Principal Investigator(s):


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 Family Medical Expenses Supplement provides variables from the 1975 core Person File (see HEALTH INTERVIEW SURVEY, 1975 [ICPSR 7672]) and variables from the 1976 core Person File (see HEALTH INTERVIEW SURVEY, 1976 [ICPSR 8340]) 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 amounts paid for personal, family, and outside family dental bills, doctor bills, hospital bills, optical bills, prescription medicine, health insurance, and other medical expenses. Other questions include total personal, family, and outside family medical expenses, including and excluding health insurance, and the sex and race of the family head.
