Relevant Population CharacteristicsStroke is more common in older compared to younger persons. Although strokes occur in all age groups, those 65 and older are most likely to experience stroke. In fact, for people over age 55, the incidence of stroke more than doubles in each successive decade. Women account for almost 60% of US stroke deaths. The incidence of stroke also varies by race and ethnicity. Compared with whites, blacks have a 1.3 times greater rate of nonfatal stroke, a 1.8 times greater rate of fatal stroke. Stroke is a leading cause of long-term disability with women having greater disability than men.^3^[[br]]
