County Health Rankings & Roadmaps Open-source Project

Welcome to the County Health Rankings & Roadmaps Open-source Project

The County Health Rankings & Roadmaps (CHR&R) Open-source Project aims to preserve, update, and extend CHR&R. Since 2008, CHR&R has helped communities understand the factors that shape health and equity. The program advocates for a new understanding of data and evidence and develops methods that can challenge assumptions, explore possibilities, and build community power for health and equity. This project ensures that CHR&R data, methods, and tools remain accessible after CHR&R’s funding from the Robert Wood Johnson Foundation ends in December 2026.
Whether you’re reproducing CHR&R methods, refreshing them for future years, or creating something entirely new, you’re invited to learn and build with us. Let’s keep this important public data alive together!
The resources below have been developed and curated by current and former CHR&R team members.
