PUF NCDB Supported Tools and Resources

NCDB PUF data files are provided to investigators in a flat text file format, and can be read with any standard statistical software package of the investigator's choosing. Refer to the Quick Start document for variable lengths, types, labels, and formats, if you use a software other than SAS, SPSS, or STATA, and need to create your own script.

The NCDB provided PUF investigators with three "parsing" scripts. These files permit investigators to import the PUF file and assign value and variable labels. The item and variable names in the scripts are the same as those documented in the on-line PUF Data Dictionary. Investigators must have SAS, SPSS/PASW, or STATA software installed on your computer to be able to use these scripts. The syntax in these scripts is applicable only to the 2015 PUF. The Revisions tab contains links to previous versions of the PUF item definitions and parsing scripts if you are analyzing the 2011, 2012, 2013 or 2014 PUF data. These three scripts include:

  • input statements that will read the NCDB PUF file and assign variable names;
  • variable labels;
  • data item specific format statements (SAS) or value labels (SPSS/PASW, STATA);
  • instructions on how to use the scripts to read in the data files
