Sub-sub-series consists of maps created or maintained by Statistics Canada for work related to the 1981 census. Sub-sub-series consists of maps in two formats.
First, the sub-sub-series consists of a range of manuscript and printed maps. Approximately 4000 compilation maps, arranged by federal electoral district, can be ordered by citing the electoral district number used by Statistics Canada. An estimated 2765 census reference maps for the 1981 census remain unprocessed (BAN 2007-00352-X - RCN 2007-0457), and are of types: G12 rural (NTS); G13 (large urban, census tract); G14 (small urban, place maps); G18 (FED/EA maps); G21 (provincial census tract). Those approximately 2765 census reference maps in BAN 2007-00352-X, however, were likely scanned and are now available as .tiff files (see below).
Second, 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 used to organize most 1981 census maps:
The G81-10 map series covers the Census divisions (CD) and Census subdivision (CSDs) for each province. As described in the Statistics Canada Illustrated Glossary (2017), a census division 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 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.
The G81-12 map series shows the boundaries of Enumeration areas (EAs) in the rural areas of Canada. This series also shows the boundaries of Census divisions, Census subdivisions and Federal electoral districts (FEDs); a FED is an area represented by a member of the House of Commons, established based on population counts from each decennial census as determined by the Chief Electoral Officer of Canada and electoral boundaries commissions. The boundaries, name, and population of each FED are included in a representation order (RO); names of FEDs may change at any time through an Act of Parliament.
Each map in the G81-13 series covers one or more Census tracts (CTs), which are small, relatively stable geographic areas that usually have a population between 2,500 and 8,000 persons, 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.
The maps in the G81-14 map series show the Enumeration areas (EAs) located in smaller urban Census subdivisions of Canada.
The G81-18 map series cover Federal electoral districts, one for each map.
The G81-21 map series shows the boundaries of all Provincial census tracts (PCTs), Census metropolitan areas (CMAs) and Census agglomerations (CAs).
The G81-CCD map series shows Consolidated census division (CCD) boundaries by Electoral district (ED).
The maps in the G81-Reference series shows the location of the geographic areas for which census data are tabulated and disseminated, displaying 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.
