The age at first marriage in the U.S. has consistently increased, while the age at cohabitation has stalled. These trends present an opportunity for serial cohabitation (multiple cohabiting unions). The authors argue that serial cohabitation must be measured among those at risk, who have ended their first cohabiting union. Drawing on data from the National Survey of Family Growth Cycle 6 (2002), and continuous 2006–2013 interview cycles, the authors find that serial cohabitation is increasing among women at risk. Millennials, born 1980–1984, had 50% higher rates of cohabiting twice or more after dissolving their first cohabitation. This increase, however, is not driven by the composition of Millennials at risk for serial cohabitation. This work demonstrates the importance of clearly defining who is at risk for serial cohabitation when reporting estimates, as well as continuing to examine how the associations between sociodemographic characteristics and serial cohabitation may shift over time.

Objective: The objective of this study is to determine whether income‐pooling strategies differ between married and cohabiting individuals without children, only biological children, or any stepchildren. Background: Americans are forming families in new ways via cohabitation and stepfamilies, which may have implications for resource pooling. Although a majority of married and cohabiting couples pool their incomes, little is known about the role of children in couple's income‐pooling behaviors. Method: The authors use recently collected, nationally representative data from the Families and Relationships Study (n = 4,362). Controlling for sociodemographic, household, and relationship characteristics, the authors use logistic regression to predict the odds of income pooling among married and cohabiting individuals without children, only biological children, or any stepchildren. Results: The likelihood of income pooling remained similar among cohabitors regardless of the configuration of children in the household. Among married families, however, the likelihood of income pooling differed by the presence of resident stepchildren. Married families with resident stepchildren had a lower probability of pooling their income when compared with married families with only resident biological children. Conclusion: The ways economic resources are shared differs across family types. The findings from this study are consistent with an incomplete institutionalization perspective and demonstrate that individuals in cohabiting‐couple families and married‐couple families with resident stepchildren are less likely to pool their incomes.

The elevated risk of repeat unintended fertility does not seem to be due to mothers' initial postpartum contraceptive behavior. Whether mothers with unintended births use contraceptives less consistently, discontinue use sooner or switch methods more often than those with intended births remains to be seen.

goods and assets to which a family has access. Research has linked family wealth with various domains of child well-being, and these accumulated resources may have both direct and indirect benefits for children (Elliott, Destin,

Objective:To determine whether recent birth cohorts of women experienced more union dissolution during young adulthood (ages 18-25) than previous birth cohorts. Background: The union formation and dissolution patterns of young adult women in the United States have changed dramatically during the past 25 years. As a result, this life stage is demographically dense as women experience a bulk of relationship experiences, including coresidential unions and dissolution. Method: The author uses data on women's marital and cohabiting dissolutions between the ages of 18 and 25 from the National Survey of Family Growth 1995, 2002, and continuous surveys from 2006to 2010. The sample is nationally representative. The author uses generalized ordinal logistic regression to examine the likelihood of dissolution during young adulthood across birth cohorts. Results: Women born between 1985 and 1989 experience more union dissolutions during young adulthood than women born between 1960 and 1979. However, the shift in cohabitation behavior accounts for this instability. Conclusion: Women's relationship formation experiences in young adulthood are characterized by nonmarital relationships (cohabitation)
