IRS Statistics of Income
Annual US state migration intelligence from IRS Statistics of Income migration data (filing years 2017-2023, 50 states + DC): US interstate inflow/outflow of tax returns, individuals and adjusted gross income (AGI in $ thousands, year-2 return), net flows, SOI's net migration rate per 1,000 filing returns, per-year net ranks, a wealth signal (average AGI of in-migrants vs out-migrants), migration churn, the top-3 inflow/outflow corridors per state-year, and within-series year-over-year momentum. SOI's 2022-2023 matching update added ~5% more matched returns, so 2017-2021 and 2022-2023 are separate methodology series (2022 YoY cells null by design). Caveats: matched filers only (not the full US population); mailing addresses may not be residences; state detail flows under 10 returns are suppressed. IRS SOI data are US federal public domain (17 U.S.C. 105, commercial reuse allowed); source: IRS Statistics of Income.
