### Statistical Areas
|
||||
|
||||
* **[Aggregate Dissemination Area (ADA)](https://www150.statcan.gc.ca/n1/pub/92-195-x/2021001/geo/ada/ada-eng.htm):** A dissemination geography created by grouping existing dissemination areas, census subdivisions, or census tracts to achieve a target population.
|
||||
* **[Census Metropolitan Area (CMA)](https://www150.statcan.gc.ca/n1/pub/92-195-x/2021001/geo/cma-rmr/cma-rmr-eng.htm):** An area consisting of one or more adjacent municipalities situated around a major urban core with a total population of at least 100,000.
|
||||
* **[Census Agglomeration (CA)](https://www150.statcan.gc.ca/n1/pub/92-195-x/2021001/geo/cma-rmr/cma-rmr-eng.htm):** Similar to a CMA, but with a core population of at least 10,000.
|
||||
* **[Census Tract (CT)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo013):** Small, relatively stable geographic areas within CMAs and CAs that usually have a population between 2,500 and 8,000.
|
||||
* **[Dissemination Area (DA)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo021):** A small, stable geographic unit composed of one or more adjacent dissemination blocks.
|
||||
* **[Dissemination Block (DB)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo022):** An area bounded on all sides by roads and/or boundaries of standard geographic areas; the smallest unit of census geography.
|
||||
* **[Economic Region (ER)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm%3FID%3Dgeo023):** A grouping of complete census divisions created as a standard geographic unit for analysis of regional economic activity.
|
||||
* **[Population Centre (POPCTR)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo049a):** An area with a population of at least 1,000 and a density of 400 or more people per square kilometer.
|
||||
* **[Aggregate Dissemination Area (ADA)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo053):** An aggregate dissemination area (ADA) is a dissemination geography created for the Census. ADAs cover the entire country and, where possible, have a population between 5,000 and 15,000 based on the previous census population counts. ADAs are created by grouping existing dissemination geographic areas, including census tracts (CTs), census subdivisions (CSDs) or dissemination areas (DAs). ADA boundaries respect provincial, territorial, census division (CD), census metropolitan area (CMA) and census agglomeration (CA) boundaries.
|
||||
* **[Census Metropolitan Area (CMA)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo009):** A census metropolitan area (CMA) or a census agglomeration (CA) is formed by one or more adjacent municipalities centred on a population centre (known as the core). A CMA must have a total population of at least 100,000 based on data from the current Census of Population Program, of which 50,000 or more must live in the core based on adjusted data from the previous Census of Population Program. To be included in the CMA or CA, other adjacent municipalities must have a high degree of integration with the core, as measured by commuting flows derived from data on place of work from the previous Census Program.

* **[Census Agglomeration (CA)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo009):** Similar to a CMA, but with a core population of at least 10,000. To be included in the CMA or CA, other adjacent municipalities must have a high degree of integration with the core, as measured by commuting flows derived from data on place of work from the previous Census Program.
|
||||
* **[Census Tract (CT)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo013):** Census tracts (CTs) are small, relatively stable geographic areas that usually have a population of fewer than 7,500 persons, based on data from the previous Census of Population Program. They are located in census metropolitan areas (CMAs) and in census agglomerations (CAs) that had a core population of 50,000 or more in the previous census.

* **[Dissemination Area (DA)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo021):** A dissemination area (DA) is a small, relatively stable geographic unit composed of one or more adjacent dissemination blocks with an average population of 400 to 700 persons based on data from the previous Census of Population Program. It is the smallest standard geographic area for which all census data are disseminated. DAs cover all the territory of Canada.

The dissemination block is the smallest geographic area for which population and dwelling counts are disseminated. Dissemination blocks cover all the territory of Canada.

* **[Population Centre (POPCTR)](https://www12.statcan.gc.ca/census-recensement/2021/ref/dict/az/Definition-eng.cfm?ID=geo049a):** A population centre (POPCTR) has a population of at least 1,000 and a population density of 400 persons or more per square kilometre, based on population counts from the current Census of Population. All areas outside population centres are classified as rural areas. Taken together, population centres and rural areas cover all of Canada.
|
||||
Population centres are classified into three groups, depending on the size of their population:
|
||||
* small population centres, with a population between 1,000 and 29,999
|
||||
* medium population centres, with a population between 30,000 and 99,999
|
||||
* large urban population centres, with a population of 100,000 or more.
