<unk>  is an effort to prevent or reduce the severity of bodily<unk> es caused by external mechanisms, such as accidents, before they occur.<unk>  is a component of safety and public health, and its goal is to improve the health of the population by preventing<unk> es and hence improving quality of life. Among laypersons, the term "accidental<unk> " is often used. However, "accidental" implies the causes of<unk> es are random in nature. Researchers prefer the term "unintentional<unk> " to refer to<unk> es that are nonvolitional but often preventable. Data from the U.S. Centers for Disease Control show that unintentional<unk> es are a significant public health concern: they are by far the leading cause of death from ages 1 through 44. During these years, unintentional<unk> es account for more deaths than the next three leading causes of death combined. Unintentional<unk> es also account for the top ten sources of nonfatal emergency room visits for persons up to age 9 and nine of the top ten sources of nonfatal emergency room visits for persons over the age of 9.<unk>  strategies cover a variety of approaches, many of which are classified as falling under the "3 Es" of<unk> : education, engineering modifications, and enforcement/enactment of policies. Some organizations and researchers have variously proposed the addition of equity, empowerment, emotion, empathy, evaluation, and economic incentives to this list.
