Performed a cohort analysis of the 4315 suicide deaths registered in Alberta. Age, gender, & year of death were available in all but 2 instances. Analyses were done for males & females separately and combined. Suicide rates increased directly with age, regardless of gender for each cohort observed. Once a cohort entered the 15-19 yr old age range with a high rate of suicide, the rate for that cohort remained consistently high as it aged.
