The code is assigned from east to west. The first digit represents the region of Canada to which the province/territory belongs; the second digit denotes one of the ten provinces and two territories. Region Province Code Code Atlantic Newfoundland 10 Prince Edward Island 11 Nova Scotia 12 New Brunswick 13 Quebec Quebec 24 Ontario Ontario 35 Prairies Manitoba 46 Saskatchewan 47 Alberta 48 B.C. British Columbia 59 Territories Yukon Territory 60 Northwest Territories 61 The 2-digit province/territory code is a unique identifier that must be used when identifying a specific area within the hierarchy (i.e., FED, EA, CD, CCS, CSD and SPR). Field 2: Federal Electoral District (FED) Code (1987 Representation Order) The FED is designated by a 3-digit code. In order to uniquely identify each FED in Canada, the code must be preceded by the 2-digit province code. For example: PR/FED Code FED Name 12 005 Central Nova 47 005 Regina-Lumsden 59 001 Burnaby-Kingsway 61 001 Nunatsiaq 1Field 3: Enumeration Area (EA) Code The EA is designated by a 3-digit code. In order to uniquely identify each EA in Canada, the code must be preceded by the 2-digit province code and the 3-digit FED code. For example: PR/FED/EA Code Description 12 009 251 Province 12: Nova Scotia FED 009: Halifax West EA: 251 35 009 251 Province 35: Ontario FED 009: Cambridge EA: 251 46 009 251 Province 46: Manitoba FED 009: Winnipeg North EA: 251 Field 4: Census Division (CD) Code The CD is designated by a 2-digit code based on the Standard Geographical Classification (SGC). In order to uniquely identifiy each CD in Canada, the code must be preceded by the 2-digit province code. For example: PR/CD Code CD Name 12 03 Digby County 24 03 La Cote-de-Gaspe 35 15 Peterborough County 59 15 Greater Vancouver Regional District Field 5: Census Subdivision (CSD) Code The CSD is designated by a 3-digit code based on the Standard Geographical Classification (SGC). In order to uniquely identify each CSD in Canada, the code must be preceded by the 2-digit province code and the 2-digit CD code. For example: PR/CD/CSD Code CSD Name 12 09 021 Halifax 35 09 021 Perth Field 6: 1991 CSD Population This field provides the 1991 population of the CSD in which the EA is located. 1Field 7: 1991 CSD Net Land Area The 1991 CSD net land area refers to land area in square kilometres and excludes discernable bodies of water found on maps used to calculate land area. Field 8: Census Consolidated Subdivision (CCS) Code The code assigned to each CCS is based on the Standard Geographical Classification (SGC) code of one of its component CSDs, usually the one with the largest land area. Field 9: Census Metropolitan Area (CMA)/Census Agglomeration (CA) Code The CMA/CA is designated by a 3-digit code that uniquely identifies each urban centre in Canada. The first digit of the CMA/CA code uses the second digit of the province code (except for the Territories where the CMA/CA code starts with number 9). If a CMA or CA crosses a provincial boundary, the first digit of the code reflects the province that contains the CMA portion with the higher population (e.g., CMA code 505 for Ottawa-Hull). The second and third digits are assigned in numeric order from 1 to 99 by province. For example: CMA/CA Code CMA/CA Name Province 001 St. John's 10 205 Halifax 12 421 Quebec 24 505 Ottawa-Hull 35 935 Victoria 59 990 Whitehorse 60 995 Yellowknife 61 NOTE: The CMA/CA code will read as "000" in cases where the EA is not inside the boundaries of the CMA/CA. Field 10: CMA/CA Type This field identifies the type of CMA or CA in which the EA is located. For example: Code CMA/CA Type A Consolidated CMA B Regular CMA C Consolidated CA D Regular CA NOTE: This field will be left blank in cases where the EA is not inside the boundaries of CMAs/CAs. In some parts of Canada, adjacent CMAs and/or CAs are socially and economically interrelated. When this occurs, they are grouped into a single consolidated CMA. A regular CMA, on the other hand, is free-standing. It is either not adjacent to or not sufficiently related to another CMA or CA to be consolidated. Also, adjacent CAs may be socially and economically interrelated. When this occurs, they are grouped into a single consolidated CA. A regular CA, on the other hand, is free-standing. It is either not adjacent to or not sufficiently related to another CMA or CA to be consolidated. Field 11: Primary Census Metropolitan Area/Primary Census Agglomeration (PCMA/PCA) Code The PCMA/PCA is designated by a 3-digit code that uniquely identifies each PCMA/PCA in Canada. The first digit of the PCMA/PCA code uses the second digit of the province code. If a PCMA or PCA crosses a provincial boundary, the first digit of the code reflects the province that contains the PCMA portion with the higher population (e.g., PCMA code 505 for Ottawa-Hull). The second and third digits are assigned in numeric order from 1 to 99 by province. PCMA/PCA Code PCMA/PCA Name PROV 225 Sydney 12 531 Newcastle 35 837 Spruce Grove 