What this data can and can’t tell you

- 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.
