Statistical Area Classification (SAC)


The Statistical Area Classification (SAC) groups census subdivisions (CSDs) according to whether they are a component of a census metropolitan area (CMA), a census agglomeration (CA), or census metropolitan influenced zone (MIZ). The MIZ categorizes all CSDs in the provinces and territories that are outside CMAs and CAs. CSDs within the provinces that are outside CMAs and CAs are assigned to one of four categories according to the degree of influence (strong, moderate, weak or no influence) that the CMAs or CAs have on them. CSDs within the territories that are outside CAs are assigned to a separate category.
