What this data can and can’t tell you
- 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. The Census Profile has no unpaid care, cars or internet access, and no change by age since 2016; ethnic origins beyond visible minority and Indigenous identity aren’t charted here.
- The census’s own words. In the census, “visible minority” is the Employment Equity Act’s term for people who are non-white in colour or race and not Indigenous. Like immigrant status, Indigenous identity and religion, which residents reported themselves, it is compared with other towns, never turned into a label.
