Corrections and Enhancements to the 2003, 2004, 2005, and 2006 ACS 1-Year Public Use Microdata Sample (PUMS) Files and the 2005-2007 ACS 3-Year PUMS Files

January 25, 2012

The 2003, 2004, 2005, and 2006 ACS 1-year PUMS and the 2005-2007 3-year PUMS files were revised in November 2010 to correct an error in the AGE variable and to make a number of other smaller improvements. The table below is a complete list of changes made to the revised files. The original version of this note posted in November 2010 did not describe the complete list of changes made to the revised files.

PUMS Files	Description of corrections	Impacted Variables
All Samples	The age variable was corrected for persons age 65 and up.	The revised files apply a modified age perturbation edit. This is the same revision that was made to the 2006 ACS 1-year PUMS files, described in Errata Note 50. For more details on how the corrections were made, see the User Note titled, "The Correction and Re-release of the 2003, 2004, and 2005 ACS 1-year Public Use Microdata Sample (PUMS) Files and the 2005-2007 3-year PUMS Files."
2005 1-year 2006 1-year	Topcodes were raised for several income variables.	The re-released files applied higher topcodes to several income variables, including INTP, OIP, RETP, SEMP, and WAGP. The additional detail in the new files resulted in a small number of changes to variables that are built from component income variables, including FINCP, GRPIP, HINCP, OCPIP, PERNP, POVPIP, and PINCP. The changes affect less than 2 percent of the cases in each file.
2003 1-year 2004 1-year 2005 1-year 2006 1-year	Topcodes were raised for several housing characteristic variables.	The re-released files applied higher topcodes to housing variables including CONP in all years and including MHP and RNTP in 2006. The 2006 changes in RNTP also caused a small number of changes in GRNTP and GRPIP.
2003 1-year	Errors in the family and household income variables were corrected.	For approximately 15,000 cases, the personal income variables from the population file were not being summed correctly in the creation of the family and household income variables, FINCP and HINCP. The re-released files corrected this problem. The changes to HINCP also resulted in a smaller number of changes in the GRPIP variable.
2003 1-year 2004 1-year 2005 1-year 2006 1-year 2005-2007 3-year	Variables indicating period of military service were made consistent with new age values.	The revised AGE values in the re-released files created inconsistencies with variables indicating period of military service. As a result, some values were changed for the variables MIL, MLPA, MLPB, MLPG, MLPH, MLPI, MLPJ, MPLK, and VPS. These changes affected fewer than 1,000 cases in each dataset.
2003 1-year 2004 1-year 2005 1-year 2006 1-year	A previously documented error in the Selected Monthly Owner Costs variable was corrected.	Errata 41 instructed users how to fix a problem with the SMOCP variable in the original PUMS releases. The error was corrected in the re-released files. Users do not need to apply any additional fixes. The SMOCP changes also caused changes in OCPIP.
2005 1-year 2006 1-year	A previously documented error in the variable indicating presence and age of own children was corrected.	Errata 40 described an error with the PAOC variable in the 2005 and 2006 1-year PUMS. The error was corrected in the re-released files.
2006 1-year	An error in the variable documenting previous state or country of residence was corrected.	MIGSP values of 168 (undocumented) in the original PUMS release were changed to values of 169 "(Other Europe, not specified") in the re-release.
2005 1-year	Errors in variables indicating Census Bureau division and region were corrected for all cases in Puerto Rico.	In Puerto Rico, DIVISION values were changed from 7 (indicating the West South Central division) to 0 (indicating that PR is not part of a Census Bureau division). REGION values were changed from 3 (indicating the Southern Region) to 9 (indicating that PR is not in a Census Bureau region).
2004 1-year	An error in the variable documenting when the household moved into the house or apartment was corrected.	Code used to construct MV in the 2004 1-year PUMS was edited to be consistent with code used in later years. As a result, MV values for about 42,000 households were changed to be one category higher or lower than they were in the original PUMS release.
2005-2007 3-year	Inflation adjustment variables were corrected.	The factor to adjust income and earnings dollar amounts for inflation (ADJINC) was corrected for the 2007 cases on the 2005-2007 files. The factor to adjust housing dollar amounts for inflation (ADJHSG) was moved from the person-level files to the housing unit-level files, which made it consistent with the documentation.
2005-2007 3-year	Occupation codes were updated to be consistent for all years.	Occupational codes in the SOCP variable were edited so that 2005 cases were coded in the same way as 2006 and 2007 cases. Specifically, SOCP values of 119190 were changed to 1191XX, values of 1311XX were changed to 131XXX, and values of 231011 were changed to 2310XX. OCCP values were altered only for cases from 2005.

Previous notes about this error were posted November 18, 2010 (see below).

Age Adjustments in the 2003, 2004, and 2005 ACS 1-year Public Use Microdata Sample (PUMS) Files and the 2005-2007 ACS 3-year PUMS Files

The 2003, 2004, and 2005 ACS 1-year PUMS and the 2005-2007 3-year PUMS files have been revised by applying a modified age perturbation edit. This is the same revision that was made to the 2006 ACS 1-year PUMS files that is described in Errata Note #50. For more details on how the corrections were made, see the User Note titled “The Correction and Re-release of the 2003, 2004, and 2005 ACS 1-year Public Use Microdata Sample (PUMS) Files and the 2005-2007 3-year PUMS Files.”

Several other minor corrections were made to the 2005-2007 3-year PUMS files. The factor to adjust housing dollar amounts for inflation (ADJHSG) has been moved from the person-level files to the housing unit-level files, which will make it consistent with the documentation. The factor to adjust income and earnings dollar amounts for inflation (ADJINC) has been corrected for the 2007 cases on the 2005-2007 files. The occupation code (SOCP) for the 2005 cases on the person-level file have been updated to be consistent with the new occupation codes used for the 2006 and 2007 cases.
