What Was the Population of the World in 1900?

According to the U.S. Census Bureau, the estimated population of the world in 1900 was between 1.55 billion and 1.762 billion people. Since then the world population has grown to about 7.2 billion people.

In 1900 Asia held 57.4 percent of the world's population. Europe had 24.7 percent, making it the second-most populated area. In distant third, with 8.1 percent, was Africa, followed by North America at 5 percent and Latin America with 4.5 percent. Oceania was in last place with 0.4 percent of the world's population. As of 2014, the balance has shifted slightly. Asia's share of total population is declining slowly, while Africa's is rising. Europe's has declined by more than half, while Latin America's has nearly doubled. North America and Oceania's shares have stayed roughly even.
