In 2015, the U.S. life expectancy decreased for the first time since 1993. In addition to a significant increase in overall deaths from heart disease, some researchers noted an increase in mortality among young people, specifically from preventable causes such as drug overdose, homicide, and suicide.
People aged 65 and older accounted for approximately 73% of all deaths in the United States in 2015. Deaths among older Americans were caused mostly by heart disease, cancer, chronic lower respiratory disease, and stroke.
While 18 to 34 year olds accounted for just 3% of all fatalities, young people are 35% more likely to die of an accidental poisoning than the population as a whole, 42% more likely to die in a car accident, and more than twice as likely to die of a firearm-related homicide.
To determine the leading causes of death for young people, 24/7 Wall St. reviewed mortality data from the Centers for Disease Control and Prevention for Americans aged 18 to 34 years old. In 2015, 17 causes of death each accounted for more than 500 deaths in the age cohort.
