I will respond to the one factual claim buried in all the emotional outrage. Let's look at the 2021 American Community Survey. How long someone has lived in a unit is called "tenure". You want to look at tenure for renters, which is this table: https://data.census.gov/table?q=san+francisco&t=Owner/Renter... Here is the data: Renter occupied: 427300 Moved in 2019 or later 170948 Moved in 2015 to 2018 70878 Moved in 20…
FYI your link doesn't go directly to the specific table you are using, which I believe is B25026. I am using S2502.
FYI, S2502 is not the right table to use because it is looking at housing units rather than people, whereas you want to measure people. So if there is a apartment that is owner occupied and rents out a room to a tenant, then this is an owner occupied unit for purposes of S2502. This also applies to in-laws.
Again, I'm not saying all renters are transient. There is certainly a core of renters -- I think 28% or 1/3 is a good estimate. That is, from living in SF for a while and spending a lot of time with this data, I'd say a good 1/3 of renters in SF are just there for a couple of years to have fun and will move out quickly. They have no roots at all. 1/3 are a bit in the middle, where they think they have roots but decide to leave when they have children or get married and the realities of family life in SF hit them. 1/3 are all in.
So even though you have a 60-40 split in terms of renters/owners, the actual split of people who care about zoning and local issues is heavily in favor of owners. This is why the city council is constituted as it is. It's not voter suppression. It's not dirty tricks. It's just reflecting the demands of the population that cares about these issues. That's why you have things like crazy shadow ordinances preventing tall buildings from being built, or why the 8 Washington debacle happened.
