Final answer:
Young adults are most likely to die from accidents and injuries, with causes such as car crashes and homicides being common in this age group.
Step-by-step explanation:
Young adults (ages 15-24) are most likely to die from accidents and injuries. During early adulthood, common causes of death include homicides, car crashes, rather than from chronic diseases such as cardiovascular disease, which typically affect older adults. Homicides, car crashes, are the most common causes of death in this age group. This is due to factors such as risky behavior, lack of driving experience, and mental health issues. According to the Centers for Disease Control and Prevention (CDC), head and traumatic brain injuries are a major cause of immediate death and disability, with many of these injuries resulting from accidents like automobile and motorcycle crashes, which are particularly prevalent in this age group.
