The global working age population is shrinking:

The percentage of people aged 15 to 64 in the world population is down -20 points since 1960, to 55%.

Over this period, the sharpest decline was recorded in China, at -36 percentage points, to 44%.

In the US, the working age population proportion fell -13 percentage points, to 54%.

On the other hand, the European Union saw a +2 percentage point increase, to 57%.

Overall, the number of countries where the working age population is shrinking is up by +48 since 1980, to 50.

That number is estimated to increase to 77 by 2040.

Demographics are set to be a major headwind for growth in developed global economies.
