For the first time in modern history, the world’s population is expected to virtually stop growing by the end of this century.
As of July 2018, the world’s population is 7.63 billion. More than half of all people around the globe live in just seven countries.
The world was home to nearly half a million people ages 100 and older in 2015, more than four times as many as in 1990. And this growth is expected to accelerate.

The global population is graying and growing rapidly. How big -- and how old -- will it be by 2050?
The population growth in the U.S. and around the world from 1950 to 2010 was rapid—the global population nearly tripled. However, the growth from 2010 to 2050 is projected to be significantly slower and is expected to tilt strongly to the oldest age groups.
