This document is primarily intended as a reference tool on the different sources of language information available to users of Statistics Canada data. It lists, in addition to the census, the surveys and administrative databases that provide information on official languages. The information provided in this document will facilitate access to Statistics Canada data by informing researchers about the availability of survey data, access to databases and, especially, the various themes that can be explored to contribute to what is known about official-language minorities in Canada.
The document begins by providing general information about access to Statistics Canada data. We then present the language concepts measured by the various surveys and the related questions asked in each one. This is followed by summaries of the flagship surveys, or those surveys which, because of their sample size, subject or the range of language questions, are considered the most important sources of data on official-language minorities.
