Sub-sub-series consists of maps created or maintained by Statistics Canada for work related to the 1971 census. Sub-sub-series consists of maps in three formats.
First, the sub-sub-series consists of a set of microfilmed maps that Statistics Canada made available for purchase in the 1970s; for details, consult the linked lower-level file "Microfilm set for the 1971 census maps."
Second, the sub-sub-series consists of a wide range of manuscript and printed maps, including originals and printed copies, but these have not yet been processed; description of available manuscript and printed maps is available in linked accession records. Accession RG31M 79003/23 (MIKAN 189710) includes tens of thousands of maps identified by electoral district and enumeration area number, as well as an estimated 3200 compilation sheets identified by district and enumeration area number. Accession with BAN 2007-00352-X (RCN 2007-0456) includes an estimated 3300 census reference maps that were likely scanned and are now available as .tiff files (see below). Reference maps in that accession (BAN 2007-00352) are of types: G13 (large urban, census tract); G14 (small urban, place maps); rural (NTS); G21 (provincial census tract); unincorporated places.
Third, the sub-sub-series consists of scanned copies (in .tiff format) of core printed and manuscript maps. Statistics Canada created these scanned copies, and grouped the electronic files into the 8 map series they used to organize most 1971 census maps:
Series G71-10 is Census divisions (CDs) and Census subdivisions (CSDs) for each province. As described in the Statistics Canada Illustrated Glossary (2017), a census division (CD) is "the general term for provincially legislated areas (such as county, municipalité régionale de comté and regional district) or their equivalents. Census divisions are intermediate geographic areas between the province/territory level and the municipality (census subdivision)." It is further noted that "next to provinces and territories, census divisions are the most stable administrative geographic areas, and are therefore often used in longitudinal analysis." Census subdivision (CSD) is the general term for municipalities, as determined by provincial/territorial legislation, or areas treated as municipal equivalents for statistical purposes (e.g., Indian reserves, Indian settlements and unorganized territories). There are 54 classification types based on official designations adopted by provincial/territorial or federal authorities. A census subdivision type accompanies the census subdivision name in order to distinguish CSDs from each other.
Series G71-11 are large scale index maps of metropolitan area census tracts. Census metropolitan areas (CMAs) are one or more adjacent municipalities centred on a population centre (known as the core) with a total population of at least 100,000 of which 50,000 or more must live in the core. Census tracts (CTs) are small, relatively stable geographic areas that usually have a population between 2,500 and 8,000 persons, located in census metropolitan areas and in census agglomerations that had a core population of 50,000 or more in the previous census.
Series G71-12 is rural Enumeration areas (EAs).
Series G71-13 is Census tract (CT)/Enumeration areas. Series G71-14 is Small enumeration areas.
The G71-21 map series covers the boundaries of all Provincial census tracts (PCTs) and Census metropolitan areas. Additionally, Census agglomerations (CAs) containing census tracts are also identified; a Census agglomeration is one or more adjacent municipalities centred on a population centre (core) of at least 10,000.
The series G71-Unincoporated Places covers clusters of five or more occupied dwellings in rural areas, locally known by a specific name but not having a local government or legal limits. This map series was discontinued after the 1991 Census.
The series G71-Reference maps shows the location of the geographic areas for which census data are tabulated and disseminated. The maps display the boundaries, names and codes of standard geographic areas, as well as major cultural and physical features, such as roads, railroads, coastlines, rivers and lakes.
For details on the scanned maps available for each 1971 Census map series, consult the relevant linked lower-level file description.
Sub-sub-series also consists of booklets describing the enumeration area boundaries used for the 1971 census. There is one booklet per electoral district. The booklets also feature the number of farms, number of households, and the population that existed, in 1966, in each 1971 enumeration area. See relevant linked lower-level file description for details. Finally, sub-sub-series consists of compilation sheets used for the 1971 Census of Canada; these compilation sheets, dated 1972, can be ordered as RG31M 79003/23 boxes 65-66.
