For all conditions, PIDX is a within-Dwelling Unit (DU) person identifier assigned in sampling or by the computer-assisted personal interviewing (CAPI) instrument on the condition record. PIDX must be combined with DUIDX and PANELX to uniquely identify persons across all MEPS data. IPUMS MEPS offers the constructed variable MEPSIDX, created by concatenating the values of PANELX, DUIDX, and PIDX.
Please see the user note for more information on the relationship between Dwelling Units, families, Reporting Units, and persons.
