According to UN DESA’s Population Division, G20 member countries are home to more than 70 per cent of the world’s older population. The number of persons aged 65 or over in G20 countries is expected to grow from 501 million in 2019 to 705 million in 2030, and further to about 1 billion in 2050. The number of persons aged 80 or over in G20 countries is expected to triple during that period, from 102 million in 2019 to 307 million in 2050. In 2019, persons aged 65 or over accounted for 10 per cent of the population living in G20 countries; by 2050, they will represent more than a quarter. The share of “oldest persons” (aged 80+) in the population is increasing rapidly in G20 countries and is expected to reach 15% or more in Japan and the Republic of Korea by 2050.

To support policy makers at all levels to address population ageing, our colleagues at the Population Division released Profiles of Ageing 2019, which present a selection of key ageing indicators for the world, regions and sub-regions, development and income groups, and countries or areas, based on data from World Population Prospects 2019. The related Ten Key Findings offer an overview of ageing trends across G20 Member States.
