A lot of people are saying to themselves, "We're not in Kansas anymore," after moving out of the state. Kansas is another state with really high rates of outward migration, and this is mostly due to high-paying jobs and a lack of things to do. The overall unemployment rate is actually pretty low in the state, but a lot of those jobs don't pay very well, especially if you're a graduate who just spent a lot of money on a degree.
Kansas's overall population has been seesawing over the last decade and it's unclear if it'll continue to lose people or if it can manage to bounce back somehow, but the tornadoes make it a hard sell.
