Population ageing is a phenomenon that occurs when the median age of a country or region rises due to rising life expectancy and/or declining birth rates. There has been, initially in the more economically developed countries ( MEDC ) but also more recently in LEDCs ( less economically developed countries ), an increase in the life expectancy which causes ageing population. This is the case for every country in the world except the 18 countries designated as "demographic outliers" by the UN. For the entirety of recorded human history, the world has never seen as aged a population as currently exists globally. The UN predicts the rate of population ageing in the 21st century will exceed that of the previous century. Countries vary significantly in terms of the degree, and the pace, of these changes, and the UN expects populations that began ageing later to have less time to adapt to the many implications of these changes.

Famous quotes containing the words population and/or ageing:
“In our large cities, the population is godless, materialized,—no bond, no fellow-feeling, no enthusiasm. These are not men, but hungers, thirsts, fevers, and appetites walking. How is it people manage to live on,—so aimless as they are? After their peppercorn aims are gained, it seems as if the lime in their bones alone held them together, and not any worthy purpose.”
—Ralph Waldo Emerson (1803–1882)
“Our civilization survives in the complacency of cowardly or malignant minds—a sacrifice to the vanity of ageing adolescents.... In 1953, excess is always a comfort, and sometimes a career.”
—Albert Camus (1913–1960)
