IRS migration data does not represent every U.S. resident (non-filers are underrepresented), a mailing address does not always equal a physical residence, and AGI reflects Year 2 tax returns without proving income was earned after arrival. Use “income moved” or “reported AGI moved,” not “economic impact created.”
