Who is counted? Ethno-racial and indigenous identities in the Census of Canada, 1871-2021

Finding data on race, racialized populations, and anti-racism in Canada can be a complex process when conducting research. One source of data is the Census of Canada which has been collecting socio-demographic data since 1871. However, the collection of racial, ethnic, or Indigenous data has changed throughout the years and from Census to Census. In response to the need for more support in finding ethno-racial and Indigenous data, the Ontario Council of University Libraries’ Ontario Data Community has created an online guide to provide guidance, in part, about the terminology used for Indigenous and racialized identities over time in the Census. In this article, the modifications to how ethno-racial origin questions have been asked, and the ongoing changes to sociocultural perceptions impacting the Census are reviewed.
