What this data can and can’t tell you
- Against Quebec’s towns and Canada’s towns. A figure here is set beside two middles, the median across Quebec’s places of 2,500 people or more and the median across all Canadian towns that size; reserves and entire cities are excluded from both.
- What these tables don’t give. Not in the Census Profile: unpaid care, cars, internet access, and how each age group has changed since 2016. We also chart no ethnic origins besides visible minority and Indigenous identity.
- 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.