48 NOTE: The PCMA/PCA code field will read as "000" in cases where the EA is not inside the boundaries of a PCMA/PCA. Field 12: PCMA/PCA Type This field identifies the type of PCMA or PCA in which the EA is located. For example: Code Type A PCMA C PCA NOTE: This field will be left blank in cases where the EA is not inside the boundaries of a PCMA/PCA. Field 13: Urban/Rural Status Code This code indicates the urban/rural status of EAs inside and outside CMAs/CAs. For example: 1 Urbanized core - EAs inside CMA/CA 2 Urban fringe - EAs inside CMA/CA 3 Rural fringe - EAs inside CMA/CA 4 Urban area - EAs outside CMAs/CAs 5 Rural area - EAs outside CMAs/CAs The urbanized core, urban fringe and rural fringe are traditionally referred to as "CMA/CA parts". Field 14: CMA/CA Population This field provides the 1991 population of the CMA or CA in which the EA is located. 1Field 15: Census Tract (CT)/Provincial Census Tract (PCT) Code The CT/PCT is designated by a unique 4-digit code. CT codes are 4-digit numbers less than 7000; provincial census tract codes are 4-digit numbers greater than or equal to 7000. CT PCT 0001-6999 7000-9999 Field 16: CT/PCT Name The CT name is a unique 7-digit number (including leading blanks [b] and the decimal point), assigned in ascending order within a CMA or CA. However, CT names may not be unique between CMAs or CAs. The PCT name is also a 7-digit number (with no leading blanks and including the decimal point), assigned in ascending order within a province. If a CT or a PCT is split into two or more parts due to a population increase, the numbers after the decimal point identify the splits. For example: CT Name Code CT Name in 1986 CT Name in 1991 b400.00 b400.01 b400.02 PCT Name Code PCT Name in 1986 PCT Name in 1991 1000.00 1000.01 1000.02 Field 17: Subprovincial Region Code (SPR) The SPR is designated by a 2-digit code. In order to uniquely identify each EA in Canada, the code must be preceded by the 2-digit province code. For example: PROV/SPR SPR Name 10 10 Avalon Peninsula 35 10 Eastern Ontario 46 30 Southwestern Manitoba 48 30 Calgary 1Field 18: Urban/Rural Area Code This field provides the identification of the urban area, or indicates that the EA is in a rural area. Urban Area (UA) Code The UA is designated by a 4-digit code which uniquely identifies each UA in Canada, ranging from "0001" to "9999". There are 5 urban areas which cross provincial boundaries. Urban Area Name Urban Area Code Province Codes Campbellton 0122 13 and 24 Hawkesbury 0365 24 and 35 Ottawa-Hull 0616 24 and 35 Flin-Flon 0282 46 and 47 Lloydminster 0478 47 and 48 Rural Area Code Rural areas are indicated by "0000". Field 19: Urban Area Population This field identifies the 1991 Census population of the urban area. Field 20: 1991 EA Population This field provides the 1991 Census population of the EA. Field 21: EA Occupied Dwelling Counts This field provides the total number of occupied private dwellings in each EA. Field 22: Incompletely Enumerated Indian Reserve or Indian Settlement Flag This field designates those EAs located in incompletely enumerated Indian reserves and Indian settlements. On some Indian reserves and Indian settlements in the 1991 Census, enumeration was either not permitted or was interrupted before it could be completed. The EAs represented by this field are identified by a "1"; however, the field is left blank in cases where the EAs it represents are not part of incompletely enumerated Indian reserves or Indian settlements. 1Field 23: UTM zone number of EA representative point This field denotes the UTM zone in which the EA representative point is located. This field should be used in conjunction with the x and y coordinate values of the EA representative point (ZXY = ZONE + XCOOR + YCOOR). Region Province Code UTM Zone (s) Atlantic Newfoundland 10 19,20,21,22 Prince Edward Island 11 20 Nova Scotia 12 19,20,21 New Brunswick 13 19,20 Quebec Quebec 24 17,18,19,20,21 Ontario Ontario 35 15,16,17,18 Prairies Manitoba 46 14,15 Saskatchewan 47 12,13,14 Alberta 48 11,12 B.C. British Columbia 59 7,8,9,10,11 Territories Yukon Territory 60 7,8,9,10 Northwest Territories 61 8,9,10,11,12,13, 14,15,16,17,18, 19,20,21 Sixteen UTM zones cover Canada, bearing numbers 7 to 22 from west to east. Field 24: UTM x-coordinate (easting) of EA representative point The UTM x-coordinate or easting of the EA representive point is a 6-digit value in metres. Eastings are measured from the central meridian (called the 500,000 metre line) for each zone. The points west of the central meridian have easting values of less than 500,000; points east of the central meridian have values greater than 500,000. Eastings are all greater than 0 and less than 1,000,000. Field 25: UTM y-coordinate (northing) of EA representative point The UTM y-coordinate or northing of the EA representative point is a 7-digit value in metres. Northings are measured by their distance in metres from the equator. Because Canada's southernmost point is about 4,620,000 metres from the equator, all points in Canada have a northing value greater than 4,620,000. 