War and Suicide*

The suicide rate generally appears to decline during the time of war. The traditional psychodynamic explanation that this decrease results from the legitimization of outward aggression is questioned. World War II evidence from both occupied and neutral countries, together with fluctuations of the suicide rates among the Scandinavian countries, are better understood as reflecting the social conditions of wartime, rather than the presence of actual fighting. These data, and others, point to the hypothesis that the decreased suicide rate during wartime is tied to the greater social integration–increased patriotism, ease of promotions, greater sense of purpose, and so forth–resulting from a state of war.
