An International Comparison of Adolescent and Young Adult Mortality.

This paper analyzes mortality rates for 3 of the main causes of deaths between the ages of 15 and 34 (motor vehicle injuries, homicide, and suicide) from 1950 to 1996, and across 26 countries. Average sex ratios and age patterns and the trends in age- and sex-standardized mortality rates are analyzed for each cause. Overall, youth violent mortality levels have been remarkably stable since the 1950s. As mortality due to other causes has receded, the contribution of these three causes has increased from 25 to 40 percent between the 1950s and the mid-1970s, and has remained above 40 percent since. Last, a principal component analysis is performed to summarize the variance in age-, sex-, and cause-specific rates over time and across countries. This summary representation of international differences displays regional clusters and emphasizes the "outlying" position of the United States among industrialized nations.
