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.

Colonne	Type	Description
filing_year	integer	The later filing year of the matched return pair (year-2 return); migration measured between filing_year-1 and filing_year addresses. (unit: year)
data_year	string	SOI data-year label for the matched pair, e.g. '2022-2023'.
state_fips	string	Two-digit FIPS code of the filing geography (50 states + DC); primary join key with filing_year.
state_abbr	string	USPS state abbreviation.
state_name	string	Provider-verbatim geography name from the SOI gross file.
country_code	string	ISO alpha-3 country code (USA for every row). (unit: ISO 3166-1 alpha-3)
method_series	string	SOI matching-methodology series: 'soi-2011' for filing years 2017-2021, 'soi-2022' for 2022-2023. The 2022-2023 matching update added ~5% more matched returns, so the two series are not directly comparable.
inflow_returns	integer	Number of matched returns that moved INTO the state from another US state between the two filing years (SOI origin code 97, 'Total Migration-US'). (unit: returns)
inflow_individuals	integer	Number of personal exemptions on in-migrant returns, approximating the number of individuals. (unit: individuals)
inflow_agi_k	float	Aggregate adjusted gross income of in-migrant returns, from the year-2 return. (unit: USD thousands)
inflow_foreign_returns	integer	Matched returns that moved into the state from a foreign address (SOI origin code 98). (unit: returns)
inflow_foreign_individuals	integer	Personal exemptions on foreign in-migrant returns. (unit: individuals)
inflow_foreign_agi_k	float	Aggregate AGI of foreign in-migrant returns. (unit: USD thousands)
outflow_returns	integer	Number of matched returns that moved OUT of the state to another US state (SOI destination code 97). (unit: returns)
outflow_individuals	integer	Personal exemptions on out-migrant returns. (unit: individuals)
outflow_agi_k	float	Aggregate AGI of out-migrant returns. (unit: USD thousands)
outflow_foreign_returns	integer	Matched returns that moved out of the state to a foreign address (SOI destination code 98). (unit: returns)
outflow_foreign_individuals	integer	Personal exemptions on foreign out-migrant returns. (unit: individuals)
outflow_foreign_agi_k	float	Aggregate AGI of foreign out-migrant returns. (unit: USD thousands)
net_returns	integer	US interstate net migration in returns: inflow_returns minus outflow_returns. Positive = net gainer. (unit: returns)
net_individuals	integer	US interstate net migration in individuals. (unit: individuals)
net_agi_k	float	US interstate net migration in aggregate AGI. (unit: USD thousands)
net_returns_total	integer	Net migration in returns including foreign flows. (unit: returns)
nonmigrant_returns	integer	Matched returns that did not change state between the two filing years (SOI gross file, all ages); denominator of the net migration rate. (unit: returns)
net_migration_rate_per_1000	float	SOI's published net migration rate: net_returns / (nonmigrant_returns + outflow_returns) * 1000. Headline comparability metric across states of different sizes. (unit: per 1,000 returns)
net_rate_rank	integer	Per-filing-year rank of net_migration_rate_per_1000 across the 51 geographies (1 = strongest net inflow; deterministic: rate desc, state FIPS asc). (unit: rank)
net_returns_rank	integer	Per-filing-year rank of net_returns (1 = largest net inflow in returns; deterministic). (unit: rank)
avg_agi_inmigrant_usd	float	Average AGI per in-migrant return (inflow_agi_k * 1000 / inflow_returns). (unit: USD)
avg_agi_outmigrant_usd	float	Average AGI per out-migrant return. (unit: USD)
wealth_ratio	float	avg_agi_inmigrant_usd / avg_agi_outmigrant_usd. Above 1 means in-migrants are richer on average than out-migrants (income 'brain gain'). (unit: ratio)
migration_churn_pct	float	(inflow_returns + outflow_returns) / (nonmigrant_returns + outflow_returns) * 100: share of the filing population that moved interstate. (unit: percent)
inflow_top3_origins	string	Three largest state-to-state inflow corridors as 'ABBR:returns' pairs (e.g. 'NY:43187, GA:23475, CA:20241'); foreign and suppressed (<10 returns) flows excluded.
outflow_top3_dests	string	Three largest state-to-state outflow corridors as 'ABBR:returns' pairs.
inflow_yoy_pct	float	Year-over-year percent change of inflow_returns, computed only within a methodology series; null across the 2021->2022 series break and for 2017. (unit: percent)
outflow_yoy_pct	float	Year-over-year percent change of outflow_returns, within-series only. (unit: percent)
net_returns_yoy_delta	float	Year-over-year absolute change of net_returns (levels, since net crosses zero), within-series only. (unit: returns)
provenance_url	string	The IRS SOI migration-data page covering this data year (per-row provenance).
row_hash	string	Deterministic 16-hex row hash of state_fips + filing_year (idempotency).
