Standard Geographical Classification code (Canada)
The Standard Geographical Classification (SGC) is a system maintained by Statistics Canada for categorizing and enumerating the census geographic units of Canada. Each geographic area receives a unique numeric code ranging from one to seven digits, which extend telescopically to refer to increasingly small areas. This geocode is roughly analogous to the ONS coding system in use in the United Kingdom. RegionsThe SGC code format for regions is X, where X is a unique identifier incrementing from east to west, then north. 1: Atlantic Canada Provinces and TerritoriesThe SGC code format for provinces and territories is XY, where X is the above regional prefix, and Y is a further identifier incrementing from east to west. Taken as a single digit, each value of Y is unique within the province group, or unique within the territory group. 10: Newfoundland and Labrador Census divisionsThe SGC code format for census divisions is XX YY, where XX is the above province/territory code, and YY is the census division's code, unique within its own province. Census divisions are generally numbered from east to west. In some locations, a similar policy to American FIPS county codes has been adopted, with even-numbered slots being left vacant for future expansion. Examples: Census subdivisionsThe SGC code format for census subdivisions is XX YY ZZZ, where XX is the province/territory code, YY is the census division code, and ZZZ is the census subdivision's code, unique within its own census division. Census subdivisions are again generally numbered from east to west, and the practice has been to leave even-numbered slots vacant for future expansion. Examples: External links |
