The variables identifying health insurance coverage units are not being released on the public use files. These variables were created in the 2014 SIPP Panel to be comparable to those used in the 2008 Panel. These variables attempt to group together individuals sharing a health insurance policy. Although useful for internal data processing, the variables were not intuitive to use and also had high imputation rates.  The variables not released include: EHIUNT1, EHIUNT2, EMLUNT and EMDUNT.
