Population ageing is pervasive, a global phenomenon affecting every man, woman and child. The steady increase of older age groups in national populations, both in absolute numbers and in relation to the working-age population, has a direct bearing on the intergenerational and intragenerational equity and solidarity that are the foundations of society.
Population ageing is profound, having major consequences and implications for all facets of human life. In the economic area, it will have an impact on growth, savings, investment and consumption, labour markets, pensions, taxation and intergenerational transfers. In the social sphere, population ageing affects health and health care, family composition and living arrangements, housing and migration. In the political arena, ageing can inﬂuence voting patterns and representation.
