Reading Survey of Program Dymanics (SPD) Files with SAS, SPSS, or Stata

The SAS, SPSS, and Stata files were created by Jean Roth at the NBER to make access to the Census' Survey of Program Dynamics Files easier.

The corresponding data files are available at the Census/BLS Data Download page. Also, the Census has old and new data extraction tools for the more recent files. Internal users can access these files and corresponding data in a UNIX shell at /homes/data/spd or on an NBER PC at Network Neighborhood --> NBER --> home --> data --> spd

To download files in Internet Explorer, right click on them and select "Save Target As...". If you want to print the files, cut out the parts you don't want first. Each file has thousands of lines.

Updates and changes.
