SF used to be about 780k in 2010, before the pandemic, it was over 880k, so it is reverting back to 2010 levels...
It is not alarming right now, but if the trend continues next year, it is going to be a major problem for the tax revenue. Raising taxes will not help in stoping the bleeding and make things worse... (SF is a city of renters, and they can easily leave)
And yet, a cheaper COL "build-up" city like NYC is experiencing similar flight due particularly to high density. And SF is (or was) the second densest large city in the US.
Only in the context of SF is NYC (esp. Manhattan and parts of Brooklyn) a cheaper CoL city. (Though I think it does demonstrate that building up isn't some magical elixir for housing prices. See also e.g. Hong Kong.)
