Welsh towns’ Health Grades use ONS’s small-area life expectancy and healthy life expectancy for 2019 to 2023, and two Census 2021 measures, bad health and disability, adjusted for age. English towns’ also use OHID’s small-area early deaths, hospital admissions and child obesity, which OHID publishes for England only.
