Summary 

Since 1957, the National Health Interview Survey (NHIS) has been a primary source of information on the health of the population of the United States. The NHIS is a cross-sectional household interview survey that is fielded continuously throughout the year. Budget restraints reduced the interviewing period for the 1970 survey by 7 weeks, which reduced the sample to approximately 37,000 households containing about 116,000 persons.

A core questionnaire collected data on topics such as acute conditions, injuries, chronic conditions, days of disability, limitation of activity, hospitalization, and demographic information such as housing, family composition, income, etc. For 1970, the survey included sections on tobacco use, x-rays, and health insurance.

A supplemental questionnaire on health care costs was mailed to the sample for the fourth quarter. This supplemental questionnaire collected data on health insurance premiums and out-of-pocket expenditures.
