National Health Interview Survey, 1975: Health Maintenance Organization (HMO) Supplement (ICPSR 9744)
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 kinds of health services people receive. The 1975 Health Maintenance Organization (HMO) Supplement provides variables from the core Person File (see HEALTH INTERVIEW SURVEY, 1975 [ICPSR 7672]) 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 questions about whether the respondent belonged to a medical plan or plans, type of medical plan or plans, how long respondent had been a member, whether the respondent saw doctors outside the plan, reasons for seeing other doctors, and place where respondent obtained care.
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.

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 statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
