Why can't I open the Stata files from the ICPSR website?

Stata released version 13 of their software last year, and ICPSR changed its processing software to output the new version of Stata.

Unfortunately, we found out after the fact that files formatted for version 13 will not open in older versions of Stata, even though version 13 can open Stata files formatted for older versions of the software.

For this reason, we changed our system to output version 12 Stata files instead.

We did not, however, go back and re-run all of our new studies. Studies released or updated between January 2, 2014 and June 30, 2014 may include version 13 Stata files. If you have any file problems, please contact ICPSR user support and we can assist you with file conversion problems.
