evidence: The chart below shows the likelihood, or odds, of dying as a result of a specific type of accident. The odds of dying over a one-year period are based on the U.S. population as a whole, not on participants in any particular activity or on how dangerous that activity may be. For example, more people are killed in auto accidents than in motorcycle accidents or airplane crashes, not because riding a motorcycle or traveling in an airplane is more or less dangerous, but because far more people travel by car.
