17 Data Quality 4.1.11. Comment This field contains address information for selected enumeration areas (EAs). An EA may be a single apartment building, large townhouse complex, hospital, jail or a Canadian Armed Forces ship. This information includes the name of the building or complex (if available) and address. Most of these EAs have a single address, although some may have an address range. Users should be aware that the source of this information is the census representatives, taken at the time of census collection. This information was then standardised during the production of the enumeration area reference maps for census tracts. The information may or may not reflect the current name or address of the building or complex. It is difficult to determine the data quality of this information. 4.1.12. Street Network Flag This flag designates census subdivisions (CSDs) that are covered by a Street Network File (SNF). In the GeoRef tables, a CSDsnf value of ‘1’ indicates that a CSD is covered by a SNF. If the field contains a zero, the CSD is not covered by a SNF. 4.1.13. EA Reference Map Lists The EA Reference Map Lists were compiled during the production of the enumeration area reference maps for the 1996 Census. The lists were then provided for input to GeoRef. 4.1.14. Reports The reports in GeoRef are derived based on the data extracted from the Query - Geographic Attribute Data Base. 4.1.15. Secondary Province Code The secondary province (XPR) field in Chart Search is used to indicate which census metropolitan areas/census agglomerations (CMA/CA), primary census metropolitan areas/primary census agglomerations (PCMA/PCA) and urban areas (UA) cross provincial boundaries. XPR is read in conjunction with the PR (code) field to obtain the names of these provinces. For example, the urban area of Flin Flon crosses Manitoba and Saskatchewan. The PR code shows the code for Manitoba and the XPR code shows the code for Saskatchewan. In Name Search and Code Search, the other province is indicated as ‘XProv’. This field is derived based on data in the Query - Geographic Attribute Data Base. 4.1.16. Enumeration Area Correspondence The Enumeration Area Correspondence (EACorr) file describes the relationship of the 1991 enumeration area (EA) with the 1996 EA. The fields available through choosing EACorr are the enumeration area unique identifier (EAuid), the previous census enumeration area unique identifier (PC_EAuid) and the previous census part flag (EApart91). The EApart91 indicates that the 1991 EA is partially contained within the 1996 EA boundary. Together, these fields allow comparison between the 1991 and 1996 enumeration areas. This EApart91 is ‘0’ if the 1991 EA corresponds to only one 1996 EA and ‘1’ if it corresponds to more than one 1996 EA. Statistics Canada – Cat. No. 92F0085XCB GeoRef
