Description

For medication-round records, MEPSIDM is a variable that uniquely identifies respondents across MEPS panels. It is created by combining PANELM, DUIDM, and PIDM. IPUMS MEPS staff created MEPSIDM for the 1996-2017 samples to provide a single, universal linking key for MEPS persons. Beginning in 2018, AHRQ modified the identifiers DUIDM and DUPERSIDM (which combines DUIDM with PIDM) on the original MEPS data files to append information about PANELM to the first two columns. This update makes DUPERSIDM identical to MEPSIDM in the IPUMS MEPS extract system for 2018-forward.
