US county income migration (IRS Statistics of Income, keyless)
Annual US county income-migration panel, 2018-2019 onward: IRS Statistics of Income county-to-county migration files (keyless), reduced to verified per-county totals with fail-loud accounting identities. Net AGI flow (inflow minus outflow, $1,000s), mean arriving vs departing household income and the arrival premium, migration turnover, net income per resident return, a documented 0-100 income-migration heat score with tiers, and a methodology-break flag on the 2022-2023 enhanced-matching vintage. One row per county x tax-year pair (~14k rows, 5 vintages); suppressed micro-counties are dropped and counted, never imputed. Sibling dataset `us_county_migration_annual` covers the 2022-2023 vintage only; this panel spans five vintages (2018-2019 through 2022-2023) with additional intelligence: the heat score, tiers, turnover, and the methodology-break flag. Who joins this: online shops join county_fips + year to test whether net income migration leads local demand; subscription businesses use the tier and arrival premium as geo features for churn/expansion models; sales teams weight territories by the heat score.
