A village of 1,766 in Dyfed, Wales.
Johnston has fewer than 2,500 residents, so it gets subject grades but no overall grade.

Its weakest is safety (D): 63.7 violent and sexual offences and 12.5 home and vehicle crimes per 1,000 residents a year, averaged Sep 2023 to Aug 2026. Among UK towns of 1,000 to 2,500 people, it has less crime per resident than 2%.
Dyfed Powys Police published 32 of the 36 months; rates are per year over the months published. This town's Health Grade uses 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' grades also use OHID's small-area early deaths, hospital admissions and child obesity, which OHID publishes for England only.
