This town's rent is the 2021 census rent scaled to 2025 by its province's ratio of surveyed to census rents: no rental survey covers it, so its Cost Grade is less sure. Safety less sure: no police service names this town, so its crime figure is the nearest police detachment's, shared with a wider area. Health is graded on the health region's survey figures and life expectancy, with the distance to hospital giving the town its own spread.
