National Health Interview Survey, 1979: Eye Care Supplement (ICPSR 9221)
The basic purpose of the Health Interview Survey (HIS) 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 Eye Care Supplement file provides variables from the core Person file (see NATIONAL HEALTH INTERVIEW SURVEY, 1979 [ICPSR 8049]) including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this Eye Care Supplement include information on eye care in the past 12 months, kind of doctor/specialist, place of visit, and date of last visit.
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.

Scope of Study
Geographic Coverage: United States
The supplements to the Health Interview Surveys may be used independently, since they incorporate the person file data for this subset. The National Center for Health Statistics now refers to these supplements as current health topics. The data contain ampersands (&), dashes (-), and blank codes.
These data files contain weights, which must be used in any analysis.
Per agreement with the National Center for Health Statistics (NCHS), ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS.
Weight: These data contain multiple weight variables for each part. Users should refer to the User Guide for further information regarding the weights and their derivation. Additionally, users may need to weight the data prior to analysis.
Extent of Processing: 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.
Restrictions: Individual identifiers have been removed from the microdata tapes available from the National Center for Health Statistics. Nevertheless, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), data collected by the National Center for Health Statistics may not be used for any purpose other than for statistical reporting. ICPSR recommends to users that individual elementary unit data contained in this collection be used solely for statistical research.
