Answer

The incidence of stroke varies with age, sex, ethnicity, and socioeconomic status. For example, American Heart Association (AHA) researchers found that rates of intracerebral hemorrhage are higher in Mexican Americans, Latin Americans, blacks, Native Americans, Japanese people, and Chinese people than they are in whites. [5]

Flaherty et al found that excess risk of intracranial hemorrhage in African Americans is largely attributable to higher hemorrhage rates in young and middle-aged persons, particularly for deep cerebral and brainstem locations. Hypertension is the predominant risk factor. [24]
