In case anyone is wondering SF county (& many of the counties around it) pay 16.2% of their income in taxes putting them in the top 20 of the country [1]. SF/Oakland have some of the longest waiting for permits for residential at 10.2 months on average [2]
I can't seem to find any good sources on exactly how much public aid is spent.
Because I was wondering, the SF MSA ranked 25th out of ~1k in terms of worst income inequality [3]
All of these data points come from different sources and from different years.
