2010 Place of Work PUMA Definitions

Back to Geographic Tools

The map below displays the boundaries and codes for Place of Work Public Use Microdata Areas (PWPUMAs), as identified by PWPUMA00 in ACS and PRCS samples. 2005-2011 ACS samples use the 2000 PWPUMA definitions while 2012 and later ACS samples use the 2010 definitions. Each PWPUMA corresponds exactly to one or more PUMAs.

The 2000 PWPUMAs resource page provides the relationships between 2000 PUMAs and PWPUMAs. The relationships between 2010 PUMAs and PWPUMAs are given in this Excel spreadsheet: 2010 PUMA-MIGPUMA-PWPUMA Relationships. (2010 migration PUMAs and place of work PUMAs are identical, so their relationships to 2010 PUMAs are the same.)

In Multi-Year ACS/PRCS files, PUMA boundaries depend on the original year the respondent was interviewed (see MULTYEAR). For example in the 2010-2012 3-year ACS sample, respondents from 2010 and 2011 correspond to the Census 2000 based PUMAs, while respondents from 2012 correspond to the Census 2010 based PUMAs.

Zooming into an area of interest on the map below will show both the 2010 (in blue) and 2000 (in orange) based Place of Work PUMAs. Gray lines represent County boundaries. Clicking on an area will highlight and describe the 2010 Place of Work PUMA, 2000 Place of Work PUMA, and County boundaries associated with the selected area. You can select which boundaries you want to view using the Layers menu at the top of the map. There is also a larger map containing the same information.