1Field 26: Latitude of EA representative point This field identifies the latitude (in degrees and decimals north of the equator) of the EA representative point. Latitude is the angle, measured north or south from the equator, that identifies a particular parallel. It ranges from 0o at the equator to 90o at the poles, and requires the letter N or S to establish its position north or south of the equator. Field 27: Longitude of EA representative point This field represents the longitude (in degrees and decimals west of the prime meridian) of the EA representative point. Longitude is the angle that identifies a meridian. Measured east or west as indicated by the letter E or W, it ranges from 0o at the prime meridian (anchored by international agreement through the Royal Observatory at Greenwich, England) to 180o at the approximate location of the International Date Line. Field 28: Lambert x-coordinate (easting) of EA representative point This field identifies the x-coordinate or easting of the EA representative point in metres relative to a predefined origin so that the coordinate is positive. For Canada maps, the false easting is normally 6,200,000 metres. Field 29: Lambert y-coordinate (northing) of EA representative point This field identifies the y-coordinate or northing of the EA representative point in metres relative to a predefined origin so that the coordinate is positive. For Canada maps, the false northing is normally 3,000,000 metres. Field 30: National Topographic System (NTS) Map Number This field identifies the NTS map number in which the EA representative point is located. The NTS map numbering system is based on the partitioning of 1:1,000,000 primary quadrangles for the various NTS map series (for example, 21M represents a quadrangle for the 1:250,000 series and 21M13 represents a quadrangle for the 1:50,000 series). However, for the Geographic Attribute File, the NTS map number is based on the 1:50,000 series only. Field 31: Federal Electoral District (FED) Name This field identifies the name of the FED in which the EA is located. FED names are official names created by the Chief Electoral Officer and passed into law through an act of Parliament. Similarly, FED names can only be changed through such an act. Field 32: Census Division (CD) Name This field identifies the name of the CD in which the EA is located. 1Field 33: Census Subdivision (CSD) Name This field identifies the name of the CSD in which the EA is located. Field 34: Census Subdivision (CSD) Type The CSD type indicates the municipal status of a census subdivision. The following list indicates all CSD types and their abbreviations: Abbreviation CSD types BOR Borough C City - Cite CM County (municipality) COM Community CT Canton (municipalite de) CU Cantons unis (municipalite de) DM District municipality HAM Hamlet ID Improvement district IGD Indian government district LGD Local government district LOT Township and royalty MD Municipal district NH Northern hamlet NV Northern village P Paroisse (municipalite de) PAR Parish R Indian reserve - Reserve indienne RM Rural municipality RV Resort village SA Special area SCM Subdivision of county municipality SD Sans designation (municipalite) S-E Indian settlement - etablissement indien SET Settlement SRD Subdivision of regional district SUN Subdivision of unorganized SV Summer village T Town TP Township TR Terres reservees UNO Unorganized - Non organise V Ville VC Village cri VK Village naskapi VL Village VN Village nordique 1Field 35: Census Consolidated Subdivision (CCS) Name This field identifies the name of the CCS in which the EA is located. CCS names usually reflect the name of the largest (in terms of land area) CSD component. Field 36: Census Metropolitan Area (CMA)/Census Agglomeration (CA) Name Where applicable, this field identifies the name of the CMA/CA in which the EA is located. CMA/CA names are usually based on the largest urban centre(s) within the CMA/CA. Field 37: Primary Census Metropolitan Area (PCMA)/Primary Census Agglomeration Area (PCA) Name Where applicable, this field identifies the name of the PCMA/PCA in which the EA is located. PCMA/PCA names are usually based on the largest urban centre(s) within the PCMA/PCA. Field 38: Urban Area (UA) Name Where applicable, this field indicates the name of the urban area in which the EA is located. UA names are assigned according to the following rules: a) If the principal CSD within the urban area is a town, village or city and the urban area population within the CSD is at least 75% of the CSD population, then the CSD name is assigned to the urban area; b) If the urban area population is less than 75% of the CSD population, or if the principal CSD is not a city, town or village, then an appropriate place name is assigned to the urban area; and c) A compound name is assigned to the urban area if it contains two or more census subdivisions.
