@CBBarnett do you have that graph for other neighborhoods?
And I absolutely agree with you. There is more to the story of downtown than office vacancy.
Here's the big picture of everything south of the river before the escarpment starts (sorry Bankview, honourable mention to you but you are too hilly to include in my random selection of communties). Also sorry I forgot Eau Claire but finished my graphs already
Here's some data someone might find interesting on peak/minimum population, what year and how it compares to 2019:
Obvious story is the Beltline, but Downtown Commercial Core has long been a source of substantial population base, particularly how it's been distributed mainly to the western part of the Commercial Core. Lower Mount Royal is another sleeper hit - it doesn't have a growth story, but has been a stable, very dense population base to support area retail along 17th for decades.
Applying these numbers to context of the current projects and their scale, Sunalta Heights (333 units or ~500 - 600 people) or the Superstore Arris tower (~300 units/500 people) would seriously change their neighbourhood's numbers. A single building would increase the local community population by 10%-20%.
Toss in Eau Claire's 2,000 residents, the total population of this area is 58,000+ in 2019.
