Hierarchy - Standard Geographic Units 2013-12-02 Statistique Canada • Statistics Canada 3 Module 1 – Administrative Areas Administrative areas (7)  Defined by federal, provincial or territorial statutes  Adopted for the purposes of the census  Some exceptions 2013-12-02 Statistique Canada • Statistics Canada 4 2

1.1 Provinces / Territories 2013-12-02 Statistique Canada • Statistics Canada 5 Module 1 – Administrative Areas 1.2 Census Divisions  Census divisions (CDs): o provincially legislated areas (county, municipalité régionale de comté and regional district) or their equivalents o No legislation in MB, SK or AB to create CDs. SC creates CDs in cooperation with these provinces o Intermediate geographic areas between province level and the municipality  CD code • two-digit code based on the Standard Geographical Classification (SGC). • always preceded by the two-digit province/territory (PR) code: • How many CDs in Quebec? 6 3

Module 1 – Administrative Areas 1.2 Census Divisions (cont’d)  Where can I find changes to CDs ?  Where can I find a list of CD types?  Map of CDs 7 Module 1 – Administrative Areas 1.3 Census subdivision CSD  Census subdivision (CSD): • municipalities as determined by provincial/territorial legislation • areas treated as municipal equivalents for statistical purposes (e.g. Indian reserves, Indian settlements and unorganized territories) • 54 types of CSDs; usually indicated after the CSD name  CSD code: • three-digit code based on the Standard Geographical Classification • always preceded by the two-digit PR code and the two-digit CD. 8 4

Module 1 – Administrative Areas 1.4 Federal electoral district (FED)  Federal electoral district (FED): • area represented by a member of the House of Commons • boundaries based on the 2003 Representation Order (308 FEDs)  FED code: • three-digit code preceded by the two-digit PR code.  Map 9 Module 1 – Administrative Areas 1.5 Designated Place (DPL)  DPL: • a small community or settlement that does not meet the CSD or population centre criteria • created by SC in cooperation with provinces and territories • Criteria: area <= 10 sq km; pop. > 1,000 & pop. density < 400 per sq km • Provide data for submunicipal areas  DPL code: • a four-digit code preceded by the two-digit PR code. 10 5

1.5 Designated Place DPL cont’d  Types of DPL  Changes to DPL  Number of DPL 11 Module 1 – Administrative Areas 1.6 Postal Code (PC) & Forward Sortation Area (FSA)  PC: • six-character code for the purpose of sorting and delivering mail • defined and maintained by Canada Post Corp. • collected from the census questionnaire • not necessarily a match of the boundaries of standard geographic areas; one PC could sit on two or more CSD  FSA: • identified by the first 3 characters of the postal code • associated with a postal facility 12 6

13 Module 2 – Statistical Areas  defined by Statistics Canada, in cooperation with provinces and territories for the purpose of disseminating census data  Some areas complement the structure of administrative regions (ER, CAR & CCS) 14 7

Module 2 – Statistical Areas 2.1 Economic Regions (ER) Economic region (ER):  a grouping of complete census divisions (CDs) - one exception in Ontario  created for analysis of regional economic activity  created by agreement between SC and provinces (Quebec’s ERs designated by law; called “régions administratives” ER code:  A two-digit code preceded by the two-digit PR code:  changes to ERs  maps of ERs 15 2.2 Census agricultural region (CAR) Census agricultural region:  groups of adjacent census divisions  In SK, groups of adjacent census consolidated subdivisions  Prairie provinces CARs are commonly referred to as crop districts CAR code  a two-digit code precede by the PR code 16 8

2.3 Census consolidated subdivisions (CCS) CCS  group of adjacent CSDs  created for disseminating census of agriculture data.  In SK, CCS are the building blocks for CARs; CCS code  7 digit SGC code of one of its component CSDs with the largest land area. 17 2.4 Population centre (POPCTR) & Rural area POPCTR  In 2011, POPCTR replaces the term 'urban area' (UA)  area with a pop. of at least 1,000 and no fewer than 400 per sq. km  classified into three groups • small POPCTR: population between 1,000 and 29,999 • medium POPCTR: population between 30,000 and 99,999 • large urban POPCTR: population of 100,000 or more Rural area  All areas outside POPCTRs are classified as rural areas 18 9

