Is Duncan a good place to live?

More weak spots than strong ones. Prices are high against local incomes (D−). Its strongest subject is walkability (A+). Overall, that makes a D−, good for #245 of 250 in British Columbia. That leaves it behind almost every Canadian town. It lags on safety as well (D−). Its remaining grades are unremarkable: B for health and B− for hazard risk.

Health is graded on the health region's survey figures and life expectancy, with the distance to hospital giving the town its own spread.

How Duncan grades

Each subject compares Duncan with Canadian towns of 2,500 or more, ordered by how far it is from the middle. Towns in other countries are graded separately.
