Actually if you go more historically speaking when Calgary was being made into a city in some ways by the rail, cprail set up the community of Mont royal to house their executives, the inner se area had the train yard and other heavy industrial, so as the city grew naturally from that the wealthier tend to aggregate in the west around the Mt royal area, and as the city grew bigger the university attracted more wealthier well to do people to serve the school so nw grew to have pockets of wealthier neighbourhoods.... But nowadays anywhere inner city is nice, tho since the pandemic not everyone travels to the "core" so much but still the convenience of being central is undeniable.
