I think you’re asking me if we can trust the statistics that were collected in the last census to determine our demographic weight. The question is whether the right questions were asked. That’s the first thing. Very often, a few much more specific questions should be added for official-language minorities.
Often the problem that we see when we look at the statistical data is that it doesn't necessarily reflect the entire demographic reality with respect to the changes that occur in an official-language minority community. On the one hand, the population does a lot of moving and shifting and, on the other, we see that there is a lot of exogamy. This means that the answer will often change depending on how it is expressed in a survey.
A few questions should be reviewed in order to obtain more specific information about the relationship between immigration, the demographic weight and the use of the language in the community once someone has integrated into Canadian society.
