What this data can and can’t tell you
- Against Ontario’s towns and Canada’s towns. Each comparison is its own median: over Ontario’s towns and neighbourhoods of 2,500 or more, and over all Canadian towns of that size (whole cities and First Nations reserves left out). Percentiles are within Canada only.
- 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.
