Population density For humans, population density is the number of people per unit of area, usually quoted per square kilometer or square mile (which may include or exclude, for example, areas of water or glaciers). Commonly this may be calculated for a county, city, country, another territory, or the entire world. The world's population is around 7,000,000,000 and Earth's total area (including land and water) is 510,000,000 square kilometers (197,000,000 sq. mi.). Therefore, the worldwide human population density is around 7,000,000,000 ÷ 510,000,000 = 13.7 per km2 (35 per sq. mi).
