National Health Interview Survey, 1974: Medical Care Supplement (ICPSR 9797)
The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the types of health services people receive. The 1974 Medical Care Supplement File provides variables from the core Person File (see HEALTH INTERVIEW SURVEY, 1974 [ICPSR 8339]) including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this Medical Care Supplement (Part 1) include items on type of doctor visits (private vs. group practice), place of care, number of doctor visits in the last 12 months, type of doctor usually seen, payment source for doctor bills, problems getting care in the past year, and type of medical services received in the last twelve months.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

- Created online analysis version with question text.
Restrictions: In preparing the data tape(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than for statistical analysis and reporting.
