What this data can and can’t tell you
- 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. Provincial and national yardsticks: Quebec’s towns and neighbourhoods of at least 2,500 residents, and all Canadian towns of that size. No whole city and no First Nations reserve is in either median.
- 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.
