About the data
Migration figures come from the official IRS state-to-state files (exemptions ≈ people). Population figures are Census Bureau estimates, and the peak checks every census back to 1910. Income figures are the total income (AGI) movers reported in the same IRS files. Dollars are not adjusted for inflation, and household averages divide by the number of returns. Years marked † had a change in how the IRS built the files. Full details, caveats, and a suggested citation on the methodology page.
