For humans, population density is the number of people per unit of area, usually quoted per square kilometer or square mile. The world’s population is around 7,000,000,000 and Earth’s total area 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).
