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. For the 1964-1965 survey, the sample plan included about 134,000 persons from approximately 42,000 households.

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 1964-1965, the survey included sections on medications (prescription and nonprescription), tobacco use, and a comprehensive supplemental questionnaire on diabetes.