2.4 Population centre (POPCTR) and Rural area POPCTR code  four-digit codes assigned sequentially; preceded by the PR code. 19 Module 2 – Statistical Areas 2.5 Census Metropolitan area (CMA) & Census Agglomeration (CA) CMA  Consist of one or more adjacent CSDs • centered on a population centre (known as the core) • Core area has a minimum population of 50,000 • CMA minimun population of 100,000 • Adjacent CSDs must have a high degree of integration with the core • All subdivided into Census tracts (CTs)  CMA status remains even if • population of core declines under 50k • population of CMA declines under 100k 20 10

Module 2 – Statistical Areas 2.5 CMA & CA cont’d Census agglomeration (CA) • must have a core population of at least 10,000 • Adjacent CSDs must have a high degree of integration with the core CA looses its status or is retired • If population of core declines under 10,000 CA gains Census tracts • If population of core increases over 50,000 • CTs remains even if population of core decreases 2013-12-02 Statistique Canada • Statistics Canada 21 Module 2 – Statistical Areas 2.5 CMA & CA cont’d  CMA / Ca code • unique three-digit code  First digit corresponds to the second digit of the province code 2013-12-02 Statistique Canada • Statistics Canada 22 11

Module 2 – Statistical Areas 2.5 CMA & CA cont’d CMA/CA changes for 2011 Census • Where can I find changes (names and new CA) CMA/CA number CMA/CA MAPS 2013-12-02 Statistique Canada • Statistics Canada 23 2.6 Census Tracts (CTs) CTs  are located in CMAs & CAs that have a core population >= 50,000 • All 33 CMA are divided in CTs • 15 out of 144 CAs divided in CTs  Most important geographic areas needed for urban, health, social, education and market planning & research 24 12

2.6 Census Tracts (CTs) cont’d CTs delineating rules: • Permanent, easily recognizable physical features • Population between 2,500 and 8,000 (average of 4,000) • Homogeneous in terms of socioeconomic characteristics  similar economic status and social living conditions • Shape should be as compact as possible • Respect CMA, CA & PR boundaries but do not necessarily respect CSDs boundaries. 25 2.6 Census Tracts (CTs) cont’d CTs naming & coding  Each CT has a seven-character numeric 'name' • (including leading zeros, the decimal point and trailing zeros).  To identify each CT in its CMA or amongst the 15 CAs, the three-digit CMA/CA code must precede the CT 'name'. For example: 26 13

2.6 Census Tracts (CTs) cont’d CT splits  When a CT is split into two or more parts due to a population increase, the number after the decimal point identifies the splits. • CT 0042.00 becomes CT 0042.01 and CT 0042.02  Census Tract Reference Maps, by Census Metropolitan Areas or Census Agglomerations 27 2.7 Dissemination block (DB)  area bounded on all sides by roads and/or boundaries of standard geographic areas  Only population and dwelling counts are disseminated  DBs with pop. < 15 are adjusted 28 14

2.7 Dissemination block (DB) contd DB coding Each DB is assigned a two-digit code preceded by the two-digit province/territory (PR) code, the two-digit census division (CD) code and the four-digit dissemination area (DA). For example: 29 2.8 Dissemination Area (DA) DA  small, relatively stable geographic unit • composed of one or more adjacent dissemination blocks (DBs)  smallest standard geographic area for which all census data are disseminated • Population size 400 to 700 persons 30 15

2.8 Dissemination Area (DA) contd DA boundaries  respect the boundaries of CSDs & CTs  follow roads mostly; may follow railways, water features, power transmission lines DA coding  A four-digit code preceded by the two-digit (PR) code and the two-digit (CD) code. 31 2.8 Dissemination Area (DA) cont’d Changes • In 2001  DA replaced the enumeration area (EA)  All EAs (in CMAs and CAs with CTs) were adjusted to created DAs  In rural areas, DAs = EAs • In 2006  DAs were delineated outside CTs (rural areas)  Some changes in DAs occured with boundary changes in CMAs / CAs / CTs 32 16

Statistical area classification (SAC) Purpose • Groups all CSDs as components of a CMA, a CA or a Census Metropolitan Influenced Zone (MIZ) Statistical area classification (SAC) 2013-12-02 Statistique Canada • Statistics Canada 34 17
