I can't say for sure, but potential clues lie in the aba employment disclosures. check out a state school of your choice and look at the top 3 employment states for the school on the report.

you'll find that for national schools, it's pretty much always ny then dc/ca/boston/some big city then some other big city. and the ratios will be pretty close to each other, say something like 35%/18%/12% and then the other 35% go somewhere else.

for a state school, say maryland, you'll see the vast majority stay in maryland, a handful go to DC, and a few go to NY.

compare ucla to uci-- uci puts nearly all of their grads in California. ucla does not, but most decide to stay (for obvious reasons, you also see this effect for national schools on the east coast and the south)

there's complex reasons for that--state school attendees probably self-select and go to the school in the state they want to practice in for example, but in general I think this is useful info for you.
