youth suicide rate in canada

Suicide has accounted for about 2% of annual deaths in Canada since the late 1970s. Eighty percent of all suicides reported in 1991 involved men. The male:female ratio for suicide risk was 3.8:1. In both males and females, the greatest increase between 1960 and 1991 occurred in the 15-to-19-year age group, with a four-and-a-half-fold increase for males, and a three-fold increase for females.

Suicide rates in the Canadian Native population are more than twice the sex-specific rates, and three times the age- specific rates of non-Native Canadians (56.3 for Native males and 11.8 for Native females). Suicide rates in federal and provincial prisons vary from 8 to 47 times rates in the general population. People with family member who committed suicide are nine times more likely than others to kill themselves. The mentally ill (those with affective disorder, schizophrenia, neurosis, personality disorder or organic brain syndrome) and people with drug and alcohol problems are at greater risk (by a factor of 2.4 to 23 times) than the general population
