IRS migration data

The IRS has released a new year of state and county level migration flows based on tracking tax returns between 2007 and 2008. As usual, the Missouri Census Data Center has obtained these data and made them available in its public data archive, as well as via its interactive web application that displays a migration profile for any selected county in the U.S.

MDCD used to have to purchase these data on CD-ROM/DVD, but starting this year, the IRS has decided to make the raw files available via a free download site.

You can access the MCDC irsmig data collection, which lets you access the migration profiles menu page.
