Overview

U.S. Constitution overlays a cityscape

The U.S. Government maintains reliable, standardized data from a variety of federal agencies in short to determine congressional representation, allocate resources to states, and develop effective policies to support the daily life of Americans.

Since the start of this administration, it has become increasingly common for government data sets, ones that were previously publicly available, to be removed. Since the beginning of 2025, librarians, archivists, scientists, researchers, and independent agencies have been preserving at-risk public information. These links connect you to essential data for continuing your research, though they represent only some of the many organizations and individuals responding to the current data crisis.
