What this data can and can’t tell you
- 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.
- What these tables don’t give. Missing from the census as published: unpaid care, cars and internet access, and the shift in each age band since 2016. Ethnic origins past visible minority and Indigenous identity aren’t charted here.
