One obvious area is the language used in cultural activities.
A survey was conducted by the Office québécois de la langue française some years ago. In addition to censuses, one mustn't forget surveys. For information about language used in public areas, we need to look at surveys.
This cultural activity survey clearly identified major problems. This was only to be expected. One example is the language used by businesses in dealing with the public, which has been problematic according to the surveys. The situation improved significantly until around 2001, but it has worsened ever since.
There are all kinds of other areas, but we don't have enough time to discuss them.
