Example: Access to Data• Public-Use Data Files (micro-data) (1973-2004)

Downloadable data files:Notice: Currently, NAMCS and NHAMCS public-use files for 1993-2004 contain sample design variables in masked form. The initial release of the 2000-2004 public-use files included masked sample design variables. We re-released the 1993-99 NAMCS and NHAMCS files to include these variables. For re-released files, file names and layouts are essentially the same, but the design variables were appended to each file according to a generic file layout that is available for downloading below. Public-use files for previous years of data will be re-released with masked sample design variables on an ongoing basis.

• However, data users should note that, beginning with the 2002 public use files, two new masked design variables were added to the file, for use with statistical software that assumes a single stage of sampling. For the 2003 public use files and beyond, the decision was made to include only these two masked design variables for variance estimation. Therefore, data users who wish to combine years of data from 2003 and beyond with years prior to 2002 will need to create these two variables for each file prior to 2002. A technical paper, Using Ultimate Cluster Models with NAMCS and NHAMCS Public Use Files, gives instructions. Click here to view/download 34 KB. NAMCS, 1993-2004 NAMCS, 1973-1992 NHAMCS, 1992-2004
