>Note: Those who grew up in one state, went to college in another, and then moved again are counted as migrating from the state where they attended college.
Also, 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.
Each of those is an interesting data point with different ramifications.

"People who grew up in one state, went to college in another and then moved somewhere else are counted as migrating from the state where they attended college"
To me "somewhere else" means a third state neither KY or MA.
