County Health Rankings & Roadmaps Open Source Project

Open Source Project

The County Health Rankings & Roadmaps Open Source Project aims to preserve, update, and extend CHR&R data and resources.

Since 2008, CHR&R has helped communities understand the factors that shape health and equity. This project continues that mission by advancing transparency and data democratization, ensuring that CHR&R data, methods, and tools remain accessible after funding for the program ends in December 2026.

This project has been developed and curated by current and former CHR&R team members.
