Thank you for your question.
We have to agree on what the expression "demolinguistic picture" means. If the goal is to paint a picture at a very specific geographic level, the census provides us with that information. It gathers data on the evolution of bilingualism, enrolments, the percentages of mother tongue populations, language use and populations for which English and French are the first official language spoken.
The first results of the National Household Survey, which were published on May 8, provided various data other than linguistic data. In addition to linguistic data, on June 26, we will be publishing data on language of work, education and level of education, industry, occupation and place of work. Of course, certain geographic challenges are involved in this, and there could potentially be some problems for small geographic regions.
