Codes and Frequencies
For sample adults and sample children (and, prior to 2019, all persons) with a state-sponsored health plan (HISTATEE), STATEXCHG reports if the person's health insurance was obtained through a state or federal insurance marketplace (e.g., Healthcare.gov or a state Health Insurance Marketplace).
New questions were added to the Health Insurance section of the NHIS Family core in 2014 to obtain details about whether plans (both private and public) were obtained through Healthcare.gov or the person's state Health Insurance Marketplace, whether there is an enrollment fee or premium (public plans only), and whether the premium is based on income (expanded to include public plans). For more information on these questions, please refer to MCAIDXCHG.
Questionnaire changes introduced in 2019 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.
- 2014-2018: All persons with a state-sponsored plan.
