As I understand it, you are asking whether it is appropriate to scatter what I termed “a precious resource”.
I have already clearly explained that this is not the way it is supposed to be. We could talk about this at length, but some basic indicators allow us to ascertain over time the vitality of the different linguistic groups from one census to the next. It is very important not to abandon those indicators which have served us well, which will continue to serve us well in the future and which are so valuable. They allow us to identify which people speak primarily or exclusively French at home, or English at home. If people say they speak both English and French, I adjust my analysis the same way that Statistics Canada does: I count one half as being French speakers and the other half as being English speakers. That reflects the relative frequency of their use. We are trying to get a better handle on the grey areas that normally arise when both languages are in contact with each other. Admittedly, there is bilingualism.
When we look at population growth, based on statistics from the last two censuses, we see that the number of additional French mother tongue speakers in Canada was less than 10 000 between 2001 and 2006. We have reached an historic turning point. In the next census, I am expecting to see a decline in real terms in the number of French mother tongue speakers in Canada, after simplifying the data, and taking into account double answers that may have been given.
