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 (12-month recall), respectively.
These data are freely available.
This dataset is maintained and distributed by the National Archive of Computerized Data on Aging (NACDA), the aging program within ICPSR. NACDA is sponsored by the National Institute on Aging (NIA) at the National Institutes of Heath (NIH).

Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: Civilian, noninstitutionalized population of the 50 states and the District of Columbia.
Data Types: survey data
Data Collection Notes:
Per agreement with NCHS, ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS. The age distribution for the Person file is: ages 0-44 (N=83,883), ages 45-54 (N=12,362), ages 55-64 (N=10,940), ages 65-74 (N=9,286), ages 75+ (N=5,839), black respondents (N=18,713), and Hispanic respondents (N=9,582). The data contain ampersands (&), dashes (-), and blank codes.
Sample: Starting in 1985, the NHIS multistage probability sampling from 1,924 geographically defined Primary Sampling Units (PSUs) 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 201 PSUs were selected, including two from each nonself-representing stratum. Black persons were oversampled. Four independent representative samples were drawn which may be used in any combination.
