SOI Tax Stats - U.S. Population State and County Migration Data (1990-2016)

The IRS Statistics of Income Division (SOI), in collaboration
with the U.S. Census Bureau, has released migration
data for the United States for several decades. These data
are an important source of information detailing the movement
of individuals from one location to another. SOI bases these
data on year-to-year address changes reported on individual income tax returns filed with the IRS. They present migration patterns by State or by county for the entire United States and are available for inflows—the number of new residents who moved to a State or county and where they migrated from, and outflows—the number of residents leaving a State or county and where they went. The data are available for Filing Years 1991 through 2016 and include:Number of returns filed, which approximates the number of households that migratedNumber of personal exemptions claimed, which approximates the number of individualsTotal adjusted gross income, starting with Filing Year 1995Aggregate migration flows at the State level, by the size of adjusted gross income (AGI) and age of the primary taxpayer, starting with Filing Year 2011.***Microdata: Yes Level of Analysis: State; Local - County Variables Present: Yes File Layout: .xls Codebook: Yes Methods: Yes Weights (with appropriate documentation): No Publications: No Aggregate Data: Yes
