BC schools are about to restart, and there is a high level of anxiety among parents and teachers. In this post we will
outline some common concerns, and run modelling adapted from the University of Washington network-based model to test the relative effectiveness of various test, trace, and isolate (TTI) scenarios. Cases in schools There will be cases at schools. Quebec already has over 180 schools with reported cases, Ontario had over 7 on their first day of school.

Do people select cities from diverse alternatives? Or do cities select residents from diverse flows of people?
The answer is pretty much: both.
People can look around and consider where they want to end up. And cities, through municipal policies, can and do work to select their residents. EXCEPT cities can’t do this directly. At least across North America, cities generally aren’t allowed to establish and maintain their own immigration policies.
I was browsing the Canadian Perspectives Survey Series 3 on Resuming Economic and Social Activities During COVID-19 and thought that some of the results were interesting. I don’t have time to do a detailed post on this, but thought that others might enjoy a quick series of graphs highlighting some of the result. The survey is only released as microdata, and I have not seen much uptake or reporting other than the high-level results put out by StatCan in The Daily.
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.
Mixing census data with COVID-19 case and mortality data seems like an obvious thing to do when trying to understand how COVID-19 affects different groups. But it’s only of very limited use. COVID-19 data is only (openly) available on coarse geographies and can only be matched at the ecological level. Deriving individual level relationships from this is extremely ambitious. At best, it can inform decisions on what individual level data should be collected moving forward.
