Where People Live on Planet Earth
Explanation: Where do people live on Planet Earth ? Although people inhabit every continent , the highest population densities occur in Asia . Sparsely inhabited regions occur on virtually every continent, however, including the Sahara Desert in Africa , the Great White North of North America , the outback of Australia , the Amazon of South America , and the Himalayan Mountains of Asia . The above color-coded map was produced from populations estimates made for 1994, when the world population was about 5.5 billion. Current estimates place the world population at about 6.3 billion.
