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