After our recent posts on multi-census comparisons I was pointed to a semi-custom tabulation for census timelines back to 1971 for Vancouver and Toronto. That’s data for the 1971, 1981, 1986, 1991, 1996, 2001, 2006 and 2011 censuses on a common 2016 DA geography for the two CMAs. This is really cool, not just that it eliminates the need to tongfen the geographies, but in particular because Statistics Canada does not even haven publicly available geographic boundary files for censuses before 2001.

What are the best metrics for understanding if a given place has enough housing, just the right amount, or too much? Whether you’re a potential renter or buyer or an analyst or policymaker, the answer really depends on what you’re looking for.
For potential renters and buyers, if you can’t find what you’re looking for and/or it’s not in your price range, then there’s not enough housing.
Canadian census data is freely available, alas not in a very convenient format for older data. Census data back to 1991 are available from Statistics Canada with an open data licence, digital geographic data is only available back to 2001. Older census data is available in digital format via paid subscription services from private entities with restrictive licences. But all data is available for free as open data in paper format.
Two days ago I gave an example using the new (to CensusMapper) 2001 census data to mix with 2006 data on a common geography based on dissemination areas. A question came up if this works for several censuses, not just for two. Yes, the TongFen package was built with exactly that in mind. Time for a quick demo.
For this we will look at the households spending between 30% and 100% of income on housing in the City of Toronto.
CensusMapper now has 2001 census data, the changes are live and functional and available for mapping and via the data API. We ran some basic verification of the import, and set the metadata for the variables. There may still be some quirks in need of getting ironed out, feedback is appreciated if anyone finds anything that does not look right.
At the same time we finally updated my TongFen package to also include DA level TongFen out of the box, in addition to the CT level that has been working for a while.
