We don’t think this applies to Vancouver’s geography, but it’s nevertheless an interesting (and quickly explained) hypothesis on the east side vs west side socio-economic population divide of formerly industrial cities in the middle latitudes. Via Cheddar:
“In cosmopolitan hubs around the globe, the east side of the city contains the poorer neighborhood. Cheddar investigates new research from the UK addressing this pattern in city planning.”
While we do have westerly winds, ours was more do with, surprise surprise, speculation: http://montecristomagazine.com/community/a-history-of-downtown-vancouver
The main port location as related to the city’s position on the cardinal points would be a good study. A century or two time lapse would be interesting to see.
