More people report bad health than its ages predict

Trethomas grades D for health
Healthier than 14% of UK towns, on age-adjusted measures.
Behind the typical UK town on every measure. Even its strongest, women’s life expectancy and men’s life expectancy, are in the bottom 40% of UK towns; Census bad health and disability are furthest behind.
Each measure is ranked against every UK town of 1,000 or more, the ranks are averaged, and the average is ranked again. Every measure allows for the town’s ages: life expectancy is worked out from the death rate at each age, so it doesn’t depend on how old the town’s residents are; the Census answers are counted against what England and Wales’s rates by single year of age would give a town with these ages, so a seaside town of retired people isn’t marked down for being old.
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.
Fewer people in Trethomas call their health good than across Gwent
Census 2021, all residents, as answered (not adjusted for age).
Trethomas’ residents are younger than Gwent’s (14% are 65 or over, against 20%), which accounts for much of the difference. Adjusted for age, 215 report bad health for every 100 expected, more than the national rate.

What this data can and can’t tell you
- Adjusted for age. A ratio of 100 means as many deaths, admissions or reports of bad health as England’s rates (England and Wales’s for the Census) would give a town with these ages; 120 means a fifth more.
- Small areas, summed to the town. The Census measures are counted for the town’s own output areas.
- Different years. The Census was taken in March 2021. NHS sites are as listed by NHS Wales in October 2026.
- Distances are straight lines. Miles are measured from the town’s centre to each site; the road is longer. For an emergency, call 999; for urgent advice, call NHS 111.
