Family Complexity and Children's Behavior Problems over Two U.S. Cohorts.

OBJECTIVE: We consider the prevalence of family complexity and its association with children's externalizing behavior problems over children's life course and over historical time. BACKGROUND: A growing literature has demonstrated the prevalence and multidimensional nature of family complexity and its association with child behavior. The nature/strength of this association may have changed in recent cohorts as family complexity has become more common. METHOD: Data are from the 1997 and 2014 cohorts of the Panel Study of Income Dynamics Child Development Supplement. Samples represent U.S. children ages 0-12 years born since 1985 (N=5,030). Ordinary least squares regression estimated change in the association between family complexity and behavior between cohorts. Difference-in-difference models estimated baseline and longitudinal differences in children's behavior as linked to family complexity. RESULTS: The prevalence of family complexity has stabilized over the last two decades, and the antecedents to parental repartnering and complex sibship organization remain similar. The expectation that increasing family complexity contributes to elevated behavior problem scores was not supported. Instead, children who eventually acquired a step- or half-sibling or who experienced parents' union dissolution had elevated behavior problems prior to those changes. CONCLUSION: The prevalence of and precursors to complex family organization were stable across recent child cohorts. The observed association between family complexity and child behavior problems may be attributable to selection mechanisms linked to both parents' family formation trajectories and to children's behavior, rather than to family change itself.

Race/Ethnic Differences in Nonresident Fathers' Involvement after a Nonmarital Birth.

OBJECTIVES: This article examines how the levels of nonresidential father involvement (over child ages 1 to 9) differ by race/ethnicity (comparing White, Black and Hispanic fathers), and then considers how individual and couple characteristics may 'account for' any observed differences. METHOD: Data from the Fragile Families and Child Wellbeing Study (N = 2,447) and random effects models were used to examine how nonresidential father involvement (with respect to time, engagement, shared responsibility, and coparenting with mothers) is differentiated by race and ethnicity. RESULTS: Overall, Black nonresident fathers were significantly more likely to spend time and engage in activities with their children as compared to Hispanic fathers-but not White fathers. Black fathers also shared responsibilities more frequently and displayed more effective coparenting than Hispanic and White fathers. CONCLUSIONS: Fathers' involvement with children is shown to differ across major race/ethnic groups, with implications for children as well as for future research and public policy.

Trajectories of relationship supportiveness after childbirth: Does marriage matter?

Relationship quality for married couples typically declines after the birth of a (first) child, as parenthood brings new identities, stresses, and responsibilities for mothers and fathers. Yet, it is less clear whether nonmarital relationship quality follows a similar trajectory, particularly given the greater selectivity of nonmarital relationships that persist over time. This paper uses data from the Fragile Families and Child Wellbeing Study (N = 3,459) with latent growth curve models to examine relationship quality (measured by mothers' perceived supportiveness about fathers) for married and unmarried couples over nine years after a child's birth. Findings suggest that marriage at birth is protective for relationship supportiveness over time, net of various individual characteristics associated with marriage, compared to all unmarried couples at birth; however, marriage does not differentiate supportiveness compared to the subset of unmarried couples who remain stably together. Also, unmarried couples who get married after the birth have more supportive relationships compared to all unmarried couples who do not marry-though less so when compared to couples who remain stably together.

Fathers' Investments of Money and Time Across Residential Contexts.

Fathers' roles in family life have changed dramatically over the past 50 years. In addition to ongoing breadwinning responsibilities, many fathers are now involved in direct caregiving and engagement with children. Yet there is considerable variation in what fathers do, especially depending on whether they live with or away from their child. In this article, the authors use data from the Fragile Families and Child Wellbeing Study (N = 3,869) to describe how fathers' economic capacities (money) and direct involvement with children (time) are associated over child ages 1 to 9 for resident versus nonresident fathers, net of confounding factors. They found suggestive evidence that money and time investments operate differently across residential contexts: Resident fathers experience a trade-off between market work and time involved with children. In contrast, nonresident fathers' higher economic capacities are associated with more time involvement, underscoring the greater challenge for such fathers to remain actively involved.

