Description
HINOTCOV is a recoded variable created by the IPUMS NHIS staff that indicates, for sample adults and sample children (and, prior to 2019, all persons), whether the individual had any general health insurance coverage. For 1976-1996, IPUMS NHIS staff identified uninsured persons as those without any private insurance, or without public health insurance coverage through Medicaid, Medicare, military health care. Persons covered only by the Indian Health Service (1993-1996) are coded as having no health insurance. For 1997 forward, uninsured persons were identified as those who answered "no" to the question, "{Are you/Is anyone} covered by any kind of health insurance or some other kind of health care plan?" See the survey questions section below for more details.
For most years, HINOTCOV refers to a current lack of insurance coverage; for 1990 to 1996, the variable refers coverage status during the previous month.
Methods of Determining Lack of Insurance
The process used to ascertain the lack of insurance coverage reported in HINOTCOV changed over time. A brief description is provided below, while further information on the data collection process appears in the User Note on Changes in Insurance Data Collection.
[show more]For 1976 to 1999, lack of health insurance was ascertained indirectly. In other words, having no coverage was inferred from responses to a series of questions on various forms of coverage. Interviewers asked about coverage through Medicare, Medicaid or other public assistance programs, military health care, and private insurance. Persons not covered by any of these types of insurance were coded as having no health insurance.
For 1980 to 1996, persons who received Aid to Families with Dependent Children (AFDC) or Supplemental Security Income (SSI) were assumed to have health insurance coverage, since they were eligible for health care coverage (i.e., Medicaid) through these programs.
For 2000 forward, HINOTCOV reflects a response of "no coverage of any kind" to a direct question about what type of insurance the person had.
The specific questions used to determine coverage status changed over time.
[show more]These questions are as follows:
1997 forward:

Comparability
HINOTCOV is largely comparable before 2019, though the sources of information used to create this variable and the reference period (currently or in the previous month) were not the same in every year. Substantial questionnaire changes introduced in 2019 may limit comparability with earlier years.
Variation in the measurement of Medicaid coverage status may affect the accuracy of levels of coverage over time. See HIPUBCOVE for more detail on this point.
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.
