Abstract: The basic 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. Household variables in this data collection include type of living quarters, size of family, number of families in household, and geographic region. Person variables include sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The Condition, Doctor Visit, and Hospital files contain information on each reported condition, two-week doctor visit, or hospitalization (twelve-month recall), respectively. Respondents for the Functional Limitations Supplement were persons age 65 and older. Questions concerned degree of difficulty in performing activities of daily living. For the Longest Job Worked Supplement, respondents were persons age 25 or older who had worked. Information obtained in this supplement determines the effects of a person's job on his or her health. Respondents for the Vitamin/Mineral Intake Supplement were sampled from those age 2-6 and those 18 or older. Proxies for the children and the adults themselves were asked questions to determine individual consumption of these nutrients and their effects on health. The Health and Dental Insurance Supplements include all the respondents, and have questions on Medicare and other types of health insurance coverage, reasons for visits to the dentist, use of fluorides, and other oral health practices.

SOURCE: personal interviews

UNIVERSE: Civilian, noninstitutionalized population of the United States and the District of Columbia from 1,900 geographically defined Primary Sampling Units (PSUs).

SAMPLE: Starting in 1985, the NHIS multi-stage probability sampling design incorporates several major changes that facilitate linkages with other National Center for Health Statistics surveys, improve precision of estimates, and reduce costs. Starting with an all-area frame, a reduced number of 198 PSUs were selected, including two from each non-self representing stratum. Black persons were oversampled. Four independent representative samples were drawn which may be used in any combination.

NOTE: The data contain ampersands (&), dashes (-), and blank codes. There are 837 Black respondents of all ages in the Functional Limitations Supplement. The age distribution for this supplement is: N=4,401 ages 65-74, and N=2,791 ages 75+. There are 10,053 Black respondents of all ages in the Person File and the Health and Dental Insurance Supplements. The age distribution for these files is: N=48,998 ages <6-54, N=5,862 ages 55-64, N=4,401 ages 65-74, N=2,791 ages 75+. There are 2,206 Black respondents of all ages in the Vitamin/Mineral Intake Supplement and the age distribution for this supplement is: N=12,302 ages <6-54, N=2,006 ages 55-64, N=1,865 ages 54-74, N=1,233 ages 75+. There are 5,225 Black respondents of all ages in the Longest Job Worked Supplement and the age distribution is: N=24,863 ages <6-54, N=5,862 ages 55-64, N=4,401 ages 65-74, N=2,701 ages 75+.
