What this data can and can’t tell you
- Against Quebec’s towns and Canada’s towns. For each measure we take the median of Quebec’s towns and neighbourhoods of 2,500 or more, then the median of all Canadian towns. Neither counts whole cities or reserves, and every percentile is a Canadian one.
- 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. These are self-reported answers: Indigenous identity, immigrant status, religion. The census’s “visible minority” comes from the Employment Equity Act (non-white in colour or race, Indigenous peoples aside), and the page sets each beside other towns without labelling any.
