title: National Health Interview Surveys, 1986-1994: Multiple Cause of Death, Dates of Death, 1986-1995
title: Version 1

description: This data collection supplies date and cause of death data
 for sample persons included in the National Health Interview Surveys
 (NHIS) for the years 1986 through 1994. Beginning with survey year
 1986, linkage information was collected on NHIS respondents aged 18
 and older to allow for matching with other data systems such as the
 National Death Index (NDI). The Multiple Cause of Death (MCD) data
 files contain information on those persons with scores high enough to
 be considered deceased or scores high enough that they may be included
 in an analysis as deceased. The Ineligible Cases data files contain
 person IDs of those NHIS participants under the age of 18 as well as
 those with insufficient information to permit linkage with the
 NDI. These cases should be excluded from the NHIS survey data files
 prior to analysis. Linkage of the NHIS respondents with the NDI
 provides a longitudinal component to the NHIS that allows for the
 ascertainment of vital status. The addition of vital status permits
 the use of NHIS data to estimate survival, mortality, and life
 expectancy while using the richness of the NHIS questionnaires, both
 core and supplements, as covariates. These data files must be used in
 conjunction with the basic NHIS data files (1986 [ICPSR 8976], 1987
 [ICPSR 9195], 1988 [ICPSR 9412], 1989 [ICPSR 9583], 1990 [ICPSR 9839],
 1991 [ICPSR 6049], 1992 [ICPSR 6343], 1993 [ICPSR 6534], 1994 [ICPSR
 6724]). Variables included in the MCD files cover year of interview,
 quarter, household number, person number, month and year of death,
 vital status, and causes of death. The Ineligible Cases files contain
 a person ID that matches columns 3-16 on the NHIS public use data
files.

description: (1) Per agreement with NCHS, ICPSR distributes the
 data file(s) and text of the technical documentation for this
 collection as prepared by NCHS. (2) The linkage used with these files
 employs a different methodology than previous linkages and replaces
 all previous NHIS-NDI linked files (ICPSR 6475-6479). (3) The
 documentation is provided as a Portable Document Format (PDF)
 file. The PDF file format was developed by Adobe Systems Incorporated
 and can be accessed using PDF reader software, such as the Adobe
 Acrobat Reader. Information on how to obtain a copy of the Acrobat
Reader is provided through the ICPSR Website on the Internet.
