Municipal lives for fire protection (D40)

16 municipalities in British Columbia and Ontario state a life for fire protection as a whole, in 10 distinct tables: 15–50 years, median 20. These come from capital asset policies: accounting lives, used for amortization. They describe the system rather than this component, and none is a measured life.

Years. Each dot is one stated life and each bar a stated range; equal values stack. The dashed line is the median. Policies that copy the same table count once.
