I mean...logically you can't say that...because if we did no one could move in....And you also can't say with certainty that they people are electing NIMBYs who then shape policy. Right?

I really don't care if people move here, but it is interesting that Northern CA has some of the highest rates of single family homes....and Seattle is only just a bit behind them now. https://www.youtube.com/watch?v=CCOdQsZa15o

I think it's just logical to look at the trends in regions and compare the migration from that region with those trends. That's reasonable. People tend to move to escape trends they don't like. High housing prices, increased taxes, changes in zoning they feel will change their neighborhoods, etc. It's not really radical.
