Census Metropolitan Area

The census geographic units of Canada are the country subdivisions defined and used by Canada's federal government statistics bureau Statistics Canada[1] 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.

In some provinces, a census division also corresponds to a county or another similar unit of political organization, while in other provinces the boundaries are chosen arbitrarily as no such level of government exists. Two of Canada's three territories are also divided into census divisions.

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).

Nature of Canada's census divisions by province or territory
Province/Territory Nature of census divisions
Alberta
Manitoba
Saskatchewan
Census divisions consist of groups of municipalities such as cities, municipal districts, and rural municipalities. Each census division is numbered.
British Columbia Census divisions correspond with regional districts or municipalities.
New Brunswick
Nova Scotia
Prince Edward Island
Census divisions correspond with counties.
Newfoundland and Labrador Census divisions are delineated without reference to administrative or other forms of division and are numbered.[2]
Northwest Territories Census divisions do not correspond with the administrative regions of the Northwest Territories.
Nunavut Census divisions correspond with the administrative regions of Nunavut.
Ontario Census divisions consist of "upper-tier" municipalities (counties, districts, regional municipalities, single-tier cities).
Quebec Census divisions mostly correspond to regional county municipalities or equivalent territories.
Yukon A territory treated as a single census division.

In most cases, a census division corresponds to a single unit of the appropriate type listed above. However, in a few cases, Statistics Canada groups two or more units into a single statistical division:

  • In Ontario, Haldimand County and Norfolk County are grouped as a single census division, as are Brant and Brantford.
  • In Quebec, 93 of 98 census divisions correspond precisely to the territory of one regional county municipality (with the addition of Indian reserves, which do not legally belong to RCMs) or a "territory equivalent to an RCM" (which usually corresponds to a single independent city). However, there are five census divisions consisting of two or three RCMs or equivalent territories each. See List of census divisions of Quebec.

In almost all such cases, the division in question was formerly a single unit of the standard type, which was divided into multiple units by its province after the Canada 2001 Census.

Census consolidated subdivisions

A census consolidated subdivision is a geographic unit between census division and census subdivision. It is a combination of adjacent census subdivisions typically consisting of larger, more rural census subdivisions and smaller, more densely-populated census subdivisions.[3]

Census subdivisions

Census subdivisions generally correspond to the municipalities of Canada, as determined by provincial and territorial legislation.[4] They are also areas that are deemed to be equivalents to municipalities for statistical reporting purposes, such as Indian reserves, Indian settlements, and unorganized territories.[4] Statistics Canada has created census subdivisions in cooperation with the provinces of British Columbia, Newfoundland and Labrador, and Nova Scotia as equivalents for municipalities.[5] The Indian reserve and Indian settlement census subdivisions are determined according to criteria established by Indian and Northern Affairs Canada.[6]

Dissemination areas

Dissemination areas are the smallest standard geographic unit in Canada and cover the entire country.[7] As small areas, they comprise one or more dissemination blocks and have a population between 400 and 700 people.[7]

Specially-defined geographic units

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" 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, although the Ottawa-Gatineau metropolitan area in Ontario and Quebec is the only one that currently crosses a provincial border.

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. If the population of an urban core is less than 50,000, it is the starting point for the construction of a 'census agglomeration'.[8]

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.

Population centres

"Population centre" redirects here. For other uses, see Center of population.

A "population centre" (PC), formerly known as an urban area (UA), is any grouping of contiguous dissemination areas that has a minimum population of 1,000 and an average population density of 400 persons per square kilometre or greater.[9] For the 2011 census, urban area has been renamed to "population centre".[9][10] In 2011, Statistics Canada identified 942 population centres in Canada. It is important to note that some urban areas include all or parts of a number of different municipalities; that not all municipalities contain an urban area; and that some municipalities contain more than one distinct urban area. The delineation of boundaries of 'urban areas' by Statistics Canada is almost completely unrelated to the existence of municipal boundaries.[11]

The population centre level of geography is further divided into the following three groupings based on population:[9]

  • "small population centre" – 1,000 to 29,999
  • "medium population centre" – 30,000 to 99,999
  • "large urban population centre" – 100,000 and greater

Designated places

Main article: Designated place

A "designated place" (DPL) is usually a small community that does not meet the criteria used to define incorporated municipalities or urban areas (areas with a population of at least 1,000 and no fewer than 400 persons per square kilometre), but for which Statistics Canada or a provincial government has requested that similar demographic data be compiled.[12]

Localities

A "locality" (LOC) is a historical named location or place. The named location may be a former census subdivision, a former urban area, or a former designated place. It may also refer to neighbourhoods, post offices, communities and unincorporated places among other entities.[13]
