The world has passed “peak child”

The number of children in the world has stopped growing. This moment in time was given the term “peak child” by the late Hans Rosling.

The chart shows the estimated number of children under five years old globally up to 2023, with projections from the United Nations out to 2100. The UN thinks the number of under-5s peaked in 2017.

The chart also shows the number of young people under 15, which peaked in 2021. And the number of under-25s, which may have peaked last year.

“Peak child” is a sign that the world is on course for “peak population”. The UN expects the world population to start falling before the end of the century.
