In using the Statistical Area Classification for census data tabulations, it is possible to sum census data automatically for census subdivisions (CSDs) as follows:
Care should be exercised when applying the MIZ concept in the three territories. As many CSDs in the territories are very large and sparsely populated, the place of work–population relationship upon which the MIZ is constructed is unstable.
Figure 22 shows the hierarchical relationship represented by the SAC.

Table 2 shows the population distribution of Canada from the 2001 Census using the SAC, and Table 3 shows the number of census subdivisions in each category of the SAC for the 2006 Census.
