MIGMET23ERR
Coverage error in MIGMET23 variables

Description

MIGMET23ERR reports, for each metropolitan area identified by MIGMET23, the level of spatial mismatch error between the identified area and the actual 2023 metropolitan statistical area (MSA).

The code assignment protocol of MIGMET23 yields errors of omission (residents of a MSA who are not identified as residents) and errors of commission (non-residents who are identified as residents). As an index of mismatch, IPUMS uses the sum of percent omission error (the portion of an MSA's population residing in excluded Migration PUMAs) and percent commission error (the portion of the population in associated Migration PUMAs that did not reside in the MSA).

For each reported MIGMET23 code, MIGMET23ERR identifies the level of the sum of errors.

The MIGMET23 variables report no code for MSAs where the sum of match errors is 15% or more. Researchers may use MIGMET23ERR to impose a more restrictive error limit if desired.

To compute match errors, IPUMS uses 2020 populations for 2012-2031 ACS and PRCS samples.

For detailed information about 2023 MSA delineations and their correspondence with Migration PUMAs, see the 2023 Migration Areas geographic resource page.
