What this data can and can’t tell you
- What these tables don’t give. Unpaid care, car ownership and internet access aren’t in the Census Profile, nor is the change by age since 2016. Ethnic origins other than visible minority and Indigenous identity are left out of the charts.
- 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. The middle of Quebec’s towns of 2,500 or more comes first, the middle of all Canadian towns second; cities as a whole and First Nations reserves stay out, and percentiles are within Canada.
