Pathways to a Stable Union? Pregnancy and Childbearing Among Cohabiting and Married Couples

Educational Gradient of Multi-partner Fertility: First Estimates for the UK

Recent demographic changes in Western countries have resulted in higher rates of partnership dissolution and serial partnering, and an increase in childbearing across multiple partnerships. This has given rise to more complex family dynamics including multi-partner fertility (MPF), defined as having biological children with two or more partners. Yet estimates of MPF in the UK have not previously been available. This paper describes an 'indirect approach' to estimate the prevalence of MPF in the UK, for men and women, given different assumptions. The paper additionally explores differences in MPF according to own and parental educational attainment. Amongst those born in Britain in 1970, 12-14% of men and 15-18% of women experienced MPF by age 42, depending on the assumptions made. For most of the cohort, MPF occurred with two different coresidential partners. We have established that MPF is a common family formation in the UK, but there are large educational disparities in MPF prevalence.

The changing social gradient of marriage and cohabitation in seven Latin American countries

While research shows that cohabitation has increased significantly among highly educated individuals in Latin America, much less is known about how the relationship between educational attainment and first union formation has changed over time and across the region's countries. Accordingly, this paper describes the changes across cohorts in the type of first union (marriage or cohabitation) entered by women from seven Latin American countries. It also analyzes trends in the relationship between women's education and the type of first union within and between these countries. Using Demographic and Health Survey (DHS) data, life tables, discrete-time event history models, and predicted probabilities were estimated to analyze the changing determinants of first-union formation. The results pointed to an overall increase in first-union cohabitation over time, with some important differences across countries. The multivariate analysis suggested that women's education influences the type and sequencing of the first union, with socioeconomically disadvantaged women increasingly likely to transition to early unions and enter cohabitation rather than marriage.

Exploring the associations between number of children, multi-partner fertility and risk of obesity at midlife: Findings from the 1970 British Cohort Study (BCS70)

BACKGROUND

Early parenthood, high parity, and partnership separation are associated with obesity. However, the emergence of non-marital partnerships, serial partnering and childbearing across unions, means that it is important to consider their association to obesity. This paper examined the associations between number of biological children and multi-partner fertility (MPF)-defined as having biological children with more than one partner, with obesity at midlife.

METHOD

The sample consisted of 2940 fathers and 3369 mothers in the 1970 British Cohort Study. The outcome was obesity (BMI 30 or over) at age 46. Fertility and partnership histories ascertained the number of live biological children and MPF status by age 42. The associations were tested using logistic regression adjusting for confounders at birth, age 10 and age 16. Adult factors recorded at age 42 including age at first birth, smoking status, alcohol dependency, educational attainment and housing tenure were considered as mediators.

RESULTS

For fathers, obesity odds did not differ according to number of children or MPF. In unadjusted models, mothers with one child (OR 1.24 95%CI 1.01-1.51), mothers who had two children with two partners (OR 1.45 95%CI 1.05-1.99), and mothers who had three or more children with two or more partners (OR 1.51 95%CI 1.18-1.93) had higher odds of obesity. In adjusted models, there remained an association between mothers with one child and odds of obesity (OR 1.30 95%CI 1.05-1.60). All other associations were attenuated when confounders were included.

CONCLUSIONS

Mothers who had children with multiple partners had higher odds of obesity. However this association was completely attenuated when parental and child confounders were accounted for; suggesting that this association may be explained by confounding. Mothers who had one child only may be at increased odds of obesity, however this could be due to multiple factors including age at first birth.

Re-thinking Stepfathers' Contributions: Fathers, Stepfathers, and Child Wellbeing

Using data from a contemporary cohort of children, we revisit the question of whether children benefit from being close to and engaging in activities with a stepfather. We deploy the Fragile Families and Child Wellbeing Study, a birth cohort study of nearly 5000 children born in US cities in 1998-2000, with a large oversample of nonmarital births. We explore the relationships between stepfathers' closeness and active engagement and youth's internalizing and externalizing behaviors and school connectedness at ages 9 and 15 for between 550 and 740 children (depending on the wave) with stepfathers. We find that the emotional tenor of the relationship and level of active engagement between youth and their stepfathers are associated with reduced internalizing behaviors and higher school connectedness. Our findings suggest that stepfathers' roles seem to have evolved in ways that are more beneficial to their adolescent stepchildren than was previously the case.

Gender, union formation, and assortative mating among older women

This paper presents a search-theoretic model of union formation among women, aged 55 and older. Specifically, it provides new estimates of gender differentials in cohabitation and marriage at older ages, and documents recent patterns of assortative mating using data from the 2008-2017 American Community Survey. Our analyses reveal that cohabitation represents a much smaller share of all older unmarried women, all partnered women, and all women in comparison to patterns observed among their male counterparts. The results also reveal highly uneven patterns of union formation by age, race and marital history, which reflect demographically uneven constraints and preferences. Our analyses also document, for the first time, patterns of assortative mating at older ages. Shortages of similarly-aged men, especially among older African American women, seemingly heighten the likelihood of demographically mismatched unions. Older women are less likely to form unions with same-race or economically attractive partners, defined as men having a college-degree. This study shows that older single women, in general, are at a comparative disadvantage in the marriage market, both in forming co-residential unions and in finding partners who match their own social, demographic, and economic profiles. This paper highlights considerable heterogeneity in the experiences of America's older women. It calls for new theoretical approaches that acknowledge the unequal resources and bargaining power among older women in the marriage market.

Does Re-Partnering Behavior Spread Among Former Spouses?

