The variable PAOC was designed to indicate for women 16 years and over, the presence of an own child in the household (a son or daughter under age 18 and never married). An error was found in the programming of this variable that resulted in the inconsistent identification of women in subfamilies having a child, producing an underestimate of the numbers of women with own children usually in the 1 percent to 2 percent range for each of the states.

This problem affected the PUMS file and several estimates in Detailed Table B23003. As a result, the PUMS files for 2005 and 2006 will be re-issued with the corrected PAOC variable, and the B23003 tables for 2005 and 2006 have been removed from the AFF along with necessary changes to ACS Summary File. These tables will not be re-issued, but the programming will be corrected for future releases. Please note that the PUMS files and data products for the years prior to 2005 will not be corrected.

PAOC is also a small part of the editing procedure used to create the employment status recode (ESR). A review concluded that this error affected ESR and some other variables
