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