Suicide and homicide rates in Canada and the United States

Suicide and homicide rates by age were analyzed for Canada and the United States, indicating that suicide is higher in Canada and that homicide is higher in the United States. Results indicated a positive association between homicide and suicide rates in the United States but these two rates of death were not significantly associated in Canada. Holinger (1987) had associated the relative size of the cohort to the rates of suicide and homicide in young people in the United States. The more current data in both countries did not support Holinger's results. Using the measure devised by Easterlin (1980) and Ahlburg and Schapiro (1984)-that is, the proportion of youths aged 15-24 relative to adults aged 25-64-the correlation between the size of the youth cohort and the suicide rate of youths aged 15-24 was negative. It is concluded that the two patterns in these two countries may be explained from a historical perspective.
