Fascinating

Check out this amazing interactive map from Forbes (hat-tip to Ryan Streeter at AEI's American Blog). Click on any county in the United States, and you can see color-coded lines to every other county that people either moved in or out from in 2008 (red indicates more people leaving that county, black indicates more people entering).

There's plenty to see here, but the New York City area counties are particularly interesting; the out-migration from there to no-state-income-tax Florida is nothing short of staggering.
