This turned out to be a lot easier than expected. The City lumps each zoning district into fairly broad categories and it only took about 5 minutes to clean up the obviously missing metadata. Here's how much land area (as a percent of all zoned area in Vancouver) each one takes up:
59.4% One Family Dwelling
14.3% Comprehensive Development
6.2% Multiple Family Dwelling
6.1% Two Family Dwelling
3.9% Light Industrial
3.9% Commercial
3.3% Industrial
2.5% Limited Agricultural
0.3% Historic Area
Puts some perspective on the common beliefs that Vancouver is A) a leader when it comes to dense, environmentally friendly city-building, or B) an unregulated metropolis where developers can build anything they want.
Methodology: Imported the City's SHP data from
here into Cartographica, cleaned up missing categories (the correct category was always clear from the zoning district name), then copied the data into a spreadsheet with a pivot table for the summary. Message me if you want the spreadsheet.
