The World Factbook

The World Factbook contains descriptions of the population distribution for the World, countries, and territories. Globally, six of the world's seven continents are widely and permanently inhabited. Asia is easily the most-populous continent with about 60% of the world's population (China and India together comprise over 35%), while Africa comes in second with over 15% of the earth's populace. Europe accounts for about 10%, North America 8%, South America almost 6%, and Oceania less than 1%. The harsh conditions on Antarctica prevent any permanent habitation.
