Comparability
This variable is largely comparable over time. Some differences in universe must be accounted for to properly compare this variable across samples. See the Universe tab for details.
In addition to changes in universe, 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.
