Over the last 20 years, suicide rates have grown across most demographic groups in the United States, making the sociological study of suicide as imperative now as it was in Durkheim's day. For the most part, however, sociologists study suicide solely using Durkheim's analytic strategy. The following article recovers a text on suicide long since forgotten by sociology. Divided into three parts, the article begins first by revisiting Ruth Cavan's social disorganizational theory of suicide, eventually culminating in a formalization of her theory. Second, the article brings contemporary social scientific ideas to bear on her theory to modify and extend its empirical utility. Third, the article considers the implications this theoretical exercise has for an increasingly vibrant and creative sociology of suicide.
