2010 Migration PUMA Definitions
The 2010 definitions of Migration Public Use Microdata Areas (Migration PUMAs) are used in 2012 and later ACS and PRCS samples to identify where respondents moved from. See the MIGPUMA1 variable description for more information.
The 2005-2011 ACS and PRCS samples use 2000 Migration PUMA definitions. In Multi-Year ACS/PRCS files, PUMA boundaries depend on the year the respondent was interviewed. (See MULTYEAR.) For example, in the 2010-2012 3-year ACS sample, responses from 2010 and 2011 use 2000 definitions of Migration PUMAs, while responses from 2012 use 2010 definitions.
