Marital and Cohabiting Union Dissolution in Middle and Later Life.

This study examined the timing and risk factors for subsequent union disruption among individuals who were in a marital or cohabiting union at age 45, focusing particularly on the role of prior union history and children. Using retrospective data on union histories from the 2007 Canadian General Social Survey ( n = 17,194), the results of life-table analysis revealed that individuals in cohabiting relationships faced a greater risk of union disruption in middle or later life than those who were married. Cox proportional hazard models showed that both union biography (duration, remarriage/repartnership) and family biography (children born inside/outside union, child age) influenced union dissolution through separation or divorce, but their impact differed depending on union type and gender. These findings suggest that when it comes to marriage and cohabitation, the middle and later years of life are neither a clear continuation nor a complete departure from earlier patterns.
