Using data from the CIA Factbook, Global Post created graphics to visualize the median age of every country in the world. The world's 15 youngest countries are all in Africa.
There are 1.2 billion people between the ages of 15 and 24 in the world today — and that means that many countries have populations younger than ever before.
Some believe that this "youth bulge" helps fuel social unrest — particularly when combined with high levels of youth unemployment. Writing for the Guardian last year, John Podesta, director of the progressive Center for American Progress, warned that youth unemployment is a "global time bomb," as long as today's millennials remain "hampered by weak economies, discrimination, and inequality of opportunity."
