National Health Interview Survey, 1978: Health Insurance Supplement (ICPSR 9227)
Published: Jan 6, 2011
The basic purpose of the Health Interview Survey (HIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. The 1978 Health Insurance Supplement provides variables from the core Person File (see HEALTH INTERVIEW SURVEY, 1978 [ICPSR 8044])including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this supplement include information on type of health care coverage (Medicare, private, AFDC or Medicaid, or VA plans), reasons for no health care insurance, what services health care plan covers, how plan was obtained, use of insurance, and blood donations.
Individual identifiers have been removed from the microdata tapes available from the National Center for Health Statistics. Nevertheless, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), data collected by the National Center for Health Statistics may not be used for any purpose other than for statistical reporting. ICPSR recommends to users that individual elementary unit data contained in this collection be used solely for statistical research.
