			  March 28, 2002

-----------------------------------------------------------------
2000 Core Files:

The 2000 National Health Interview Survey (NHIS) includes the 
same core files as the 1999 NHIS, with the following exceptions:

-- instead of separate Injury Episode and Poison Episode files, 
there is now a combined Injury/Poison Episode file 

-- the Injury Verbatim file becomes the Injury/Poison Verbatim 
file

Beginning in data year 2000, NHIS implemented hot deck 
imputation of the race and ethnicity variables; these new 
variables' names have been changed and all end in _I.  The race 
and ethnicity changes are discussed in greater detail in 
Appendix II of the Survey Description Document.  

2000 Supplemental Information:

Added to the end of the 2000 Sample Adult file is the Cancer 
Control Module.  Topics from that supplemental module are:

	Hispanic Acculturation
	Diet and Nutrition
	Physical Activity
	Tobacco
	Cancer Screening
	Genetic Testing
	Family History
