National Health Interview Survey, 1975: Health Maintenance Organization (HMO) Supplement (ICPSR 9744)
Principal Investigator(s): United States Department of Health and Human Services. Centers for Disease Control and Prevention. National Center for Health Statistics
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.
These data are available to the general public.
