About this data

Source: ONS, Population estimates for the UK, mid-2025 (via Nomis)

• Local authorities as they were in April 2023; earlier years' estimates are given for today's areas.
• Dependency ratios compare the number of children (aged 0 to 15) and older people (aged 65 and over) with the number of people of working age (16 to 64). They are a rough measure: many people aged 16 to 64 aren't working, and many people over 65 are. ONS's own old-age dependency ratio uses the State Pension age rather than 65, so it is lower.
