Internal Revenue Service (IRS). Statistics of Income (SOI) Tax Stats: Migration Data

The latest migration data from the Internal Revenue Service (IRS) is now available in mySidewalk.

Migration Data Is Here — Who's Moving In, Who's Moving Out, and the Income Moving With Them

Is your community gaining residents or losing them? And where are they coming from and going?

New migration data from the Internal Revenue Service (IRS) Statistics of Income (SOI) Division is now available in mySidewalk. It covers every state and county across 12 periods, from 2011–2012 through 2022–2023. You can see how many people moved in and out, where they came from and went, and the combined income that moved with them — ready to pair with the housing, income, and employment data already in mySidewalk.


What's new

28 indicators in six groupings:

  • Population inflow — total, and by origin: other counties in the same state, other states, and outside the US

  • Population outflow — total, and by destination, with the same breakouts

  • Adjusted gross income (AGI) inflow and outflow — the combined income on the returns of people moving in and moving away, with the same breakouts

  • Net migration — inflow minus outflow, split into domestic and international

  • Net AGI migration — whether more income is moving in than moving out, split into domestic and international

  • Non-movers — the population and AGI of people who stayed in the same county

How moves are counted

The IRS matches federal income tax returns filed in two consecutive years and compares their mailing addresses. When the county changes, everyone on that return — filers and dependents — counts as a mover. Each period is a pair of years: 2022–2023 compares returns filed in 2022 with returns filed in 2023.

A few things to keep in mind. People who don't file, or file for the first time, aren't counted. State values include moves between counties within the state, so they run larger than the IRS state tables and Census state-to-state figures; net migration isn't affected. And the IRS improved its return matching for 2022–2023, so part of any jump into that period comes from the method, not from more moving.

Where you can use it

This data is available at the county and state levels. Because every figure is defined by moves between counties, it can't be apportioned to custom geographies.

Put it to work with Sidekick

Ask Sidekick about your community — the same way you'd ask a colleague:

  • Give me an overview of migration in [your county].
  • How has net migration in [your county] changed from 2011–2012 to 2022–2023?"
  • Where are people moving to [your county] coming from: other counties in the state, other states, or outside the US?
  • How does migration in [your county] compare with neighboring counties?

  • Is [your county] gaining or losing income through migration?

  • Is housing construction in [your county] keeping up with the people moving in? I'm working on our housing needs assessment

  • Create talking points on who's moving into and out of [your county] for our economic development board.


Whether you're preparing a housing needs assessment, an economic development strategy, or a budget forecast, the data is ready when you are.
