Health Interview Survey, 1971

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
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, 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
variables in the Household File (Part 2) 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 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 added, along with the five core files. The Person Supplement File (Part 6) provides information on health conditions, hearing quality, doctor visits, and hospital stay information.
