Ah, I was wondering about North Carolina. From a Pennsylvanian perspective, it seems like everyone is moving to there and Georgia. This might be East Coast bias.
I'm from Tennessee, and it was my first guess. It seems like every new person that moves here is from California. But hey, when you can buy a mansion on acres of land for the same price as a 700 sq. ft. studio, who can blame 'em? lol
Sarcasm aside, West Virginia is unironically a great place to move if you're looking for a place to settle once you're retired or if you're bringing a job with you, very beautiful and affordable, not so good if you're looking for a job once you move though.
These trends can be easily explained by comparing housing policies in California and Texas. Austin's skyline is full of cranes, building new office buildings and apartment buildings, while its suburbs continue to grow. San Francisco, meanwhile, has its city councilmembers actively working to downzone their districts. People will move to where they can afford to live.
I've seen people complain and say things like "Don't California my Texas" when historically people have always moved states. What comes to mind is during the Dust Bowl of the 1930s people moved from Texas, Oklahoma, and Kansas to California is search of work and many of them stayed there. And since late 20th century people have also been moving out of the Midwest and Northeast down to the south and the west. The housing issues that California has dealt with has been ongoing for decades and is not the fault of everyday people, some of whom have decided to move out of state.
