Description

HIURULE is constructed by the State Health Access Data Assistance Center (SHADAC) at the University of Minnesota. HIURULE is an indicator of the assignment rule used to assign each individual to a "health insurance unit" (HIU). HIUs are uniquely identified by HIUID.

Health insurance coverage, whether through an employer or a public program, is often based on family relationships. An individual with access to employer-sponsored coverage may be able to cover his or her spouse and children through that policy. Public coverage often considers family ties in determining program eligibility, especially for children and families. Many analysts and researchers have adopted the use of a "health insurance unit" (HIU) in studying insurance coverage so as to focus on those individuals who would likely be considered a "family unit" in determining eligibility for either private or public coverage.

The SHADAC HIU aims to capture the key components of both "public" and "private" HIUs in a single measure. The HIU definition is implemented with the following assignment rules:

• Married couples, regardless of age, with no children of their own living with them are assigned to their own HIU;
• Single or married parents, regardless of age, along with their eligible children;
• Eligible children with no parent in their household, but who are related to the household reference person, are placed in the first HIU in the household; are assigned to an HIU;
• Eligible children with no parent in the household and who are not related to the household reference person are placed in their own HIU.

Eligible children are children under age 19 who are not married and have no children of their own. The HIU is constructed using the following IPUMS variables: SERIAL, PERNUM, RELATE, AGE, SEX, MARST, MOMLOC, POPLOC, SPLOC, and NCHILD.

Code 50 (Point single adults to self) is defined as single, spouse absent, separated, divorced, widowed and no own children in household.

Code 60 (Point related singleton children to first HIU reference person in household) is defined as no parents in household, but related to the reference person.

Comparability

In 2017, SHADAC introduced code to identify same-sex couples. As a result, the category "Point married female, with spouse present, to spouse" was changed to "Point married person, with spouse present, to spouse." Moreover, the categories "Point eligible child to father, if present" and "Point eligible child to mother, if present and father absent" were collapsed to "Point eligible child to parent, if present." To maintain the detail of earlier coding, IPUMS-USA expanded the HIURULE variable.

In 2020, SHADAC revised the health insurance unit (HIU) to update who is included in the definition of "family" based on changes to public and private insurance programs and changes to federal survey relationship codes. As a result, the category "Point eligible child to parent, if present" was expanded to reflect these changes in the 2019 1-year ACS file. More information about the development of the SHADAC HIU and the 2020 revision can be found in the 2020 Update of SHADAC's Health Insurance Unit brief.
