SOI Tax Stats - U.S. Population State and County Migration Data (1990-2016)
- Internal Revenue Service (IRS)
AbstractThe 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 migrated
- Number of personal exemptions claimed, which approximates the number of individuals
- Total adjusted gross income, starting with Filing Year 1995
- Aggregate 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.
Technical InformationResponse Rates: The data used to produce migration data products come from individual income tax returns filed prior to late September of each calendar year and represent between 95 and 98 percent of total annual filings.

The data used to produce migration data products come from individual income tax returns filed prior to late September of each calendar year and represent between 95 and 98 percent of total annual filings. However, since returns filed after September are not included, totals shown in migration data tables will not match analogous totals reported in other IRS statistical data products. For more information, see the U.S. Population Migration Data: Strengths and Limitations documentation.
Beginning with data for 2011–2012, SOI has introduced a number of enhancements to improve the data’s overall quality, as well as provide a new series of information. For more information, see the SOI Migration Data: A New Approach Documentation.
