P / A

- Where D is the density
- P is the population number
- A is the area

In the the case of population density, we use total number of people per unit area. Normally in math, density is a mass or number per unit volume. When analyzing populations, volumes don’t make much sense to look at, so we use area.

## Population Density Definition

A population density is defined as the total number of people per unit of area.

## Population Density Example

How to calculate population density

**First, determine the total number of people in the area.**Calculate or evaluate the total number of people living in the area you are looking at. This can be done mathematically or by using a physical count.

**Next, determine the total area occupied by those people.**Calculate the total area occupied by the people measured in step 1.

**Calculate the population density.**Using the total number of people and the total area, calculate the population density.

## FAQ

**What is population density?**

Population density is a term used to describe the total number of people that occupy a given unit of area. Typically this unit of area is something like square miles.
