SHOW is an online informational tool launched in May 2008 by Mapping Worlds under the age of 15. The website offers users a new way to look at the world by resizing countries on the map according to a series of global issues.
In this interactive map SHOW breaks down the ten largest youth populations. The current crop of children is the largest in world history. However, the global baby boom is slowing, and total births are projected to begin falling in 2030.
Fertility is already falling in many developed countries, but the decline is offset somewhat by immigration. Three of every ten people in India is under 15; in Africa, four of every ten.
