The aging of the world is not news, but visualising the change is done very well here:
Population By Age, Japan
Population By Age, U.S.
Not all countries are getting older. Many developing countries still have high fertility rates, and children account for a huge share of the people in those countries. (Typically, fertility rates don’t start falling until countries hit a certain stage of economic development.)
When you look at the whole world, you see a blend of these two trends — the population of the globe is aging, on average, but there are still far more children than old people.
