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.

The data 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.
