Population density can be defined as the total number of people who live in each square kilometer of land.
Population density is measured by "dividing the number of people by the area of land they live in".
For instance, if the population of country A is 900,000 and country A is 300 square kilometer.
Therefore,
Population density of country A = Total population of country A ÷ Total land area
= 900,000 / 300
= 3,000 people per square kilometer.
