Attempted suicide is not uncommon among adolescents. The ratio of attempted suicides to actual suicides is in the magnitude of 100:1. This is in contrast to quoted figures of 5:1. While actual suicides are more common in the male and in the white, attempted suicides are more frequent in the female, the Puerto Rican, and in the low socioeconomic groups. Another pertinent finding was the high percentage of suicides among adolescents from unstable and disorganized homes. Early identification of the high-risk group is essential. Intensive "after care" for all such individuals should be made mandatory. A prevention center is of value in the control of suicides. The accumulation of epidemiological data is a prerequisite to a clearer identification of the problem and in formulation of sound countermeasures.
