Toronto is facing its worst outbreak of measles in 12 years, with 21 cases since the middle of March. We’re kicking off the Map of the Week project (introduction here) with four maps dealing with vaccination of students in Toronto schools. An important part of the package is parentcentral.ca editor Brandie Weikle explanation of why many Toronto secondary school students don't have the shots otherwise required by law, and what that could mean.
Percentage of the school-aged population (5-18) with vaccination exemptions
As we can see, vaccination exemption is highest in M5J, the FSA that covers the Islands and an area of waterfront condos. It is also high in Bloor West Village/Swansea, High Park, the area south of the Annex to the lakeshore, Seaton Village/Hillcrest, Riverdale and the Beaches, Weston, and the Finch/Bathurst area.
Schools with the highest percentage of pupils with vaccination exemptions: Top 25
Schools with the highest number of unvaccinated pupils: Top 25
Schools with the lowest vaccination rates
The two starting points for this project were two spreadsheets released by Toronto Public Health under access-to-information laws. One showed vaccination statistics for 861 Toronto schools, and the other gave enough address information of students whose parents have gone through the process of exempting them from vaccination that we could map exemption by neighbourhood, more or less.
The polygons on the first map are postal forward sortation areas (FSAs), the first three digits of a postal code. The amalgamated city of Toronto has just over a hundred, though not all are residential. FSAs are a useful unit for building this kind of map – they’re small enough to yield a lot of local information, while at the same time officials handling the FOI request can’t reasonably argue that anyone’s privacy is being compromised.
