Announcing CHR&R’s 2025 Data Viz Challenge

County Health Rankings & Roadmaps (CHR&R) is inviting original visualizations using CHR&R data to communicate the structural determinants of health, or the laws, policies, and power structures that drive health outcomes. We want to see how you use CHR&R (and other public data) to tell stories that make the forces that shape health visible.

We believe that working together amplifies impact. In this open call for data visualizations, we’re honoring the power of our connectedness — the reality that your eyes and experience create a unique perspective on the health story we share. Recognizing how our fates are intertwined is central to transforming the structural forces that shape opportunities for health.

Who should submit:

Students, researchers, analysts, public health professionals, advocates and community members are encouraged to participate. Submissions are welcome from individuals and teams. Multiple entries are allowed through August 1, 2025. Winners will be announced August 8, 2025.

What to submit:

• A static or interactive visualization which utilizes at least one CHR&R measure. Examples include maps, plots, dashboards and infographics. Any U.S. geography and timeframe is acceptable.
• A description between 250–500 words that explains:
  • which structural determinant(s) are visualized;
  • why these determinants are important to community health; and,
  • what inspired your choice of measures and visual format.
• Selected submissions will be recognized on the CHR&R website and highlighted in our newsletter and social media. Winners may be invited to collaborate with CHR&R experts on future data features or presentations.

Submissions will be judged by CHR&R staff based on their:

• relevance to the structural determinants of health
• clarity of message
• design and technical execution
• creativity

Where to find data:

• Most recent year’s data are available in our GitHub repository: https://github.com/County-Health-Rankings-and-Roadmaps/chrr_measure_calcs/tree/main/complete_datasets
