In 1999, the mortality rate for children and adolescents aged 10–14 years for deaths from motor vehicle traffic injury (4.5 per 100,000) was about four times higher than the rate for deaths for suicide and homicide (both at 1.2).
From 1999 to 2014, the death rate for motor vehicle traffic injury declined 58%, to 1.9 in 2014 (384 deaths).
From 1999 to 2007, the death rate for suicide fluctuated and then doubled from 2007 (0.9) to 2014 (2.1, 425 deaths).
The death rate for homicide gradually declined to 0.8 in 2014. In 2013 and 2014, the differences between death rates for motor vehicle traffic injury and suicide were not statistically significant.
