Population Density Calculator, Formula, Population Density Calculation

Population Density Calculator:

Enter the values of population, P and area, A_(km2) to determine the value of Population density, D.

Population Density Formula:

Population density (D) measures the number of people living in a given unit of area, typically expressed as individuals per square kilometer or square mile.

It provides insight into how crowded a place is, indicating the average concentration of people in a specific region.

Higher population density can imply greater demand for resources and services, while lower density might indicate more available space per person.

A larger population in a fixed area will lead to a higher density (D).

A smaller area (A) with the same population (P) will result in a higher density (D) because more people are crammed into a smaller space.

Population density, D in people per square kilometre is calculated by dividing the total population, P by the total land area, A_(km2) in square kilometre.

Population density, D = P / A_(km2)

D = population density in people per square kilometre.

P = population.

A_(km2) = area in square kilometre, km².

Population Density Calculation:

1. A city has a total population of 500,000 people and covers an area of 250 square kilometers. Calculate the population density.

Given: P = 500000, A_(km2) = 250km².

Population density, D = P / A_(km2)

D = 500000 / 250

D = 2000.

2. A region has a population density of 1,500 people per square mile and a total population of 450,000 people. Calculate the area.

Given: P = 450000, D = 1500.

Population density, D = P / A_(km2)

A_(km2) = P / D

A_(km2) = 450000 / 1500

A_(km2) = 300km².
