Using official suicide statistics, this study examined suicide rates in Canada from 1956-1981 as a function of age, gender, & geographical region. The analysis revealed that, for both genders, the risk of suicide among 15-24-year-olds increased at a faster rate than in any other age group. Male & female age-standardized suicide rates demonstrated an overall increase during the study period. The trend for males was one of continuous increase, whereas female rates reached a maximum in 1976 & then decreased. Regional differences in suicide rates were also apparent. Several possible explanations for these findings are presented. (35 refs.)
