Description

PWCOUNTY identifies the county (or county equivalent) where the respondent worked if the respondent's workplace was in an identifiable county.

PWCOUNTY uses the Federal Information Processing Standard (FIPS) coding scheme, as is used by COUNTYFIP. FIPS county codes are state-dependent, so PWCOUNTY must be combined with state codes (see PWSTATE2) to distinguish counties located in different states.

The source PUMS files do not directly identify place-of-work counties. IPUMS instead identifies counties, where possible, from Place-of-Work PUMAs (PWPUMA00).

PWCOUNTY identifies a county if and only if:

• it was coterminous with a single Place-of-Work PUMA; or

• it contained multiple Place-of-Work PUMAs, none of which extended into other counties.

For a listing of the counties that PWCOUNTY identifies, see the "MIG-PW" sheets in this Excel document:

• Counties Identified in IPUMS USA Samples

PWCOUNTY is a 3-digit numeric variable that identifies the county (or county equivalent) where the respondent worked using the Federal Information Processing Standard (FIPS) coding scheme.

PWCOUNTY-Specific Variable Code
000 = County not identifiable from public-use data

Comparability

This variable is comparable across years, but county boundaries and Place-of-Work PUMA definitions change over time. PWCOUNTY identification is based on the census information corresponding to the Place-of-Work PUMA (PWPUMA00) definitions used in the source samples, as follows:
2022-forward ACS/PRCS: 2020 Place-of-Work PUMAs
2010 census and 2012-2021 ACS/PRCS: 2010 Place-of-Work PUMAs
2000 census and 2005-2011 ACS/PRCS: 2000 Place-of-Work PUMAs
