This report was prepared by the
Population Division as a contribution to the 2002 World Assembly
on Ageing and its follow-up. The report provides a description
of global trends in population ageing and includes a series
of indicators of the ageing process by development regions,
major areas, regions and countries. The
report shows that:
ageing is unprecedented, without parallel in human history—and the twenty-first century will witness even more rapid ageing than
did the century just past.
ageing is pervasive, a global phenomenon affecting every man, woman and child—but
countries are at very different stages of the process, and the
pace of change differs greatly. Countries that started
the process later will have less time to adjust.
ageing is enduring: we will not return to the young
populations that our ancestors knew.
Population ageing has profound implications for many facets of human life.
