Comparability
Prior to 2019, this variable is completely comparable over time. Beginning in 2019, age values were bottom coded to 18 or younger (code = 18) and questionnaire changes were introduced. 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.
