Among adults, 21% rode bicycles within the past 30 days and 29% of them always wore helmets. Among children, 61% rode bicycles within the past 30 days and 42% of them always wore helmets.
Children were more likely to always wear helmets (90%) when their adult respondents always wore helmets. Children who lived in states with a child bicycle helmet law wore helmets more than those without a law. Cyclists should wear helmets because they are highly effective at reducing the risk for head injuries and death.
