This graph tracks world population growth on each of the six inhabited continents by decade, from 1970 through 2010.
Asia’s population is the highest, starting at over 500 million in the 1970s, and growing to well over 600 million by 2010. Asia is followed by Africa, moving from under 200 million people to nearly 300 million. Neither Europe, America, and nor Oceania reach populations of 200 million in any decade, although all experience the same upward trend as Asia and Africa from 1970 to 2010. Oceania’s population is by far the smallest.
With respect to the rates at which these populations are growing, Europe appears to be increasing fastest, having nearly doubled from just over 100 million in 1970 to nearly 200 million. A slight divergence between Europe and America is observable, indicating that U.S. population growth rates are lower than European growth rates. The gap between Asia and Africa is also increasing.
