1993 AHEAD (Wave 1) Re-Release (Final, Version 2.10) Information: Distribution Files Reformatted
This information pertains to the re-release of the 1993 AHEAD dataset; it is derived from a Data Alert published on 02/04/2003
The 1993 distribution files have been re-released as .zip files instead of .exe files.
The data files have been re-released in our standard format -- ASCII data (.DA) files and associated program statement files for SAS, SPSS and Stata users. This will facilitate usage by analysts using SPSS and Stata as formerly the 1993 data files were available only as SAS internal and SAS transport files. In addition:
The contents of most of the documentation files have not changed. The codebook documentation and questionnaire are now distributed only in Adobe .PDF format.
Users should download the ASCII data files, one set of program statement files, and questionnaire and documentation (codebook) files. See the revised Readme document and the Changes document for further details.
