A roommate or family. Yes I do.
Well according to the Zillow Group Consumer Housing Trends, which they gather data annually, the figure of US adults living in doubled up (non-spousal) housing is 32%
The US city with the 2nd highest percentage is the Los Angeles-Long Beach-Anaheim area at 45.5% which is still less than majority. They are right behind Honolulu.
The next highest major city in CA is San Francisco with 38%
As for the entire state of California that would probably put the average anywhere from 35 - 40% which is not majority.
That is what I mean when I say people think that every city in CA is either Los Angeles or San Fran. I am not saying it's easy, but on average you can get by with $40K in CA. Maybe not in LA or San Fran, but in many other places by majority, it's possible. And you may not live a comfortable lifestyle, but that is what the term "Getting By" means.
