CALIFORNIA SUICIDE DECLINE, 1970-1990

From 1970 to 1990 California experienced a 32% decline in suicide, which was particularly pronounced among women, non-whites, the young, and urban dwellers. Suicide declines of over 50% were recorded in San Francisco and Los Angeles, and large decreases occurred in other coastal counties. Additionally, California was the only one of 51 states to show a consistent decline in teenage and young-adult suicide (accompanied by an 88% decrease in teenage drug and other poisoning deaths). Initial investigation of death certification, accident and homicide trends, economic measures, and prevention efforts did not produce an explanation for a suicide decrease of California's magnitude. However, the state does display anomalous trends in certain social measures (reduced divorce, rising non-White population, and rising homicide) that point to multifactorial hypotheses including demographic changes and changed attitudes toward violence. Review of the accuracy of past suicide certification procedures nationally is also indicated.
