This project represents a    collaborative effort between NCHS and the Bureau of the Census.  The Census' FERRET    system will provide full access to complex large data sets through the Internet.

FERRET will allow you access to    micro-data sets via the World Wide Web. Currently, the 1994 Underlying Cause-of-Death    File, the 1993 National Health Interview Survey and the third National Health and    Nutrition Examination Survey, NHANES III are available via FERRET.      FERRET  provides the capabilities to:Create crosstabsCreate frequenciesCreate a SAS data set for downloadingCreate an ASCII output file where you can: download the file orbring your data into a    spreadsheet

**How to Access FERRET**    You can access FERRET using the link provided above.  You will be asked to sign in    using your e-mail address.  Once the e-mail address has been entered, the next screen    contains a list of the data files available on FERRET at the present time.  You can    then select the files you want to use and proceed using FERRET.

**Guidelines:**    You are encouraged  to read analytical guidelines, the **NCHS Data Use Restrictions**, and    other documentation regarding using each data set and to visit the NCHS Web site areas for    each survey for additional information regarding each data set.  Pay particular    attention to the weighting requirements of each data set.  For some files,    recommended weights have been selected; for others, you can choose weights from the list    of variables.  

This is a test project and your    feedback is welcomed and appreciated.   Please send your comments regarding NCHS data    sets using FERRET to **[email protected]**.
