Watch the population grow

Click on the triangular play button to watch world population growth from 1950 to 2050. Adjust the settings to see population plotted against time, track growth by clicking on a ball, or click on the tabs above the graph to see the data in a new way. In 1950 the population of the whole world was just 2.5 billion. It's predicted to climb to over 9 billion by 2050. But where is most of that growth occurring?

As countries become developed, their populations rise. The populations of North America and Western Europe have stayed relatively stable over the last fifty years, and they are predicted to increase slowly over the next fifty. But the populations of developing regions will have increased several times over by 2050. IonE is researching sustainable strategies that these growing populations might use to support themselves.
