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.
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.
