- Census Profile 2016, Statistics Canada
- Median total income in 2015 among recipients ($ CAN) for entire Toronto CMA = 31,705, which was used to normalize census tracts as below or above 100% of this level
- Inspired by https://thelocal.to/mapping-our-divisions
- Used http://Mapshaper.org to reproject original shapefiles to WGS84 and edit features according to sources.
- Census tract boundaries 2016 were simplified in Mapshaper.org to reduce file size from 5MB to 1MB.
- Used Hans Hack Gimme Geodata tool http://hanshack.com/geotools/gimmegeodata to extract current and historical political boundaries in GeoJSON format from Open Street Map for areas that were dissolved into Toronto:
- Etobicoke (background: last change to its boundaries (before it was dissolved completely) was in 1967, reflected in the 1971 decennial census maps: correspondended to tracts 200-250 (see gtf71cbk.pdf, page 27)
- York (background: Township/later called Borough of York: corresponded to 1971 map tracts 150-176 (see gtf71cbk.pdf, page 26)
- Scarbourough
- Reconstructed boundary for (Village of) Forest Hill from 1961 Canadian census (last time it appeared as separate municipality in decennial census): corresponded to tracts 150, 151, 152, and 153 in the 1961 census DLI files. Does not align perfectly with other geodata but good enough for now
