Description

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

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

PIDF is a 3-digit numeric variable.
