Some health insurance recode variables classify insurance types differently than other U.S. Census Bureau surveys do. In SIPP, people are classified as having private insurance (RPRIMTH) if they reported having a private insurance plan, other coverage obtained through a person in the household, or reported a Medigap plan. Meanwhile, the CPS ASEC defines having private coverage as those who reported a private plan or TRICARE military coverage.
In SIPP, people are classified as having public coverage (RPUBMTH) if they report Medicaid, Medicare (Part B or D), any type of military plan, or any public or government provided coverage. CPS ASEC defines public coverage as having Medicaid, Medicare, or CHAMPVA/VA care.
