What this data can and can’t tell you
- 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. 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.
- 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.
