Norway has a suicide rate one half to one third that of other Scandinavian countries. The author summarizes the 6 year study of the Nordic Planning Group on Research in Suicidology set up in 1976 to investigate this difference. After examining suicide registration, they concluded that the possibility for error was not signicantly higher in Norway. In comparing social integration in Denmark & Norway, they found that the lower suicide rate in Norway mirrored better social integration. (GW)
