Codes and Frequencies
For sample adults and sample children (and, prior to 2019, all persons), HINONE reports whether the person did not currently have any health insurance coverage. Prior to 2019, interviewers handed persons a card with categories of insurance types listed on it, as well as the category of "no coverage of any type." For 2019 forward interviewers read off each option listed. HINONE indicates the person chose this latter category.
Users are strongly encouraged to review the user notes Insurance Data Collection for changes in the response categories listed on the card.
Interviewers asked, "What kind of health insurance or health care coverage do you have?" Respondents selected the appropriate response from a card (2000-2018) or from options read by the interviewer (2019 forward) listing various types of insurance coverage:
- Private health insurance (2004 forward)
- Private health insurance plan from employer or workplace (1997-2003)
- Private health insurance plan purchased directly (1997-2003)
- Private health insurance plan through a state or local government program or community program (1998-2003)
- Medicare (1997 forward)
- Medi-Gap (1997 forward)
- Medicaid (1997 forward)
- CHIP (Children's Health Insurance Program) (1999 forward)
- Military Health Care/VA (1997-2003)
- Military Health Care (CHAMPUS/TRICARE/CHAMP-VA) (1997-2018)
- Military related health care: TRICARE (CHAMPUS)/VA health care/CHAMP-VA (2019 forward)
- Indian Health Service (1997 forward)
- State-sponsored health plan (1997 forward)
- Other government program (1997 forward)
- Single Service Plan (e.g., dental, vision, prescriptions) (1999-2018)
- No coverage of any type (2000 forward)
Respondents could pick more than one type of insurance and interviewers were instructed to mark all that applied.
Changes to the list of health insurance coverage types should not affect the meaning of "no coverage of any type". Other than changes to the types of coverage included and substantial questionnaire changes introduced in 2019 that may affect comparability with earlier years, there are no comparability issues.
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.
