What this data can and can’t tell you
- What these tables don’t give. For origins the charts stop at visible minority and Indigenous identity, and the Census Profile has nothing on unpaid care, cars or the internet, or on change by age since 2016.
- 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.
- Against Ontario’s towns and Canada’s towns. For each measure we take the median of Ontario’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.
