Each edition grades its towns against each other only.
Home to 5,264 people, this town lies in Gwynedd, Wales.
Low prices, and some weak spots to weigh against them. Safety lags: police record 53.5 violent and sexual offences per 1,000 residents a year, and 12 home and vehicle crimes. Against UK towns of 2,500 to 10,000 people, it has more crime per resident than 93%. It lags on jobs & income as well — the mean household earns £47,076 a year. Where it does best is cost of living (A) — homes sell for a median £207,500, about 4.6 times local household income. Overall, that makes a C, better than 30% of UK towns. That places it #8 of 13 in Gwynedd.
