Person number, round record


[ PRELIMINARY VARIABLE: Variable description may change once we confirm the universe and assess the comparability of this variable over time. ]

For all persons, PIDRD is a within-Dwelling Unit (DU) person identifier assigned in sampling or by the computer-assisted personal interviewing (CAPI) instrument on the round record. PIDRD must be combined with DUIDRD and PANELRD to uniquely identify persons across all MEPS data. IPUMS MEPS offers the constructed variable MEPSIDRD, created by concatenating the values of DUIDRD, PIDRD, and PANELRD.

Please see the user note for more information on the relationship between Dwelling Units, families, Reporting Units, and persons.
