Census Boundary Files

November 15, 2021

Question:
I have a term project which requires us to write a tutorial on free and open source geospatial software and data. My plan is to write it on how to use Python to perform areal interpolation of Canadian census data.

Up to now I’ve been using U of T's Canadian Census Analyser website to download census profile data in a format which is easy to join to the associated census boundary files but, as that website is not publicly available I will need to use data direct from StatCan. I have looked into their Beyond 20/20 formats, as well as their other methods of publishing profile data, but have not figured out any simple workflows for getting it into a format that can then be easily joined to the census boundary files.

I’ve started work on a Python function which will read in a census comprehensive file (for example) and then return a data frame that contains specific variables of interest as columns, and the census geographies as rows - basically something in the same format that the Census Analyser Website spits out. For example, all of the Ottawa-Gatineau census tracts as rows and the modes of commuting as columns.

Writing this function is not the simplest of tasks but I am getting close. I’m just wondering if I’m missing some app or resource that basically mimics the Census Analyser Website’s functionality but which is free and open source. Should I be spending more time trying to figure out how the StatCan Beyond 20/20 browser works or is there another way?

Answer:
There are the Boundary files and there are two types: cartographic and digital. Cartographic boundary files portray the geographic areas using only the major land mass of Canada and its coastal islands. Digital boundary files portray the full extent of the geographic areas, including the coastal water area. The boundary files use the Lambert conformal conic projection. Boundary files using geographic projection (latitude and longitude coordinates) are available upon request.

Also, the 2016 Census Profile is available in IVT format which needs to be read using the Beyond 20/20 Professional Browser. This software is relatively user friendly and allows users to navigate through a large dataset. A set of slides is included, which includes a tutorial on how to use the tool.

2011 Geography Poducts

Good afternoon!

I would like to bring to your attention that last week, on November 29, the  Geography Division released some 2011 Geography products:

Available today are four geographic products from the 2011 Census: Boundary Files, Road Network File, Correspondence Files and the Interim List of Changes to Municipal Boundaries, Status, and Names.

These products represent the first suite of geographic products released from the 2011 Census.

Boundary Files

Question

I have what I think is a very simple question. I have a student doing an assignment – she already has population data for 2006 census and she needs the boundary files in either ArcGIS or MapInfo formats at the CT level for the CMA of St. John’s. Will the Road Network files do this or is there another product I should be providing?

Answer

I believe the RNF does not actually include the boundaries; therefore, if you go to the geography/2006/spatial-info-products/ directory/sub-directories, you'll find options for downloading both arcinfo and mapinfo format.  Depending on whether or not you want shoreline, you'll go choose cbf (with shoreline) or dbf (without shoreline).  In this case, I don't think it makes a *huge* difference if you select dbf or cbf, although I tend to default to cbf unless I have reason not to do so (which is sometimes the case).  Within each of these sub-directories are national and provincial directories.  Choose national, and you'll see a further sub-directory for CT geography.
