I understand your question perfectly.
All the data on the socio-economic characteristics or the economic development of the communities no longer come from the census, but from the national household survey. Having a provincial or regional perspective is not a major challenge. The information is good and, in my opinion, it is possible to come to solid conclusions with information from that data base.
The challenge lies elsewhere, with very small communities. Obviously, most of the francophones in minority communities are part of the overall picture of the province. However, if you are interested in a municipality, for example, in which there is a small number of francophones, it is very hard and even impossible to draw a conclusion or analyze their situation, including because of the lack of responses from these small municipalities. There are roughly 50,000 francophones in minority communities for whom we have no specific information about their communities. Statistics Canada was unable to provide information on their communities because the rate of response was far too low.
