For people age 44 and under, the leading cause of death is accidental injury. This may come as a surprise to many Arizona residents. According to 2016 statistics, however, 61,749 Americans in the aforementioned age group died due to unintended incidents of various types. This amounts to nearly twice as many as from cancer and heart disease combined. The Centers for Disease Control and Prevention noted two primary types of accidental deaths: motor vehicle crashes and unintentional poisonings.
