A total annual average of 4,358 AAD (5%) and 249,727 YPLL (10%) involved those under age 21 years from 2006 through 2010 (data not shown). Similar to the findings for adults, about 78% of the AAD and 76% of the YPLL in those younger than 21 involved males. However, in contrast to the findings for adults, all of the top 3 causes of death for those under age 21 years —specifically, motor-vehicle traffic crashes, homicide, and suicide —were acute conditions. In fact, motor-vehicle traffic crashes alone accounted for 36% of the total AAD for those under age 21 years.
