> I'd imagine that this methodology doesn't affect things too much, considering that around 70% of high school graduates go to colleges in-state.

So a full 30% go to colleges out of state? And I would wager that quite a few come to be close to family afterwards. That's a huge swing in the data.

Especially as people who have left their state to go to college have already left their state to advance their lives, regardless of what they do later.
