What this data can and can’t tell you
- 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. 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. “Visible minority” is the census’s term from the Employment Equity Act: people, other than Indigenous peoples, who are non-white in colour or race. Indigenous identity, immigrant status and religion are as residents answered. The page compares them with other towns and never labels a town by them.
