    The census geographic units of Canada are the country subdivisions defined and used by Canada's federal government statistics bureau Statistics Canada to conduct the country's five-yearly census. They exist on four levels: the top-level (first-level) divisions are Canada's provinces and territories; these are divided into second-level census divisions, which in turn are divided into third-level census subdivisions (roughly corresponding to municipalities) and fourth-level dissemination areas.

    Census divisions

    Canada's second-level geographic units are called "census divisions". In terms of size, they generally lie between the top-level administrative divisions of the province and territory and third-level administrative divisions such as sections, townships and ranges. Census divisions are divided into census subdivisions (see section below).

    Census subdivisions
    Census subdivisions generally correspond to the municipalities of Canada. They include unorganized territories and the Indian reserves and settlements determined by Indian and Northern Affairs Canada.

    Census metropolitan areas
    See template below for links to census metropolitan areas by size.

    A "census metropolitan area" (CMA) is a grouping of census subdivisions comprising a large urban area (the "urban core") and those surrounding "urban fringes" and "rural fringes" with which it is closely integrated. To become a CMA, an area must register an urban core population of at least 100,000 at the previous census. CMA status is retained even if this core population later drops below 100,000.

    CMAs may cross census division and provincial boundaries.

    Consolidation
    A CMA may be consolidated with adjacent census agglomerations (CAs; see below) if they are closely integrated, to produce a grouping known as a "consolidated census metropolitan area" (CCMA). The component CMA and CAs are then described as the "primary census metropolitan area" (PCMA) and "primary census agglomeration (or agglomerations)" (PCA or PCAs).

    CMAs may not be consolidated with each other.

    Census agglomerations

    A "census agglomeration" (CA) is a smaller version of a CMA in which the urban core population at the previous census was greater than 10,000 but less than 100,000.

    top

    Census tracts
    CMAs and CAs with a population greater than 50,000 are subdivided into census tracts which have populations ranging from 2,000 to 8,000.
