What this data can and can’t tell you
- Against Quebec’s towns and Canada’s towns. For each measure we take the median of Quebec’s towns and neighbourhoods of 2,500 or more, then the median of all Canadian towns. Neither counts whole cities or reserves, and every percentile is a Canadian one.
- 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.
