Historians may well conclude that the most
significant event of the 20th century was ...?
the growth of world population.

And in the 21st century, the most significant event

the ageing of humanity.

Population ageing is a triumph of civilization.
It is the inevitable consequence of attaining low levels of fertility and mortality and long life.
However, this achievement requires vital social and economic adjustments to current and expected future demographic realities.
In particular, population ageing raises critical issues for countries, states and cities in areas such as economic growth, employment and retirement, pensions, health care and social support services.
