Survey round number, round record


For all persons, ROUNDRD reports the round in which the data were collected. MEPS interviews persons five times, once per round. Analysts may wish to combine ROUNDRD with MEPSIDRD, to uniquely identify round-level records.

Persons with data for both calendar years in which their Panel participated have two Round 3 records. This is because, although the Round 3 interview occurs in the second calendar year, the Round 3 reference period spans both calendar years. Therefore, the individual's Round 3 record is written to both the first calendar year data file and the second calendar year data file. For more information on the relationship between calendar year, panel, and round data, please see the IPUMS MEPS Panel Design Documentation.
