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. Not in the Census Profile: unpaid care, cars, internet access, and how each age group has changed since 2016. We also chart no ethnic origins besides visible minority and Indigenous identity.
- 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.
