When Aggression is Turned Inward (IN: Death and Violence on the Reservation. Homicide, Family Violence, and Suicide in American Indian Populations, by R Bachman)
The etiology of American Indian suicide was examined through a reservation-county-level analysis. It was found that economic deprivation has a significant & positive impact on the suicide rate. As unemployment, dropout & poverty rates increased within a reservation community, so did the suicide rate. When communities provide little opportunity for economic self-sufficiency, frustrations appear to be manifested in acts of violence directed toward the self (suicide) or against others (homicide).
