World Population Ageing 2019
By United Nations
1. Population ageing is a global phenomenon: Virtually every country in the world is experiencing growth in the size and proportion of older persons in their population. There were 703 million persons aged 65 years or over in the world in 2019. The number of older persons is projected to double to 1.5 billion in 2050. Globally, the share of the population aged 65 years or over increased from 6 per cent in 1990 to 9 per cent in 2019. That proportion is projected to rise further to 16 per cent by 2050, so that one in six people in the world will be aged 65 years or over.
2. Population ageing has been fastest in Eastern and South-Eastern Asia and Latin America and the Caribbean. The percentage of the population aged 65 years or over almost doubled from 6 per cent in 1990 to 11 per cent in 2019 in Eastern and South-Eastern Asia, and from 5 per cent in 1990 to 9 per cent in 2019 in Latin America and the Caribbean. Between 2019 and 2050, the share of older persons is projected at least to double in four regions: Northern Africa and Western Asia, Central and Southern Asia, Latin America and the Caribbean, and Eastern and South-Eastern Asia.
