What this data can and can’t tell you
- The census’s own words. “Visible minority” is the census’s term from the Employment Equity Act: people, other than Indigenous peoples, who are non-white in colour or race. Indigenous identity, immigrant status and religion are as residents answered. The page compares them with other towns and never labels a town by them.
- Against Quebec’s towns and Canada’s towns. Each comparison is its own median: over Quebec’s towns and neighbourhoods of 2,500 or more, and over all Canadian towns of that size (whole cities and First Nations reserves left out). Percentiles are within Canada only.
- What these tables don’t give. Some things the page can’t show: the Census Profile asks nothing about unpaid care, cars or internet access, and gives no change by age since 2016. Ethnic origins beyond visible minority and Indigenous identity aren’t charted.
