Description
PWMET23ERR reports, for each metropolitan area identified by PWMET23, the level of spatial mismatch error between the identified area and the actual 2023 metropolitan statistical area (MSA).
The code assignment protocol of PWMET23 yields errors of omission (workers in a metro area who are not identified as workers there) and errors of commission (respondents identified as working in a metro area who worked elsewhere).
As an index of mismatch, IPUMS uses the sum of percent population omission error (the portion of an MSA's population residing in excluded Place-of-Work PUMAs) and percent population commission error (the portion of the population in associated Place-of-Work PUMAs that did not reside in the MSA).
For each reported PWMET23 code, PWMET23ERR identifies the level of the sum of errors.
PWMET23 reports no code for MSAs where the sum of match errors is 15% or more. Researchers may use PWMET23ERR to impose a more restrictive error limit if desired.
To compute match errors, IPUMS uses 2020 populations for 2022-2031 ACS and PRCS samples and 2010 populations are used for 2012-2021 ACS and PRCS samples.
The actual omission and commission errors for workers of a metropolitan area may differ substantially from the errors based on residents. IPUMS uses resident counts to compute mismatches because worker counts are not available for small areas, as needed to compute counts for all intersections between Place-of-Work PUMAs and MSAs.
For detailed information about 2023 MSA delineations and their correspondence with Place-of-Work PUMAs, see the 2023 Place-of-Work Areas geographic resource page.
