title: National Health Interview Survey, 1970

description: &lt;p&gt;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 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. The Health Insurance file (Part 6) includes information on education level, family income, hospital visits and length of stay, and also data on medical coverage, hospital coverage, medicare coverage, and doctor visit coverage. The Medical Care Cost file (Part 7) includes information on hospital bill expenses, doctor and dental bill expenses, optical bill expenses, and total personal and family expenses. The X-Ray file (Part 8) includes information on x-ray records, doctor visits, height, weight, and total medical x-ray visits. (Source: downloaded from ICPSR 7/13/10)&lt;/p&gt;

description: collection_notes: The sampling plan of the survey follows a multistage probability design, which permits a continuous sampling of the civilian, noninstitutionalized population of the United States. The sample is designed in such a way that the sample
of households interviewed each week is representative of the target population and that weekly samples are additive over time. This feature of the design permits both continuous measurement of characteristics of samples and more detailed analysis of less common characteristics and smaller categories of health-related items. The continuous collection has administrative and operational advantages as well as technical assets since it permits fieldwork to be handled with an experienced, stable staff.
