File Format Options and Contents

You will download a single self-extracting executable PKZip® data file that contains all the data files and the documentation. All databases are available in ASCII and MS Access® format. Starting with FNDDS version 3.0, the database is also available in SAS® format.

  • ASCII delimited data files are organized in a relational format and are best used with a relational database management system.
  • MS Access® contains the data imported into a database in MS Access® format. You need MS Access 2000 or higher to use this file.
  • SAS® contains the data in SAS formatted files.

Documentation is included in a PDF file with each download.

Record counts, i.e., the number of records in each data file, are also included with each download. In the FNDDS databases, the record counts are tabulated in a file named FNDDSRecCount. In the vitamins A and E database, record counts are on page 3 of the documentation.

Disk Space Requirements

The amount of free disk space needed to store the uncompressed files is:

  • FNDDS (version 1.0, 2.0, 3.0, 4.1, or 5.0): about 60 mb
  • NHANES 1999-2000 Vitamins A and E database: about 3 mb
