President Donald Trump's second term saw a significant decline in federal data collection across various sectors, according to a report released Dec. 31, 2025. The administration's actions, driven by ideological opposition to data, a desire to conceal unfavorable trends, and budget cuts, have undermined data collection related to the environment, public health, employment, demographics, and weather, the report stated.

The reduction in data collection has far-reaching consequences, potentially hindering scientific advancements, obscuring the economic landscape, and impeding the ability of officials to address critical health issues, the report indicated. Umair Irfan, one of the report's authors, noted that "with less robust and accurate data, advances in science will slow down."

The administration's approach has been characterized by a reliance on anecdotal evidence and personal intuition, rather than empirical data, according to critics. This "no data, just vibes" approach, as described in the report, has raised concerns about the integrity of government decision-making and the ability to address complex challenges effectively.

Budget cuts have significantly impacted agencies' ability to maintain data collection efforts. Deep job losses within these agencies have further exacerbated the problem, leaving them understaffed and unable to adequately track and analyze vital information.

The long-term effects of these data collection rollbacks remain to be seen. However, experts warn that the lack of reliable data could have detrimental consequences for policymaking, scientific research, and public understanding of critical issues facing the nation. The report suggests that restoring data collection efforts will be crucial for ensuring evidence-based decision-making and addressing future challenges effectively.
