Accessing the Public Data Files

Data for 1989-2014 are available in SAS, Microsoft Excel, and CSV (comma separated values) format for MS-DOS compatible computers and Macintosh computers.

The SAS files, which have been compressed to facilitate downloading, can be read into other data analysis programs, such as SPSS and STATA. The Windows operating system comes with software for decompressing (unzipping) files. UNIX/LINUX distributions also come with decompressing software. Further guidance for opening a compressed file is available here:
