For sample adults with at least two private health insurance plans, HIP2WHO indicates the policyholder of the second private health insurance plan held. Prior to 2019, for persons with at least two private health insurance plans, HIP2WHO reports if the second plan is in the name of the person, someone else in the family, or a person not in the household.

Additional information about the identity of the policyholder is available for sample adults in HIP2RELPOLICY.


This variable is completely comparable between 1997 and 2018. Beginning in 2019, three changes affect comparability with earlier years. First, there were changes in the response categories and the universe: starting in 2019, additional detail about the identity of the health insurance plan policyholder was dropped and HIP2WHO simply indicates whether the person is the policyholder or someone else is the policyholder. Second, the universe also changed in 2019, from all persons with private health insurance to sample children and sample adults with private health insurance. Third, questionnaire design changes introduced in 2019 limit 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.
