Data Release Rules

Because American Community Survey (ACS) data are so far-reaching in their coverage, users may sometimes encounter tables or estimates that are suppressed or not available. The purpose of this brief is twofold. First, we describe the ACS data products released each year and the rules that are applied to determine whether ACS tabulated data products and estimates will be published. Second, we provide guidance and strategies to data users about how to proceed in exploring other options when the ACS data they seek are not available.
