Public-Use
Data Files (micro-data)(1973-2002) Downloadable data files: Notice:
We are pleased to offer enhanced NAMCS and NHAMCS public-use files for 1993-2002
that contain sample design
variables in masked form. The initial release of the 2000-2002 public-use files includes 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 have been 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. NAMCS,
