What this data can and can’t tell you
- The census’s own words. These are self-reported answers: Indigenous identity, immigrant status, religion. The census’s “visible minority” comes from the Employment Equity Act (non-white in colour or race, Indigenous peoples aside), and the page sets each beside other towns without labelling any.
- Against Quebec’s towns and Canada’s towns. Each comparison is its own median: over Quebec’s towns and neighbourhoods of 2,500 or more, and over all Canadian towns of that size (whole cities and First Nations reserves left out). Percentiles are within Canada only.
- What these tables don’t give. Unpaid care, car ownership and internet access aren’t in the Census Profile, nor is the change by age since 2016. Ethnic origins other than visible minority and Indigenous identity are left out of the charts.
