Description
PWMET13ERR reports, for each metropolitan area identified by PWMET13, the level of spatial mismatch error between the identified area and the actual 2013 metropolitan statistical area (MSA).
The code assignment protocol of PWMET13 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 PWMET13 code, PWMET13ERR identifies the level of the sum of errors.
PWMET13 reports no code for MSAs where the sum of match errors is 15% or more. Researchers may use PWMET13ERR to impose a more restrictive error limit if desired.
To compute match errors, IPUMS uses 2020 populations for 2022-forward ACS and PRCS samples and 2010 populations for 2005-2021 ACS and PRCS samples. For samples that use 2000 Place-of-Work PUMA definitions (2000 samples and ACS and PRCS samples through 2011), IPUMS estimates the populations of the areas of intersection between 2000 Place-of-Work PUMAs and 2013 MSAs by summing the populations of census blocks that had their geographic center in each area.
In multi-year ACS/PRCS samples that span different Place-of-Work PUMA definitions, this variable is based on whichever Place-of-Work PUMA definition is associated with the respondent's survey year (as given by MULTYEAR). This occurs only in the 2022 5-year samples and in multi-year samples that include both 2011 and 2012 survey years. For more information about how Place-of-Work PUMA definitions vary within multi-year samples, see the PWPUMA00 variable description.
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 more detailed information about relationships between Place-of-Work PUMAs and MSAs, IPUMS provides these tables (in Excel spreadsheets):
2000 5% sample:
2005-2011 ACS and PRCS samples: 2012-2021 ACS and PRCS samples:- 2010 Migration PUMAs are identical to 2010 Place of Work PUMAs, so these reference files pertain to both MIGMET131 and PWMET13 for 2012-2021 samples
- 2020 Migration PUMAs are identical to 2020 Place of Work PUMAs, so these reference files pertain to both MIGMET131 and PWMET13 for 2022 and later samples
