The idea that Californians are leaving in droves has so far been mostly anecdotal and not supported by real data. The IRS publishes migration data for taxpayers at the state and county level here: https://www.irs.gov/statistics/soi-tax-stats-migration-data This seems to be the best data we have, since it covers most of the population and accounts for dependents.
They've only got data from tax returns processed through the 2018 tax year, but for that year California ranks 47th out of 51 (including DC) for outflow rates, with only the people of Minnesota, Wisconsin, Ohio and Michigan more likely to stay put. In raw numbers, more Californians do leave than Floridians (2nd most left state) or Texans (3rd most left state), but when you normalize for population, it turns out that the places people are most likely to leave are D.C, Alaska, Hawaii, Wyoming and North Dakota.
I think it's going to be very interesting to see the data in a couple of years, once the 2020 returns are processed, to find out how Covid and work-from-home trends really affected migration patterns.
Not trying to turn this into a dump-on-Cali thread. I have heard (anecdotally) that Uhauls are more expensive going out than coming into Cali. I google'd this: https://www.businessinsider.com/uha...os-angeles-san-francisco-moving-trucks-2020-9 which suggests it may be true. I often heard that Cali is moving to TX and TX isn't happy - but that may be a joke.
Living in HI, we have been seeing similar (minus the Uhaul and TX part, heh, heh) stories of folks moving out. It's not actually noticeable, say, on the roads. However, in our building, in the past 10 years we have lost (to the mainland) the next-door neighbors twice and both the upstairs and downstairs neighbors once each. As we live on an end unit, that means that all 3 of our neighbors that we share a common wall/floor/ceiling with have moved to the mainland a total of 4 times in 10 years. Not sure what that really means, but there it is. Could it be us? Naaaaahhhhh! We are good neighbors, so YMMV.
