In this article, we present a new method for measuring residential arrangements of children following parental divorce. We discuss the limitations of conventional methods for measuring postdivorce residential situations of children, but our principal objective is to present a promising alternative, the residential calendar. We evaluate its utility with data coming from the Leuven Adolescents and Families project, collected from a sample of 878 Flemish adolescents, who have experienced a parental breakup. Several substantive and methodological arguments and supporting analyses illustrate the potential value of the residential calendar for collecting policy-relevant data on the consequences of divorce.
