Responses from a sample of 400 older persons were used to determine the relative importance of various family members (spouse, children, siblings, other relatives) and friends in the confidant and companion networks of later life. Significant differences exist among older persons (based on gender, marital status, and availability of children) in the salience of these ties as confidants and companions. There are also major differences in the configuration of the confidant vs companion networks. These variations are discussed in the context of the hierarchical-compensation, task specificity, and functional specificity of relationships models of support. The findings demonstrate that a distinction regarding availability of kin must be made among those who never had a particular kin tie (e.g., the childless and single), those who have lost a previous tie (e.g., the widowed), and those whose tie lives far away.
