SOI Tax Stats - Migration Data
State and county migration statistics will continue to be produced and posted on this site. Statistics for 1990 through 2010 are currently available. Statistics for 2011 will be posted as soon as they are completed. In addition, work is underway at IRS and the Bureau of the Census to develop additional migration statistics that take advantage of improved data that have recently become available.
Migration data for the United States are based on year-to-year address changes reported on individual income tax returns filed with the IRS.
The data 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 county or state and where they migrated from, and outflows—the number of residents leaving a county or state and where they went.
The data are available for Filing Years 1991 through 2009 and include:
Number of returns (which approximates the number of households that migrated)
Number of personal exemptions (which approximates the number of individuals who migrated)
Total adjusted gross income of the migrants (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.
