Comparability
While the basic meaning of this variable is completely comparable over time, major questionnaire changes introduced in 2019 and changes in the universe may affect comparability with earlier years. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
