A population-based study was conducted to quantify the relative risks of injury mortality across subpopulations in the Northwest Territories. The major causes of injury mortality in both regional centres & remote communities were motor vehicles, drowning, & suicide. 45% of injury deaths occurred in remote communities where the prevention of injuries is more difficult. Recommendations include: prevention programs in regional centres be extended to remote communities; and, prevention efforts in remote communities target Aboriginal peoples. (7 refs)
