Note that the sample population was recruited through Facebook and Instagram ads, which is not exactly a random sample. In particular, it's likely to skew toward younger residents (who tend to be more mobile in general), toward people who are not parents (who have more time to be on social media), and toward people who click on ads and have time to fill out a survey. https://jointventure.org/images/stories/pdf/sv-poll-2021-report.pdf https://jointventure.org/images/stories/pdf/sv-poll-2021-rep...

There are enough people on Facebook and Instagram that you could have a demographically balanced/representative sample.

  It is demographically balanced - their sampling technique made sure of that. My point is that it's probably not balanced by free time or choice of activity. It's going to be biased toward people who spend time on Instagram and Facebook, simply because that's what they draw their sample from. So someone like me, who spends the bulk of my time either working, playing with my kids, or seeing friends in person isn't going to be in the sample at all. I'd argue that such people will be overrepresented among folks who are planning to stay in the Bay Area, simply because they're the only ones who can afford to. Was talking with a neighbor recently who's been in the neighborhood for two generations (50+ years), and he said that it used to be mixed middle-class with all sorts of people living there, but among people who bought in the last 10 years, it's been 100% tech.

    I agree that it's not balanced by free time. I think all surveys will have this problem. All of the respondents need to have enough free time and be willing to fill out the survey. I don't think that's a big problem with the methodology of trying to measure sentiment of a large population of people.
