About the data
Corridors are IRS county-to-county migration flows added up into metro areas (2023 Census metro definitions; exemptions ≈ people). "Rest of" entries cover a state's counties outside any featured metro. The IRS hides corridors with fewer than 20 returns, so the lists here cover about 73% of inbound and 66% of outbound movers in 2022–23. The in, out, and net totals count everyone. Income figures are the total income (AGI) movers reported, from the complete county totals. Dollars are not adjusted for inflation, and household averages divide by the number of returns. Population figures are Census Bureau estimates; the peak covers records since 2000. Years marked † had a change in how the IRS built the files. Full details on the methodology page.
