It's definitely incomplete, particularly when we are welcoming immigrants whose mother tongue is not French and not the main language they use at home.
I believe that other indicators are important. One would be the language of education for children, which will help French penetrate into private space. We need to acknowledge that to obtain a more subtle and complete picture, we need more than language spoken most often at home. It could be the use of a secondary language, but to what extent is there a link between that and the language of work, and between that and the language of education?
And we shouldn't hide the fact that things are not doing so well outside Quebec. That's fairly clear, just because the issues pertaining to the transmission or non-transmission of the language are nevertheless important.
So I wouldn't say that we're outdated. I would simply say that we need something more substantial and more nuanced in terms of information.
