Visualizing How A Population Grows To 7 Billion
7 Billion: How Did We Get So Big So Fast? Watch as global population explodes from 300 million to 7 billion. Sometime Monday, the world will have more humans than ever: 7 billion, according to the U.N. The U.N. estimates that the world's population will pass the 7 billion mark on Monday. Much of that growth has happened in Asia — in India and China. Those two countries have been among the world's most populous for centuries. Due in part to that region's extreme poverty, infant mortality rates are high and access to family planning is low. As NPR's Adam Cole reports, it was just over two centuries ago that the global population was 1 billion — in 1804. As higher standards of living and better health care are reaching more parts of the world, the rates of fertility — and population growth — have started to slow down, though the population will continue to grow for the foreseeable future.
