Public health data transparency research
Health Data Transparency Index
Compare how U.S. states publish, organize, and document public health data. The index brings state-level scoring, evidence links, confidence notes, and methodology context into one searchable view for researchers, public-sector teams, analysts, and policy stakeholders.
Find a state profile
Search by state name or abbreviation to open a transparency profile with score, tier, evidence, and validation details.
Compare transparency signals
Review price transparency, public health reporting, open data access, quality reporting, insurance oversight, and machine-readable data.
Use the rankings responsibly
Treat scores as a research benchmark for public evidence availability, not as a judgment of health outcomes or agency performance.
