Service life
Years in service. The band runs from the shortest to the longest life the sources state, so it shows how much they disagree, not how long 80% of units last. The line is the median of the stated lives.

Municipal lives for electrical (D50)
35 municipalities in Ontario, British Columbia and Alberta state a life for electrical as a whole, in 27 distinct tables: 10–50 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.
