About this data
- Period life expectancy is the average number of years a person would live if they experienced the death rates of a given year at every age throughout their life. It's a summary of death rates in that year, not a forecast of how long people born then will actually live.
- Figures are for three-year periods, so each area has enough deaths for a reliable estimate. All periods use 2025 local authority boundaries.
- ONS doesn't calculate life expectancy for the City of London or the Isles of Scilly, which have too few residents.
