📘 About the Population Density Calculator

Population density is the number of people per unit of area. India, with about 1.45 billion people on 3.29 million km², has about 440 people per km² — eight times the world average and more than three times China's. Singapore, Hong Kong and Bangladesh are even denser.

Choose a country to see its density, population, area, space per person and rank, with a sortable table of 60 countries. Or enter the population and area of your own city, district, housing society or plot.
