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