Count on the list: 1, each born in Electoral Area A, Cowichan Valley according to Wikidata and an English or French Wikipedia article. Wikidata places 2 here in all, and those missing from the list lack a confirming article.
The largest group is soldiers and sailors, 1 in all out of 1. 100% of the list, where Canadian towns come to 2%.
Anyone Wikidata records as born at a place inside Electoral Area A, Cowichan Valley’s municipal boundary (Statistics Canada’s 2021 census subdivision), hospitals and districts within it included, whose English or French Wikipedia article confirms it. People who only lived here, adult performers and people known mainly for crimes are left out.
Some have no birthplace below the province on Wikidata, some were born in a hamlet without a page here, and some have an article that names another place or none at all. The page lists only what Wikidata and Wikipedia agree on, and it follows their corrections at each refresh.
Birthplaces, descriptions, years, occupations and the count of Wikipedia and sister-site articles come from Wikidata (CC0). Each birthplace is checked against the person’s English Wikipedia article, or the French one where English says nothing or has no article; the articles are linked, never quoted. Wikidata’s Statistics Canada code, the place’s name or its point inside the 2021 census outline puts a birth in a town, and a birth given only as a split city stays on that city’s page. Fields are read from the description and occupations, and the list runs by number of articles. “The usual town” is everyone listed across Canadian towns.
