Thanks Penelope for the reminder! The good news with the ACS 2012 is that the Census-2010-based PUMAs (Public Use Microdata Areas) are a "standard summary level" in American Factfinder. If you're using American Factfinder (AFF), just select the "all geographic types" (instead of "most requested geographic types") in the geographic selection window of AFF. The 3-year (2010-2012) and 5-year (2008-2012) ACS data are scheduled for release over the next several months, with the 5-year PUMS (I'll assume with the newer PUMAs) to be released in January 2014. http://www.census.gov/acs/www/data_documentation/2012_release_schedule/ 10/24/13 -- 3 year ACS data; and the 1-year PUMS 12/5/13 -- 5 year ACS data; and the 3-year PUMS 1/23/14 - 5-year PUMS Lots of new interesting data to plumb.
