Abstract
This is an updating of an earlier publication on tribal differences in Native American suicidal behavior. Similarities among these studies are noted, including data sources, the concentration of suicide among the young, intratribal group heterogeneity with respect to suicide, suicide methods employed, and alcohol involvement. Most investigations have relied heavily on single official sources for their data. The implications of obtaining figures from official agencies are explored, particularly with respect to Native American tribes and reservations. Neglected areas of study are noted along with the need for further investigation to facilitate prevention programs.
