Methods of suicide by age: sex and race differences among the young and old

The elderly have the highest suicide rate in the United States. In partial explanation of this finding, a common statement in the suicide literature is that older persons tend to use more drastic and effective methods of suicide. However, little, if any, data have been presented in defense of this explanation. In order to investigate the validity of this contention, annual official statistics for specific methods of suicide (firearms, hanging, poisons) by age for different sex and racial groups (whites, blacks, nonwhites excluding black) were examined from 1960 to 1978. Comparisons among the age-sex-race groups, along with trends over time and differences in the methods employed, were noted. For white males, blacks of both sexes, and nonwhites excluding black females, the findings confirmed the use of more violent methods by the elderly than by the young in terms of the proportion of suicides by firearms and/or hanging. Less support and, in fact, opposite results for method-related age differences were obtained for white females and nonwhites excluding black males. Another general finding was an increase in the use of firearms for most of the groups studied. The need for data for specific groups within the nonwhite category excluding blacks is apparent both from the available literature and from the present findings. Possible explanations and implications of the observed results are discussed.
