What this data can and can’t tell you
- Against Ontario’s towns and Canada’s towns. A figure here is set beside two middles, the median across Ontario’s places of 2,500 people or more and the median across all Canadian towns that size; reserves and entire cities are excluded from both.
- 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. In the census, “visible minority” is the Employment Equity Act’s term for people who are non-white in colour or race and not Indigenous. Like immigrant status, Indigenous identity and religion, which residents reported themselves, it is compared with other towns, never turned into a label.