Patterns and predictors of coparenting after unmarried parents part.

Nonmarital childbearing has increased dramatically during the past several decades, and the majority of unmarried couples will break up while their child is still young. As a result, many children will be raised by their biological parents living apart, ideally working together as effective coparents. In this article, we use data from the Fragile Families and Child Wellbeing Study (N = 1,193) to describe the trajectories of coparenting over 6 years following the end of a nonmarital relationship and to identify individual and interpersonal characteristics associated with better coparenting over time. Results from growth mixture models (GMMs) suggest that there are 4 primary trajectories of coparenting over time, and results from multinomial logit models show that couples' race/ethnicity, maternal health, and parents' relationship and fertility characteristics are the most salient predictors of coparenting trajectories. These results highlight the heterogeneity of parents' interaction vis-à-vis their common child after a nonmarital union dissolves and point to the challenges of supporting families and children amid high instability.

Educational differences in early childbearing: A cross-national comparative study.

BACKGROUND: Recent research on fertility in industrialized countries focuses primarily on delayed childbearing, despite the facts that large numbers of women continue to enter parenthood at relatively young ages and that early childbearing has been linked to economic disadvantage. OBJECTIVE: This cross-national comparative study describes relationships between women's educational attainment and young age at first birth and evaluates the extent to which these differences have changed over time for women born 1955-1981. METHODS: Defining 'early' childbearing as the age by which 20% of first births have occurred to women in a given birth cohort and country, we describe differences in early childbearing by educational attainment across three cohorts of women in 20 countries. RESULTS: We find a strong negative educational gradient in early childbearing across all 20 countries and some evidence of an increase in the relative prevalence of early childbearing among the least-educated women. In 10 countries, the relative prevalence of early childbearing among women with low education is significantly higher for one or both of the more recent birth cohorts compared to the earliest cohort. However, many countries show no significant change, and in one country (Poland) there is modest evidence of a decreasing educational gap. CONCLUSIONS: Evidence that educational differences in early childbearing have grown in some countries is generally consistent with the notion of family bifurcation and 'diverging destinies' by socioeconomic status. However, the pattern is not universal and future work should examine the various factors that shape these patterns, including the role of public policies.

Parents' Relationship Quality and Children's Behavior in Stable Married and Cohabiting Families.

Although an extensive literature has shown that family structure is linked with child well-being, less well understood is how the dynamics within families affect children, in particular the extent to which positive mother-father relationship quality is linked with children's outcomes. In this study the authors used data from the Fragile Families and Child Wellbeing Study (N = 773) to examine how couple supportiveness in stable coresident families is related to children's externalizing and internalizing behavioral problems over ages 3 through 9. Using latent growth curve and fixed effects models, they found that parents' greater supportiveness has a slight association with lower levels of children's behavioral problems. Using cross-lagged structural equation models to examine the direction of the association, they also found some evidence that parents' relationship quality and children's behavioral problems are reciprocally related. Overall, this study suggests that more positive couple interactions are beneficial for children residing with both of their biological parents.

Examining the antecedents of U.S. nonmarital fatherhood.

Despite the dramatic rise in U.S. nonmarital childbearing in recent decades, limited attention has been paid to factors affecting nonmarital fatherhood (beyond studies of young fathers). In this article, we use data from the 2002 National Survey of Family Growth and the National Longitudinal Survey of Youth 1979 cohort to examine the antecedents of nonmarital fatherhood, as compared to marital fatherhood. Overall, we find the strongest support across both data sets for education and race/ethnicity as key predictors of having a nonmarital first birth, consistent with prior literature about women's nonmarital childbearing and about men's early/teenage fatherhood. Education is inversely related to the risk of nonmarital fatherhood, and minority (especially black) men are much more likely to have a child outside of marriage than white men. We find little evidence that employment predicts nonmarital fertility, although it does strongly (and positively) predict marital fertility. High predicted earnings are also associated with a greater likelihood of marital childbearing but with a lower likelihood of nonmarital childbearing. Given the socioeconomic disadvantage associated with nonmarital fatherhood, this research suggests that nonmarital fatherhood may be an important aspect of growing U.S. inequality and stratification both within and across generations.

