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. Indigenous identity, immigrant status and religion are as residents answered them. “Visible minority” follows the Employment Equity Act, meaning people other than Indigenous peoples who are non-white in colour or race. We compare these figures across towns; none is a label for a town.
