Well, perhaps  it's not a slam dunk, Publius.

Caveat says it all..."Does not include Foreign Migration"  For California and New York that little exclusion is not trivial.  I would guess without that Foreign immigration the domestic migration would be reduced, at least for California.

Why would you include foreign migration is you are trying to measure domestic migration?

A good guess would be that most of California's in-migration is foreign and most of its out-migration is domestic.  That is what it means to be a "gateway state."  California and New York have been subsidizing the rest of the country by taking a large proportion of the nation's immigrants and then educating their children to become major contributors to the economies of all 50 states.

Here is another hypothesis: California exports many college graduates to other states--for example, many of you here on this board who are Stanford graduates--and this drives up the "exported income" side of the ledger.  Meanwhile, California imports more H1B visa workers than any other state and all of their incomes are excluded by the methodology, and this in turn holds down the "imported income" side of the ledger.
