The article, “Evaluation of Between-County Disparities in Premature Mortality Due to Stroke in the US,” examines the differences in premature stroke mortality in terms of between-county disparity in the US, for deaths that occurred out of the stroke unit, county-level mortality was largely associated with demographic composition (31.6%) and health care and environmental features (25.8%). For in-hospital death, 29.8% of county-level mortality was associated with population health and 28.7% was associated with demographic composition.

These findings suggest the need to tailor strategies to address premature stroke in the county-level context before implementing interventions for the neediest counties.
