This publication presents the highlights of World Population Ageing 2019, which draws on the latest population estimates and projections published in World Population Prospects 2019. This Highlights report provides an overview of key global and regional trends and dynamics of population ageing and discusses different measures of ageing that include conventional measures as well as prospective and economic measures. A set of Annex tables provides global, regional and national data for selected indicators discussed in the report.
In historic first, G20 weighs ageing as global risk
United Nations Population Bulletin, Special Issue Nos. 42/43, 2001
Population ageing is expected to have a major impact on life in the twenty-first century. Concerned by the looming pension crisis, many Governments are promoting more self-reliance in income security for older persons and greater family responsibility for providing care. Consequently, patterns of care-giving and co-residence are emerging as pre-eminent issues related to the well-being of older persons.
The world population is experiencing a historical shift in its age distribution, from the mostly young age structures of the past, towards larger proportions of middle-aged and older persons in the present and future decades. This shift is driven by the demographic transition from high to lower levels of both fertility and mortality. The social and economic consequences of these changes vary greatly across regions and countries.
