SOI Tax Stats - Migration Data

Back to Tax Stats


The 2010–2011 migration data have now been released. SOI will release migration data for 2011–2012 as soon as feasible. Information on the release schedule is forthcoming.


U.S. Population Migration Data

Migration data for the United States are based 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 2011 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.

Important: 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 U.S. Population Migration Data: Strengths and Limitations
