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. There are five types of records in this core survey, each in a separate data file. The variables in the Household File (Part 1) include type of living quarters, size of family, region, and type of sampling area. The Person File (Part 2) includes sex, age, race, marital status, veteran status, and education. These variables are found in the Condition, Doctor Visit, and Hospital Episode Files as well. The Person File also supplies data on height, weight, bed days, doctor visits, hospital stays, years at residence, and region variables. The Condition (Part 3), Doctor Visit (Part 4), and Hospital Episode (Part 5) Files contain information on each reported acute or chronic condition, doctor visit, or hospitalization, respectively. A sixth, seventh, and eighth file have been provided. The Health Insurance Supplement File (Part6) contains information on the type of health insurance held by each respondent from the Person file. Parts 7-8 comprise the Supplement on Aging (SOA) Files divided into Condition and Person Public Use Files respectively, and contain data on a subset of the NHIS population, those aged 55 and over. These files contain the same Condition and Person variables as Parts 2-3 but are supplemented by questions pertaining specifically to the subpopulation of older respondents. These additional variables cover family relationships and support, community and social support, occupation and retirement, nursing home stays, help with care, health opinions, and other health-related and social information about middle-aged and older people.

In preparing the data files 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.



Sample age distribution for Part 2, the Person file, is: 45-54 (10,561), 55-64 (9,852), 64-74 (7,344), and 75+ (4,550). For Part 6, the Supplement on Aging--Person file, sample age distribution is: 55-64 (4,651), 65-74 (7,093), and 75+ (4,404).

The data contain dashes (-).

Per agreement with NCHS, ICPSR distributes the data files and text of the technical documentation for this collection as prepared by NCHS.

A multistage probability sample is used for the HIS. Respondents to the Supplement on Aging are all the members of households included in the 1984 HIS who were 65 years of age or older at the time of the interview, and a one-half sample of those between the ages of 55 and 64.

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

2000-02-21 The codebook has been converted to a PDF file.

1987-05-19 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created online analysis version with question text.

Detailed information regarding the use of weights is located within the documentation.


  • 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.
