Release date: 2022-02-09 - Geographic files and documentation: 92-160-XDescription:
The Boundary files portray the geographic limits used for census dissemination and are available for Provinces and Territories, Census Divisions, Economic Regions, Census Metropolitan Areas and Census Agglomerations, Census Consolidated Subdivisions, Census Subdivisions and Aggregate Dissemination Area.
There are two types of boundary files: digital and cartographic. Digital files depict the full extent of the geographical areas, including the coastal water area. Cartographic files depict the geographical areas using only the major land mass of Canada and its coastal islands. The files provide a framework for mapping and spatial analysis using commercially available geographic information systems (GIS) or other mapping software.
The Boundary Files are portrayed in Lambert conformal conic projection and are based on the North American Datum of 1983 (NAD83). A reference guide is available (92-160-G).

Release date: 2020-12-11 - Surveys and statistical programs – Documentation: 89-20-00052020008Description:
This QGIS tutorial introduces the Field Calculator, used to add or update fields within the attribute table and edit features. Like the Select by Expression tool, it uses expression syntax. Follow along as we use these tools in conjunction to select and edit large selections of features. Specifically, we’ll cover syntax for adding geometric measures such as area, length and XY coordinates, as well as creating and editing feature attributes in numeric and text fields – by adding a Class field and updating the speed_rest field (speed limits) in the CPRoads layer. Build upon the foundational skills for writing expressions covered in the previous demo – using these procedures to isolate and populate feature attributes in these fields. Ensure you apply the remaining expressions and save the edits (shown at the end of the video and below) to the CPRoads layer, for use in later tutorials (Demos #10 and 23-25). Extend these skills to add, edit and update fields and feature attributes in layers relevant to your own areas of work and expertise.
Release date: 2020-02-19 - 6. Creating Vector Data ArchivedSurveys and statistical programs – Documentation: 89-20-00052020006Description:
In this QGIS tutorial you’ll learn to create a new vector layer and delineate feature geometries. Follow along as we cover the parameters, procedures and tools to delineate your own custom geometries, add fields and populate feature attributes, as well as copy and modify geometries from other layers of interest. These procedures, demonstrated with a polygon vector, equally extend to creating point and line vector geometries. Additionally, learn to enable and disable non-default (e.g. Advanced Digitizing, Shape Digitizing and Snapping) toolbars within QGIS’s interface, and enable editing tools. Apply these skills in creating layers of interest, such as custom clip layer for an area of interest (AOI), land-cover files, or training data, when equivalent datasets does not exist – enabling you to delineate geometries and populate feature attributes that suit your needs.
We’ll use the AOI layer in upcoming tutorials to standardize the extent of layers for further processing and analysis, so be sure to follow along and save your edits at the end of the demo. Stay tuned for the next tutorial, where we’ll introduce tools to select features by their attributes – enabling you to isolate features by criteria, conditions and values of interest within fields of a vector layer’s attribute table.
In this demo, we’ll delineate features with the Add Polygon Feature tool and additional tools on the Shape Digitizing toolbar. The Add Feature tool is the most common and versatile means for creating new features of any geometry type and form, while the latter tools are exclusive to polygon and line vectors - helping rapidly add regular polygon features. The Advanced Digitizing Panel is applied to snap feature segments at specified angles, while the Snapping tool facilitates aligning the vertices or segments of created features to those of other features. Similarly, copying and pasting feature geometries can also ensure alignment of created features with those of interest in other layers.
Release date: 2020-02-18 - 7. Selecting Features by Attributes in QGIS ArchivedSurveys and statistical programs – Documentation: 89-20-00052020007Description:
This QGIS tutorial covers attribute-based selection tools, which are used to query, select and subset features in a vector layer by specific criteria, conditions or values of interest within fields of the attribute table. Follow along as we work through different examples using the Select by Value and Select by Expression tools. Learn to isolate features by multiple criteria of interest, use additional selection methods (e.g. add, remove, and select features from a selection) and apply the SQL-like syntax for constructing expressions. This syntax is used in various QGIS tools. We’ll cover foundational rules, and then demonstrate creating expressions and applying associated operators to isolate text and numeric feature attributes. Learn to use wildcard characters and multiple fields in selecting features, as well as procedures for subsetting and exporting selected features to a new layer. You can then extend these skills in selecting and subsetting features by attributes in vector layers relevant to your own areas of work and expertise. We’ll continue building upon these skills in subsequent tutorials, including the next tutorial where we’ll use the Field Calculator and expression syntax to add new fields and edit feature attributes storing spatial measures, numbers and text characters.

