The purpose of the County Health Rankings is to compare counties within states. We discourage comparisons between states for several reasons:
- The County Health Rankings are not intended to be a national report that finds the 10 or 15 least healthy counties in the nation and focuses only on that. The Rankings are intended to provide a tool for communities in each state as a call to identify opportunities for improvement
- We focus on state-specific county rankings, and we do not provide any county rankings across state boundaries.
- A few of the measures that we use are state-specific and make comparisons across state boundaries difficult.
