Reformulation of the Family Life-Cycle Concept: Implications for Residential Mobility

The conventional concept of linear progression through a traditional life cycle underlies much of social science theory. The utility of retaining the traditional life-cycle framework has declined rapidly as patterns of family and nonfamily structure and behavior have become more diversified. A more comprehensive framework which encompasses these new household types is suggested. The utility of this expanded life-cycle model is explored, with particular reference to single-headed family households and primary households.
