When studying official language minorities, researchers or organizations working in minority settings often wonder what language variable they should use. The Canadian Institute for Research on Linguistic Minorities has produced three reports aimed at defining the minority Francophone population based on language data from the Statistics Canada 2001, 2006 and 2011 Censuses (Forgues and Landry, 2006; Forgues, Landry and Boudreau, 2009 and Guignard Noël, Forgues and Landry, 2014). In this report, the authors updated these analyses with data from 2016 and added data on English-speaking Quebeckers in order to obtain a fuller picture of the effects of the statistical methods used on counting official language minorities in Canada. We also added the inclusive definition of Francophone (IDF) for the province of Ontario, along with the new calculation method that the Canadian government will be using, starting with the 2021 Census, to target regions that have an “significant demand” for services in the minority language. The goal is to contribute to dialog on the statistical methods to define official language minorities used in large-scale surveys, well as those used to plan government services and by organizations working in minority settings.
