2010 Migration PUMA Definitions
The map below displays the boundaries and codes for migration Public Use Microdata Areas (MIGPUMAs), as identified by MIGPUMA1 in ACS and PRCS samples. 2005-2011 ACS samples use the 2000 MIGPUMA definitions while 2012 and later ACS samples use the 2010 definitions. Each MIGPUMA corresponds exactly to one or more PUMAs.
The 2000 MIGPUMAs resource page provides the relationships between 2000 PUMAs and MIGPUMAs. The relationships between 2010 PUMAs and MIGPUMAs 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 PUMAs of Migration. Gray lines represent County boundaries. Clicking on an area will highlight and describe the 2010 Place of Work PUMA of Migration, 2000 PUMA of Migration, 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.
