The National Health Interview Survey (NHIS) is a continuous survey that has collected health data using personal interviews since 1957. The unit response rate historically has been high, above 90% for the first forty years of the survey. In the past decade, the unit response rate has declined to approximately 80%. We discuss changes in the methodology for unit nonresponse adjustment over the history of the survey, with a focus on potential future changes that employ auxiliary data.