Release date: 2019-11-13 - Articles and reports: 11-633-X2017006Description:
This paper describes a method of imputing missing postal codes in a longitudinal database. The 1991 Canadian Census Health and Environment Cohort (CanCHEC), which contains information on individuals from the 1991 Census long-form questionnaire linked with T1 tax return files for the 1984-to-2011 period, is used to illustrate and validate the method. The cohort contains up to 28 consecutive fields for postal code of residence, but because of frequent gaps in postal code history, missing postal codes must be imputed. To validate the imputation method, two experiments were devised where 5% and 10% of all postal codes from a subset with full history were randomly removed and imputed.
Release date: 2017-03-13 - 3. Geovisualization of health and social capital data derived from Statistics Canada surveys ArchivedArticles and reports: 11-522-X200600110447Description:
The classification and identification of locations where persons report to be more or less healthy or have more or less social capital, within a specific area such as a health region, is tremendously helpful for understanding place and health associations. The objective of the proposed study is to classify and map areas within the Zone 6 Health Region (Figure 1) of Nova Scotia (Halifax Regional Municipality and Annapolis Valley regions) according to health status (Dimension 1) and social capital (Dimension 2). We abstracted responses to questions about self-reported health status, mental health, and social capital from the master files of the Canadian Community Health Survey (Cycles 1.1, 1.2 and 2.1), National Population Health Survey (Cycle 5), and the General Social Survey (Cycles 13, 14, 17, and 18). Responses were geocoded using the Statistics Canada Postal Code Conversion File (PCCF+) and imported into a geographical information system (GIS) so that the postal code associated with the response will be assigned to a latitude and longitude within the Nova Scotia Zone 6 health region. Kernel density estimators and additional spatial interpolators were used to develop statistically-smoothed surfaces of the distribution of respondent values for each question. The smoothing process eliminates the possibility of revealing individual respondent location and confidential Statistics Canada sampling frame information. Using responses from similar questions across multiple surveys improves the likelihood of detecting heterogeneity among the responses within the health region area, as well as the accuracy of the smoothed map classification.

Release date: 2002-10-28 - 8. Geographic Structures As Census Variables: Using Geography to Analyse Social and Economic Processes ArchivedArticles and reports: 92F0138M2001001Description:
Traditionally, Statistics Canada uses standard geographic areas as "containers" for the dissemination of statistical data. However, geographic structures are often used as variables in general applications, for example, to document the rural and urban population in a specific area such as an incorporated municipality (census subdivision). They are not often cross-tabulated with each other to illustrate and analyse specific social and economic processes, for example, the settlement patterns of the population inside and outside of larger urban centres broken down by urban and rural areas.The introduction of the census metropolitan area and census agglomeration influenced zone (MIZ) concept presents additional opportunities to use geographic structures as variables to analyse census data.The objectives of this working paper are to illustrate the advantages of using geographic structures as variables to better analyse social and economic processes and to initiate a discussion in the user community about using these variables and the potential of this largely untapped capability of the Census databases. In order to achieve these objectives, four examples of geography as a variable are presented. The examples include Aboriginal persons living on-reserve and off-reserve in urban and rural areas in Canada, the unemployment rate of persons living in urban and rural areas in Canada, the gross rent of renter households in urban and rural areas in Canada, and the migration flows of persons 15 to 24 years of age between major urban centres and rural and small town areas (MIZ).Our intent is to encourage the use of geographic structures as census variables in order to provide users with the tools that will enable them to more accurately analyse the social and economic processes that take place in the geographic areas of Canada.

Release date: 2000-10-06 - 10. Automated Land Area Tests for the 2001 Census: Preliminary Results Using the 1996 Digital Cartographic Files ArchivedArticles and reports: 92F0138M1998001Description:
Prior to the 2001 Census, the Geography Division manually calculated land area using a planimeter. The manual approach was necessary since the division did not have a national digital database to support an automated method. The manual land area calculation was a labour intensive process as well as very time consuming, expensive and very prone to error. With the anticipation of having a national digital base for the 2001 Census (to be called the National Geographic Base or NGB), the automated land area calculation becomes a simple GIS process.
The objectives of this paper are to show the effects of data aggregation and different map projections on automated land area calculation. The testing is a two- staged process; the first stage uses the 1996 Digital Cartographic Files (DCFs) and the second stage will use the NGB. Although the DCFs are not ideal for testing land area, this two-staged approach is necessary since the NGB will not be completed until Autumn 1998. This report presents results on the first stage using the 1996 DCFs.
The results reveal that the effects of data aggregation are minimal; thus land area can be stored at the census block level and then aggregated to higher level geographic entities without any serious ramifications for the 2001 Census. The results also indicate that an equal-area projection, specifically the Albers Equal-Area Conic projection, is more appropriate for calculating land area.
