What this data can and can’t tell you
- 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 New Brunswick’s towns and Canada’s towns. A figure here is set beside two middles, the median across New Brunswick’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.
