UN World Population Ageing: 1950-2050
Population 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.
Population 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.
Population 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.
