SOI Tax Stats - State-to-state migration database files

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.

Data files are available for download in two formats:

• Generic ASCII data files (.dat file extension)—These require a record layout to read.
• Comma Separated Values files (.csv file extension)—Data items are separated by commas, where each new line represents a new row.
