Shifts in Higher-Order Unions and Stepfamilies among Currently Cohabiting and Married Women of Childbearing Age

A Research Note on Income Pooling in Partnerships: Incorporating Nonresident Children

Income pooling is a common behavior among couples. However, cohabiting and married individuals in more complex families, namely those with stepchildren, are less likely to pool incomes. Similarly, income pooling might be unlikely when there are nonresident children, who could potentially draw resources outside the household, yet prior work has largely overlooked the role of nonresident children. We take advantage of a unique data set, the Family and Relationships Study, which allows us to not only identify shared and unshared children (i.e., stepchildren) within the household but also unshared children outside the household. Focusing on cohabiting and married individuals (N = 4,408), we find that those with resident unshared children are less likely to pool incomes but that nonresident children are unrelated to income pooling. The results confirm that household-level complexity is a key factor in couples' economic decision making.

Family Change and Changing Family Demography

Increases in life expectancy, high rates of movement into and out of couple relationships, and increasing exposure to stepfamilies raise new questions about who is in a family, the distinction between who lives together and who is a family member, and the extent to which family members are expected to meet the long-term obligations that define kinship. These questions are important because families have traditionally served as a vital private safety net for family members. Demographic changes increase family members' uncertainty about their relationships. Family ties are less stable and more uncertain among the economically disadvantaged, and uncertainty may exacerbate these disadvantages by weakening individuals' ability to rely on family members' support to alleviate hardship. I argue that demographers should focus on individuals' family relationships to gain insight into living arrangements and family dynamics. I also outline the development of family concepts and improvements in study design to identify principles that demographers should incorporate in new research to shed light on families' support for their members.

Is Variation in Biological and Residential Ties to Children Linked to Mothers' Parental Stress and Perceptions of Coparenting?

Mothers with children from prior relationships or with stepchildren may perceive greater challenges in parenting than their counterparts in less complex families. We use the Families and Relationships Study (FRS) to analyze parental stress and perceptions of co-parenting among cohabiting and married mothers with resident minor children (N = 679). Compared to mothers with only shared children, parental stress and perceptions of co-parenting generally do not differ when mothers have children from prior unions. However, mothers with resident stepchildren evaluate the distribution of childcare as less fair, consider their partners as less reliable co-parents, and rate their partner more poorly as a co-parent relative to those with no stepchildren. These findings suggest that creating a stepfamily through one's own children may not present additional parenting challenges or stressors whereas having stepchildren introduced through a partner may be linked to a different, and less positive, parenting experience.

MARRIAGE AND DISSOLUTION AMONG WOMEN'S COHABITATIONS: VARIATIONS BY STEPFAMILY STATUS AND SHARED CHILDBEARING

Cohabiting unions increasingly involve children, either born during the union and/or from prior relationships (i.e., stepchildren). Drawing from arguments about the institutionalization of cohabitation and stepfamilies as well as the family systems perspective, this paper examines dissolution and marriage risks among women's cohabiting unions by stepfamily status, configuration (which partner has children) and shared intended and unintended fertility using the 2006-2013 National Survey of Family Growth. A minority (32%) of 1st cohabitations, but the majority of 2nd (65%) and 3rd (75%) cohabitations, are stepfamilies. Stepfamily cohabitations are less likely to transition to marriage compared to non-stepfamily unions, especially among complex stepfamilies (both partners have children), but neither stepfamily status nor configuration affect dissolution. Shared intended and unintended births are associated with dissolution and marriage risks but largely only for non-stepfamily cohabitations, suggesting that shared childbearing is only indicative of the institutionalization for cohabitations that are not stepfamilies.
