To begin addressing these issues, the General Assembly convened the first World Assembly on Ageing in 1982, which produced a 62-point Vienna International Plan of Action on Ageing. It called for specific action on such issues as health and nutrition, protecting elderly consumers, housing and environment, family, social welfare, income security and employment, education, and the collection and analysis of research data. However, migrants who remain in the country eventually will age into the older population. In countries that are experiencing large immigration flows, international migration can slow the ageing process, at least temporarily, since migrants tend to be in the young working ages.
#WORLD POPULATION THROUGH THE AGES DRIVERS#
While declining fertility and increasing longevity are the key drivers of population ageing globally, international migration has also contributed to changing population age structures in some countries and regions. As the life expectancy at birth increases, improvements in survival at older ages account for a growing proportion of the overall improvement in longevity. The size and age composition of a population are determined jointly by three demographic processes: fertility, mortality and migration.Īll regions have experienced substantial increases in life expectancy since 1950. The number of persons aged 80 years or over is projected to triple, from 143 million in 2019 to 426 million in 2050. In 2018, for the first time in history, persons aged 65 or above outnumbered children under five years of age globally. By 2050, one in four persons living in Europe and Northern America could be aged 65 or over. Globally, the population aged 65 and over is growing faster than all other age groups.Īccording to data from World Population Prospects: the 2019 Revision, by 2050, one in six people in the world will be over age 65 (16%), up from one in 11 in 2019 (9%). In the coming decades, many countries are likely to face fiscal and political pressures in relation to public systems of health care, pensions and social protections for a growing older population. Older persons are increasingly seen as contributors to development, whose abilities to act for the betterment of themselves and their societies should be woven into policies and programmes at all levels.
Population ageing is poised to become one of the most significant social transformations of the twenty-first century, with implications for nearly all sectors of society, including labour and financial markets, the demand for goods and services, such as housing, transportation and social protection, as well as family structures and intergenerational ties. The world’s population is ageing. Virtually every country in the world is experiencing growth in the number and proportion of older persons in their population.
