2019 NHIS Redesign

For the first time in over 20 years the National Health Interview Survey (NHIS) redesigned its questionnaires in 2019. Information that were previously collected for all family members are now only collected for sample adults and/or sample children. The interviewer completes a household rostering interview to collect basic demographic information of all people who usually live or stay in the household. The redesigned sample adult and sample child questionnaire structures consist of four components: the annual core, rotating core, sponsored content (sustaining and periodic), and emerging topics. 2019 data and documents are now available from NHIS site. To learn more about NHIS redesign, please review this report below.
