Data users who developed estimates using the DataFerrett version of the 2010-2012 ACS 3-Year PUMS files from February 6, 2014 to June 2, 2014 will want to rerun critical estimates. These files were erroneously compiled due to a coding error when bringing in the records to DataFerrett. This error did not affect the PUMS CSV files and SAS datasets which can be downloaded directly from the PUMS FTP web site. The DataFerrett version of the 2010-2012 ACS 3-Year PUMS files were corrected and re-released on June 2, 2014.
