Cancensus
We have previously look at T1FF tax data which is an extremely rich annual administrative data source. The cansim tables have a range of variables to inform about incomes of individuals, families (sliced by number of children, including zero children), low income statistics, and just statistics about the number of taxfilers and dependants by age.
It’s available on cansim for Canada overall, the provinces and CMAs/CAs. That’s great, but sometimes it’s nice to have finer geographic detail.

Empty Homes Taxes are back in the news!
In a very short time period, we’ve got Vancouver raising its Empty Homes Tax rate from 1% to 3%, based in part on a report from CMHC about a sharp rise in condos on the rental market, we’ve got Toronto eyeing its own Empty Homes Tax, and now reports suggest that even Ottawa is considering getting in on the game.
The tongfen R package is now on CRAN, so it’s time for an overview post. Tongfen has changed a bit since it’s inception and is now a lot more flexible but slightly more abstract to use.
What is tongfen? Tongfen, 通分 in Chinese, generally denotes the process of bringing two fractions onto the least common denominator. This is akin to the problem of making data on different but congruent geographies comparable by finding a least common geography.
At the end of June StatCan released an interesting census tract level metric, dubbed the D-index, measuring how much the income distribution in each census tract differs from the metro-wide distribution, and we decided to take it for a test drive.
We are a bit of a sucker for this kind of fine-geography index. Condensing our wealth of information into a single number is an interesting exercise that involves lots of attention to detail.
Canadian 1996 census data is now avaiable on CensusMapper for anyone to make maps, for API access and via the {cancensus} R package. Yay!
The geographic data is not freely available from Statistics Canada, but can be custom ordered (via a small processing fee). Now the data is freely available on CensusMapper. The geographic data is slightly processed, we clipped out water areas and geographies from CSD upward are slightly simplified for better mapping performance as usual on CensusMapper.
