What this data can and can’t tell you
- What these tables don’t give. Some things the page can’t show: the Census Profile asks nothing about unpaid care, cars or internet access, and gives no change by age since 2016. Ethnic origins beyond visible minority and Indigenous identity aren’t charted.
- The census’s own words. The census takes “visible minority” from the Employment Equity Act: anyone other than Indigenous peoples who is non-white in colour or race. Indigenous identity, immigrant status and religion are what residents reported, compared here with other towns and never used as a label.
- Against Quebec’s towns and Canada’s towns. A figure here is set beside two middles, the median across Quebec’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.
