The U.S. Department of Health and Human Services (HHS) has released its Living HHS Open Data Plan alongside a newly revamped HealthData.gov website, marking a major step forward in the agency’s push for transparency, innovation, and data-informed governance.

These initiatives, under the leadership of the HHS Chief Data Officer (CDO) Dr. Kristen Honey, support the OPEN Government Data Act and advance the broader objectives of the Foundations for Evidence-Based Policymaking Act (Evidence Act), signed by President Trump in January 2019.

“Open Data will serve as the foundation for radical transparency, innovation, accountability, and public trust. HHS Open Data is not just about numbers; it’s about empowering people, fostering trust, and driving real-world impact,” Dr. Honey stated in a press release. 

“Since the Trump Administration began, HHS has more than tripled the number of datasets on HealthData.gov—from approximately 3,000 in January 2025 to over 10,000 today. Using data, AI, and regulatory reform, HHS will increase public transparency and leverage information to Make America Healthy Again,” Deputy Secretary Jim O’Neill, added.

The updated platform introduces key public assets, including the HHS Open Data Plan (v1.0), Metadata Standard, and Data Inventory, creating a more unified and interoperable data environment.

HHS is also adopting a culture of “open by default,” inviting public collaboration via its GitHub repository. The plan will be updated quarterly with input from stakeholders to ensure it remains dynamic, transparent, and impactful.
