Census geographic units of Canada?qsrc=3044

Outline map of Canada's census divisions in 2001.

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

Census divisions consist of groups of municipalities such cities, counties, municipal districts and rural municipalities. Each census division is numbered.
British ColumbiaCensus divisions correspond with regional districts or municipalities.
New Brunswick

Census divisions correspond with counties.
Newfoundland and LabradorCensus divisions are delineated without reference to administrative or other forms of division and are numbered.[2]
Northwest TerritoriesCensus divisions do not correspond with the administrative regions of the Northwest Territories.
NunavutCensus divisions correspond with the administrative regions of Nunavut.
OntarioCensus divisions consist of "upper-tier" municipalities (counties, districts, regional municipalities, cities).
QuebecCensus divisions mostly correspond to regional county municipalities or equivalent territories.
YukonA 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 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 subdivisions

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

Dissemination areas

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" and 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. They do not, however, cross the Canada–United States border.

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.[verification needed]

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.

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.

Urban areas

An "urban area" (UA) is any grouping of contiguous dissemination areas that has a minimum population of 1,000 and average population density of greater than 400 persons per square kilometre.
