Oh my god. This is horrifying. The US HUD affordable housing income limits for San Francisco County shot up $10,000 in ONE YEAR. According to the federal government, a low-income family of four in San Francisco is now any such family making $140,000 per year.
This is happening because San Francisco is artificially constraining the supply of housing that can be provided in the market, so the fixed amount of housing is being bid up by the increasingly wealthy upper class that can afford SF.
Subsidized housing will get even more scarce, as the population of those in need expands, and it'll get more expensive, as families’ expected incomes rise. Constraining the supply of market rate housing in San Francisco is most hurting affordable housing and those in most need.
Sorry I added the second graph twice in the first tweet, that's just a typo.
