Living HHS Open Data Plan

The Living HHS Open Data Plan is a multi-year, evolving blueprint (version 1.0, published July 2025) for implementing the OPEN Government Data Act (Evidence Act, Title II) across HHS. It embraces an "open by default" approach to data sharing, ensuring transparency, responsiveness, and accountability in delivering on HHS’s mission. Designed to adapt over time, this plan from the HHS Chief Data Officer with concurrence from all HHS Divisions fosters partnerships, public engagement, and data-driven collaboration by making HHS data more accessible, usable, and valuable for the public. Versions: Version 1.1, published 12/22/25 Version 1.0, published 07/30/25
