• People of State Pension age are those at or above it in each year, which has changed over time (see the chart of State Pension age). Working age is 16 to State Pension age.
• Figures to 2025 are calculated from ONS population estimates by single year of age; from 2026 they are ONS's projections, which include planned rises in the State Pension age.
