National Health Interview Survey, 1993 (ICPSR 6534)
Principal Investigator(s): United States Department of Health and Human Services. National Center for Health Statistics
The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and the distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Household Record variables in this data collection include type of living quarters, size of family, number of families in the household, and geographic location. Person Record variables include sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limitations on activity. The Condition Record file contains information for each reported health condition, with specifics on injury and accident reports. The Doctor Visit Record file documents doctor visits within the time period and identifies acute or chronic conditions. The Hospital Episode Record file contains all recalled accounts of hospitalizations in the 12-month period.
These data are freely available.

Subject Terms: chronic disabilities, chronic illnesses, disabilities, doctor visits, families, health, health care, health care services, health policy, health problems, hospitalization, household composition, households, illness
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 1993 National Health Interview Survey closely resembles the 1992 version, but race categories were expanded considerably for the Person, Condition, Doctor Visit, and Hospital records.
Sample: The NHIS uses a multistage sample designed to represent the civilian, noninstitutionalized population of the United States. The data collected in the NHIS are obtained through a complex design involving both clustering and stratification such that each person included has a known nonzero probability of selection.
Restrictions: In preparing the data tape(s) 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.
