Core housing need is the statutory measure — a home costing more than 30% of before-tax household income, or too crowded, or needing major repairs. Statistics Canada defines it, not us, and the same definition applies to every community in British Columbia.

Denman’s median age is 17.2 years above British Columbia’s 42.8. That cuts two ways and both belong here: it is what a place looks like when working-age families cannot afford to live there, and it is also retirement in-migration, which is a choice people are entitled to make.

One figure we will not dress up

Households here pay an average of $880 a month for shelter.

Average monthly shelter cost is a paid cost, not a measure of affordability: an island of mortgage-free owners and unserviced cabins reports a low one. Publish it as a ratio to income, or beside core housing need, never alone.

Denman against the other islands

Across the 12 Islands Trust local trust areas, 9 have published income figures, and they run from $34,800 on Lasqueti to $78,500 on Salt Spring. Every one has a median age more than thirteen years above the provincial median.

What running your own island costs

Bowen Island incorporated in 1999 and runs its own land use while staying inside the Trust area — the only place in British Columbia that has made the change the abolition campaign asks for. Its 19 years of audited accounts are the only real answer to “what would it cost us?”

Tax per resident went from $839.7 in 2005 to $2,359.73 in 2023 — 2.81 times. Self-government on an island is not cheap. The honest case for it is representation, not savings.

What these figures cannot show

Statistics Canada introduced the designated place in 1996. The Islands Trust was created in 1974. There is therefore no pre-treatment island series, no pre-trend, and no difference-in-differences on the Trust's founding. Any such estimate would be fabricated. The honest window is 2001 onward, and 2006-2021 for the Province's cut.

What we got wrong

Published here at the same prominence as the figures, because a study that only ever confirms its author is not worth reading.

  Withdrawn: “Trust islands are uniformly worse off economically than they would be under ordinary local government — higher costs and lower incomes across the board.”

  It is not uniform, and the Province's own tabulation says so before we published anything. Salt Spring, the largest Trust island, has the HIGHEST median household income in the set at $78,500 and the LOWEST core housing need at 6.0% — better on both than many off-island BC communities. Thetis ($68,500, 8.8%) and North Pender ($67,000, 7.2%) also run against the pattern. The real pattern in the data is a spread, from Lasqueti at $34,800 and 18.2% core need to Salt Spring at $78,500 and 6.0%, and any honest version of this study reports that spread rather than an average. The hypothesis survives only in the specific, weaker form that SOME Trust islands — Denman, Hornby, Lasqueti — show high core housing need alongside low income, and even there the cause is not established.

  Withdrawn: “A fifty-year economic history of the Trust islands, measuring what changed after the Trust was created in 1974.”

  Cannot be built, and the reason is structural rather than a matter of effort. Statistics Canada introduced the designated place in 1996, twenty-two years after the Islands Trust Act. There is no island-level census geography before then, so there is no pre-treatment series, no pre-trend to fit, and no difference-in-differences on the founding of the Trust. Pre-1996 material exists only as historical census geography products reachable through a university data-library affiliation or a direct request to StatCan, and we hold none of it. The study is therefore a documented series from 2001/2006 onward, and the pages must not imply a before-and-after that the data cannot support. This removes the strongest claim the campaign could have made from this work.