What Kids Get from Parents: Packages of Parental Involvement across Complex Family Forms.

While demographers have continued to document the notable family changes that have occurred in recent decades, the nature of family functioning across diverse family forms is less well understood. In particular, we know little about the level and quality of parental investment that children receive across a range of contemporary family types. In this paper, we use data from a recent U.S. urban birth cohort to examine the 'package' of parental involvement that young children receive in two key domains across family types. We aggregate parent-child engagement across three potential parent(-figures)-biological mothers, biological fathers (resident or non-resident), and resident social fathers-and also assess the child's household income. We examine parental investments at child age 5 and changes in investments between child ages 1 and 5 by family structure categories. Overall, we find that children living with both of their married biological parents are advantaged with respect to both economic resources and parental engagement, while children living with single mothers-or their mother and a cohabiting social father-fare especially poorly in both domains; children in married social-father families receive higher overall levels of parental engagement than those in biological-father families but are much less economically advantaged. Our research sheds light on how changing family demography is related to parental investments in children, which may have implications for public policies designed to support disadvantaged families.

"Like Parent, Like Child?": The intergenerational transmission of nonmarital childbearing.

Data from the 2002 National Survey of Family Growth (N=11,180) are used to examine the intergenerational transmission of nonmarital childbearing for US men and women. Findings suggest that being born to unmarried parents increases the risk of offspring having a nonmarital first birth, net of various confounding characteristics. This intergenerational link appears to particularly operate via parents' breaking up before offspring are age 14 and offspring's young age at first sex. While the link across two generations in nonmarital childbearing is not accounted for by parents' socioeconomic status (measured as fathers' education), several mediating factors vary by socioeconomic background. Gender and race/ethnicity also moderate the intergenerational transmission of nonmarital childbearing. This research sheds light on the prevalence of, and process by which, nonmarital childbearing is repeated across generations, which has important implications for long-term social stratification and inequality.

Mothers' Repartnering after a Nonmarital Birth.

This paper examines the prevalence, predictors and outcomes of unmarried mothers' repartnering patterns following a nonmarital birth. Results indicate that, within five years after a birth, approximately two-thirds of unmarried mothers ended their relationship with the focal child's biological father, and over half of these mothers entered new partnerships. Among those who repartnered, 60 percent of mothers formed unions with men with higher economic capabilities than their former partners, 20 percent formed unions with men with similar capabilities, and 20 percent formed unions with men with lower capabilities. This pattern holds for both nonresidential and coresidential unions. Our findings are consistent with marriage market, learning, and evolutionary biology theories about union formation, and they provide support for qualitative evidence that unmarried mothers have high standards for new partners. While many mothers are able to successfully find new partners with better economic capabilities, many other mothers remain unpartnered, likely due (at least in part) to the limited pool of potential partners with relatively high levels of economic capabilities.

Multipartnered Fertility and Depression among Fragile Families.

We used data from the Fragile Families and Child Wellbeing Study to examine the association between multipartnered fertility (MPF)-when parents have children with more than one partner-and depression. Random effects models suggested that MPF is associated with a greater likelihood of depression, net of family structure and other covariates. However, these associations disappeared in more conservative fixed effects models that estimated changes in MPF as a function of changes in depression. Results also suggested that social selection may account for the link between MPF and depression for fathers (but not mothers), as depressed fathers with no MPF were more likely to have a child by a new partner four years later. Ultimately, MPF and depression may be reciprocally related and part of broader processes of social disadvantage.

