There were 44 states in which the percentage of unspecified stroke among all strokes was \u226550 and 20 states in which the percentage was \u226555%. The percentage was lowest in the District of Columbia (46%) and highest in Oklahoma (64%). The state variation in the proportion of unspecified stroke decreased with age of the deceased.
