Why is there so much difference in the health of residents in one county compared to other counties in the same state? In this report, the County Health Rankings & Roadmaps program explores how wide gaps are throughout Alaska and what is driving those differences. This information can help Alaska state leaders as they identify ways for everyone to have a fair chance to lead the healthiest life possible. Specifically, this document can help state leaders understand: 1. What health gaps are and why they matter 2. The size and nature of the health gaps among boroughs/census areas within Alaska 3. What factors are influencing the health of residents, and 4. What state and local communities can do to address health gaps.
