Sub-sub-series consists of maps created or maintained by Statistics Canada for work related to the 1976 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 7368 printed and reference maps remain unprocessed at the accession level. The estimated 2368 reference maps in one accession (with BAN 2007-00352) are of types: G10 (census division/census sub-division, by province); G12 (rural, NTS); G13 (large urban, census tract); G14 (small urban, place maps); G18 (FED/EA); G21 (provincial census tract). The estimated 5000 maps in another accession (RG31M 82303/33) are organized by Electoral District, and list the varied base maps that Statistics Canada annotated for its work related to the 1976 census.
Second, the sub-sub-series consists of scanned copies (in .tiff format) of core printed and manuscript maps for the 1976 census maps. Statistics Canada created these scanned copies, and grouped the electronic files into the 7 map series they used to organize most 1976 census maps:
The 1976 Census maps are divided into 7 series:
Series G76-10 map series covers the Census divisions (CD) and Census subdivisions (CSD) 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 G76-12 covers rural Enumeration aeas (EAs).
Series G76-13 covers Census tracts/Enumeration areas (CTs/EAs). Census tracts 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 G76-14 map series covers small Enumeration areas.
Series G76-18 map series covers 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.
Series G76-21 show the boundaries of all Provincial census tracts (PCTs), and Census metropolitan areas (CMAs). Census metropolitan areas 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. 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 of reference maps shows the location of the geographic areas for which census data are tabulated and disseminated.
