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 variables in the Household Record file (Part 1) include type of living quarters, size of family, number of families in the household, if there is a telephone, number of unrelated individuals, and region. The Person Record file (Part 2) includes information on sex, age, race, marital status, Hispanic origin, education, veteran status, family income, family size, major activities, health status, activity limits, employment status, and industry and occupation. These variables are also found in the Condition, Doctor Visit, and Hospital Record files. The Person Record also supplies data on height, weight, bed days, doctor visits, hospital stays, years at residence, and region variables. The Condition Record file (Part 3) contains information for each reported health condition, with specifics on injury and accident reports. The Doctor Visit Record file (Part 4) documents doctor visits within the time period and identifies acute or chronic conditions. The Hospital Record file (Part 5) provides information on medical conditions, hospital episodes, type of service, type of hospital ownership, date of admission and discharge, number of nights in hospital, and operations performed.
These data are freely available.

(2) The codebook and the coding manual are provided as Portable Document Format (PDF) files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided through the ICPSR Website on the Internet. (3) The Field Representative's Manual is available only in hardcopy form upon request from ICPSR.
Sample: The NHIS uses a stratified multistage probability design. The sample for the NHIS is redesigned every decade using population data from the most recent decennial census. A redesigned sample was implemented in 1995. This new design includes a greater number of primary sampling units (PSUs) (from 198 in 1994 to 358), and a more complicated nonresponse adjustment based on household screening and oversampling of Black and Hispanic persons, for more reliable estimates of these groups.
