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.

This problem affects PUMS and may possibly affect other data products. It is currently under review and any updates will be posted as soon as they are available.
