Population density is a measure of the number of individuals in a population relative to the unit of area or volume they occupy. The formula for calculating population density is individuals per unit area or individuals per unit volume. The units of population density can vary, such as people per square kilometer or organisms per cubic meter. Population density is influenced by factors such as the size of the population, the geographical area it inhabits, and the distribution of individuals within the area.
Formula for Population Density
Population density is a measure of how many people live in a particular area. It is calculated by dividing the number of people in an area by the total land area of that area. The formula for population density is:
Population density = Number of people / Total land area
The result of this calculation is typically expressed in units of people per square kilometer or people per square mile.
How to Calculate Population Density
To calculate population density, you will need to know the total number of people in an area and the total land area of that area. Once you have this information, you can simply divide the number of people by the land area to get the population density.
For example, if there are 100 people living in an area with a total land area of 1 square kilometer, the population density would be 100 people per square kilometer.
Factors that Affect Population Density
There are a number of factors that can affect population density, including:
- The size of the area. The larger the area, the lower the population density.
- The availability of resources. Areas with more resources, such as water and food, tend to have higher population densities.
- The climate. Areas with more favorable climates tend to have higher population densities.
- The economy. Areas with strong economies tend to have higher population densities.
- The political system. Areas with stable political systems tend to have higher population densities.
Table of Population Densities

| Antigua and Barbuda | 191 |
Question 1: How is population density calculated?
Answer: Population density is calculated by dividing the total population of an area by the total land area of that area. The result is expressed as the number of people per unit of land area, such as people per square kilometer or people per square mile.
Question 2: What is the formula for population density?
Answer: The formula for population density is:
Population density = Total population / Total land area
Question 3: What factors affect population density?
Answer: Population density is affected by a variety of factors, including the availability of resources, the level of economic development, the rate of urbanization, and the physical characteristics of an area.