"Couples as Partners and Parents over Children's Early Years"

We used data from the Fragile Families and Child Wellbeing Study to examine how couple relationship quality and parental engagement are linked over children's early years-when they are infants, toddlers, and preschoolers. Our sample included 1,630 couples that were coresident over years 1 to 3 and 1,376 couples that were coresident over years 3 to 5 (1,196 over both periods). Overall, we found that better relationship quality predicted greater parental engagement for both mothers and fathers-especially in the infant to toddler years; in contrast, we found little evidence that parental engagement predicted future relationship quality. Married and cohabiting couples were generally similar in how relationship quality and parenting were linked.

Intergenerational Relationships and Union Stability in Fragile Families.

Using data from the Fragile Families and Child Well being Study (N= 2,656), we examined the association between intergenerational relationships and parents' union stability five years after a baby's birth. Results showed that more amiable relationships between parents and each partner's parents, and more time children spent with paternal grandparents, were associated with increased odds that parents were co-residing by the time their focal child was age five. More time that children spent with maternal grandparents reduced union stability, although this result was not robust to methods that better address selection. These findings underscore the importance of the broader social contexts affecting couple stability. Findings further suggest that even amidst changing demographic conditions, intergenerational family ties are important for couples-and by extension-their children.

Coparenting and nonresident fathers' involvement with young children after a nonmarital birth.

We use data from the Fragile Families and Child Wellbeing Study to investigate the association between coparenting quality and nonresident fathers' involvement with children over the first five years after a nonmarital birth. We find that about one year after a nonmarital birth, 48% of fathers are living away from their child, rising to 56% and then to 63% at three and five years, respectively Using structural equation models to estimate cross-lagged effects, we find that positive coparenting is a strong predictor of nonresident fathers' future involvement, whereas fathers' involvement is only a weak (but significant) predictor of future coparenting quality. The positive effect of coparenting quality on fathers' involvement is robust across several techniques designed to address unobserved heterogeneity and across different strategies for handling missing data. We conclude that parents' ability to work together in rearing their common child across households helps keep nonresident fathers connected to their children and that programs aimed at improving parents' ability to communicate may have benefits for children irrespective of whether the parents' romantic relationship remains intact.

Parenting Practices of Resident Fathers: The Role of Marital and Biological Ties.

This paper uses data from the Fragile Families and Child Wellbeing Study (N = 2,098) to examine differences in the parenting practices of four types of resident fathers, defined by their biological relationship to a focal child and their marital status with regard to the focal child's mother. Regression results suggest that biological and social (i.e., stepfathers or mothers' cohabiting partners) fathers differ significantly, and in some unexpected ways, on most measures of parenting. However, a considerable portion of these differences can be explained by variation in the background characteristics of the individuals and families in each group. Additionally, difference-in-difference analyses reveal a stronger link between marriage and higher quality parenting practices among social fathers than among biological fathers.

Welfare reform, fertility, and father involvement.

Recognizing that most poor families are single-parent families, the federal welfare reform law of 1996 emphasized the responsibility of both parents to support their children. In addition to strengthening the child support enforcement system, the law included several provisions designed to decrease childbearing outside of marriage and to promote two-parent families. This article focuses on the important role that fathers play in children's lives and how public policies have affected childbearing and father involvement. Key observations are: Compared with children living with both biological parents, children in father-absent families often have fewer economic and socioemotional resources from their parents, and do not fare as well on many outcome measures. Efforts to reduce the rising number of father-absent families by focusing on preventing unwanted pregnancy among unmarried women, especially teen girls, have met with some success; those programs seeking to alter adolescents' life opportunities in addition to providing education or family planning services appear to hold the most promise. Efforts to encourage greater father involvement by focusing almost exclusively on increasing absent parents' child support payments reap only minimal benefits for poor children because their absent parents often have few resources and little incentive to make support payments. To date, efforts to increase the emotional involvement of unmarried fathers with their children have produced disappointing results, but new research suggests that such programs can make a difference when targeting fathers at the time of a child's birth. Many children spend some time living away from their fathers, deprived of the financial and emotional resources they can provide. Because of the importance of fathers to child well-being, the authors conclude that new directions in research and public policies are needed to encourage greater father involvement across the wide diversity of family arrangements in society today.
