Nearly 80 percent of young people in the United States who die are killed by injuries, and more than half of these injuries are unintentional, such as those sustained in car crashes, falls or fires, according to a new report.

Researchers looked at all people ages 1 to 30 in the United States who died in 2010, and found that 79 percent of deaths in that group were from injuries; while 20 percent were from chronic diseases such as heart disease or cancer, and 1 percent were due to infections, the report said.

Of the deaths among young people that were due to injuries, about 60 percent were a result of unintentional injuries, while 20 percent were due to suicide, and another 20 percent to homicide.
