Trump 2.0 has deleted or altered nearly 400 US datasets, endangering public health, education and more

# Why This Matters The deletion or alteration of nearly 400 federal datasets represents a fundamental threat to evidence-based policymaking across multiple sectors that directly affect American lives. Public health officials, researchers, and educators rely on comprehensive federal data to track disease outbreaks, identify health disparities, allocate school resources, and design interventions—removing or modifying this information means hospitals may lack critical epidemiological trends, schools cannot accurately assess achievement gaps, and public health agencies cannot respond effectively to emerging threats. The suppression of environmental and climate data similarly prevents communities from understanding local pollution levels or making informed decisions about industrial projects. Beyond immediate operational consequences, this data removal erodes democratic accountability by obscuring the government's own performance metrics, making it impossible for the public, Congress, and independent researchers to evaluate whether federal programs are actually working as intended.
