IRS Statistics of Income county-to-county migration, tax years 2022->2023 (keyless official xlsx, U.S. public domain): per-county panel (~3,140 counties + DC) of official inflow/outflow/net migration of tax filers, individuals and AGI, non-migrant filer base, net migration rate per 1,000 filers, average AGI per return in vs out with a wealth-flow delta, foreign and disclosure-bundled "other" flow residuals, top-5 inflow/outflow corridors from disclosed (>=20-return) county pairs, inflow concentration (HHI), a documented 0-100 migration-magnet score with national rank and e1-e5 tiers, and wealth-gain / foreign-hub / high-churn flags. Identity-gated: official 96/000 totals reconcile to detail+other+foreign per county; suppressed (<20-return) flows are bundled by the publisher into "other" residuals, never zeroed. Sample use: order by magnet_rank for the strongest magnets, or filter state_abbr for within-state migration geography.
