About this data

Source: UN, World Population Prospects 2024 (medium variant)

• Worked out from the UN's population estimates and projections by age, using the OECD's definition (65 and over, per 100 aged 20 to 64). Projections from 2024 are the UN's medium variant.
• The OECD average is the average of its 38 member countries.
• The ratio is a simple guide to the number of older people relative to people of working age. It doesn't account for how many people actually work, or for changing pension ages.
