That depends on the survey we are dealing with.
In the case of the survey on the vitality of official-language minorities, since it used a sample, it was possible to make estimates over quite a wide geographical area, but perhaps not on such a specific geographical scale as the census provided; that allowed us to find out what the situation was in the municipalities and in the school boards.
By contrast, the elementary-secondary education survey is a complete tally of all children in all provinces and territories, down to the level of each school board. It counted all children and teenagers registered in a school.
There is a major difference between a survey conducted using samples and a survey that collects extensive administrative data from each province and territory.
