Suicide and homicide in the United States: an epidemiologic study of violent death, population changes, and the potential for prediction

Abstract

The authors found significant positive correlations between the suicide and homicide rates for 15-24-year-olds and the proportion of 15-24-year-olds in the U.S. population from 1933 to 1982. Significant negative correlations were found for most adult age groups (35-64 years). Since future numbers of adolescents and adults can be estimated on the basis of current population data for children and preadolescents, the epidemiologic patterns for suicide and homicide may be predictable for certain age groups. However, methodologic problems are inherent in using national mortality and population data, and many years are necessary to evaluate such epidemiologic propositions.
