About the United States Census Bureau Data Repository

The United States Census Bureau Data Repository preserves and disseminates survey instruments, specifications, data dictionaries, codebooks, and other materials provided by the U.S. Census Bureau. ICPSR, the host of this data repository, has also listed additional Census-related data collections from its larger holdings.

The repository helps fulfill key recommendations made by the 2017 "Report of the Commission on Evidence-Based Policymaking." Specifically, the repository improves transparency by establishing a "searchable inventory, through which the public can learn about the data that government collects." The robust metadata also enables "researchers inside and outside government...[to] be better able to identify which data are needed and useful for answering policy questions, conducting program evaluations, and reducing inefficient and unnecessary data requests."
