Population Ages

According to the United Nations Educational, Scientific, and Cultural Organization (UNESCO), as of 2012, 50.5 percent of the world's population were people under the age of 30. Around 89.7 percent of those young people live in emerging and developing economies like the Middle East and Africa.

People 60 years and older make up 12.3 percent of the global population.

Although the majority of the human population is currently under 30 years old, there are still plenty of older folks among us. In fact, 12.3 percent of people on Earth are 60 years old and older. That number is expected to reach 22 percent by 2050.
