title: Version 1

description: The purpose of the Health Interview Survey 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 the core survey, each in a separate data file. The variables in the Household File (Part 1) include type of living quarters, size of family, number of families in the household, presence of a telephone, number of unrelated individuals, and region. The Person 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 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 File (Part 3) contains information for each reported health condition, with specifics on injury and accident reports. The Hospital Episode File (Part 4) 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. The Doctor Visit File (Part 5) documents doctor visits within the time period and identifies acute or chronic conditions. A sixth file has been provided. The Child Health Supplement File (Part 6) provides detailed data on child health and development. This supplement offers information on age of child, sex, birth-date, physical and social development, family relationships, prenatal care, hospitalization and illness, behavior, schooling, and seat-belt usage.

Corrections to Part 2, Person File, are included where the original data on age, sex, or date of birth have been found to be in error.
These data files contain weights that must be used in any analysis.
Per agreement with the National Center for Health Statistics (NCHS), ICPSR distributes the data files and text of the technical documentation for this collection as prepared by NCHS.
The original column locations for variables C_1704, C_2015, and C_2016 in the Child Health Supplement File (Part 6) have been modified; the column locations provided by the NCHS were incorrect. Variables C_2015 and C_2016 have been renamed to accurately reflect the proper column locations. C_2015 is now named C_2016, and C_2016 is now named C_2017.
