from the comments here:

but not the other two.
Hawaii is very expensive and you are very far from everywhere else. Florida is losing lots of people, not just young.

If I could afford to leave Florida—and could figure out a place I’d rather be—I’d have been out of here a decade ago.

so this is a topic that will have to be revisited in about 30 years when most of us are gone.

It seems the real prroblem in most of the states losing population is disparity between wages and housing. Since states have failed to manage housing construction, opting for the high tax base luxury housing instead of lower tax base apartments and townhouses in inner suburbs, the only way they now have to hang onlo productive population is to increase wages, but I hardly see a stampede to do that. I think the magical thinking is that all they have to do is wait for all the Boomers to die and housing prices will somehow magically decrease and young people will be happier to stay and work for peanuts.

Housing is very expensive. Property taxes are very high. We lived in NH on the seacoast and it’s really pricey.

There also is not a ton of opportunity for young people. Most head to MA.
