Earth has become small for humanity.
The world's population is around 7,500,000,000 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 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi). If only the Earth's land area of 150,000,000 km2 (58,000,000 sq. mi.) is taken into account, then human population density is 50 per km2 (129 per sq. mile).