This study focused on individuals' re-partnering behavior following a divorce and asked whether divorcees influence each other's new union formation. By exploiting the System of Social statistical Datasets (SSD) of Statistics Netherlands, I identified divorced dyads and examined interdependencies in their re-partnering behavior. Discrete-time event history models accounting for shared characteristics of divorcees that are likely to influence their divorce and re-partnering behavior simultaneously were estimated. Findings showed that the probability of re-partnering increased within the first two years following a former spouse's new union formation. Further analyses focusing on formerly cohabiting couples rather than divorcees also revealed significant associations in re-partnering behavior. Following a former romantic partner's new union formation, women were exposed to risk longer than men, due to men's quicker re-partnering. These results were robust to the falsification tests. Overall, findings indicate that the consequences of a divorce or breakup are not limited to the incidence itself and former romantic partners remain important in each other's life courses even after a breakup. With the increasing number of divorcees and changing family structures, it is important to consider former spouses as active network partners that may influence individual life courses.

Racial Pairings and Fertility: Do Interracial Couples Have Fewer Children?

OBJECTIVE

Our overall goal is largely descriptive-to compare recent fertility patterns between racially endogamous and exogamous couples in the United States. Evidence of lower fertility among exogamous or interracial couples arguably provides indirect evidence of social distance and cultural and economic integration.

BACKGROUND

The growth of interracial marriage and cohabitation has fueled the rise in biracial or mixed-race children. Fertility rates are uneven among racial and ethnic groups, seemingly rooted in stigma and cultural differences (e.g., fertility norms). Whether fertility is different among interracial couples is unclear: Fertility rates that largely conform to the population of racially endogamous White couples provide evidence of social integration whereas differential fertility may reveal gender dynamics in fertility decision-making, including power relationships that depend on the race of male and female partners.

METHOD

We pool data from the 2008 to 2017 American Community Survey to compare past-year fertility patterns among endogamously and interracially married and cohabiting couples.

RESULTS

Fertility is generally lower among racially exogamous than endogamous unions, especially among Asian American-White couples. Fertility among American Indian-White couples is much closer to patterns of White couples than of American Indian couples. Fertility among other interracial couples nevertheless varies by the race of male partners. That is, fertility of the Black male/White female and the Hispanic male/White female couples is similar to patterns found among endogamous Black and Hispanic couples, respectively. The White male/Black female and the White male/Hispanic female couples follow the fertility patterns of White couples.

CONCLUSION

In general, the fertility levels of interracial couples are intermediate between those of endogamous White couples and their endogamous Black, Hispanic, or American Indian counterparts, but vary significantly by the race-gender mix of partners.

The Relationship Context of Early Transitions to Parenthood: The Influence of Arrest

In the U.S., many young adults who have had contact with the criminal justice system are parents. Using the Toledo Adolescent Relationships Study (n = 1321), we drew on family demography and criminology literatures to examine the association between arrest, an understudied indicator of contact with the criminal justice system, and transitions to early parenthood. We also distinguished transitions to parenthood that occurred within four different relationship contexts: (1) single; (2) dating; (3) cohabiting; and (4) married. Using event history analyses, we found that young men and women who experienced an arrest transitioned to parenthood earlier than their counterparts who were not arrested. Further, men with an arrest, compared to men who had not been arrested, were more likely to report that they were dating the biological mother of their first child around the time of birth. In contrast, women with an arrest had an increased likelihood of having their first birth while cohabiting with the biological father. Our results highlighted the importance of a prior arrest for early transitions to parenthood and are relevant for understanding the intergenerational transmission of disadvantage and the diverging destinies of children and parents. Furthermore, the gender differences in the results illustrated the importance of including women in criminal justice analyses and men in fertility analyses.

Unintended Childbearing and Marital Instability: An Emphasis on Couples' Intentions

The birth of a child can negatively impact relationship functioning, especially if one or both partners did not intend to have a child. As such, unintended or disagreed-upon births may elevate the risk of dissolution. In this paper, we use the National Survey of Family Growth to consider how married couples characterize the intendedness of their first birth and examine its linkage with dissolution. Nearly one-third of first marital births are unintended by at least one parent. When fathers do not intend the birth, regardless of whether or not mothers do, couples report an elevated risk of dissolution.

Pathways to Parenthood in Social and Family Context: Decade in Review, 2020

OBJECTIVE

This article reviews research from the past decade on patterns, trends, and differentials in the pathway to parenthood.

BACKGROUND

Whether, and under what circumstances, people become parents has implications for individual identity, family relationships, the well-being of adults and children, and population growth and age structure. Understanding the factors that influence pathways to parenthood is central to the study of families and can inform policies aimed at changing childbearing behaviors.

METHOD

This review summarizes recent trends in fertility as well as research on the predictors and correlates of childbearing, with a focus on the United States and on research most relevant to family scholars. We document fertility differentials and prevailing explanations for variation across sub-groups and discuss alternative pathways to parenthood, such as adoption. The article suggests avenues for future research, outlines emerging theoretical developments, and concludes with a discussion of fertility policy.

RESULTS

U.S. fertility has declined in recent years; whether fertility rates will increase is unclear. Elements of the broader social context such as the Great Recession and increasing economic inequality have impacted pathways to parenthood, and there is growing divergence in behaviors across social class. Scholars of childbearing have developed theories to better understand how childbearing is shaped by life course processes and social context.

CONCLUSION

Future research on the pathways to parenthood should continue to study group differentials, refine measurement and theories, and better integrate men and couples. Childbearing research is relevant for social policy, but ideological factors impact the application of research to policy.

Contribution of the Rise in Cohabiting Parenthood to Family Instability: Cohort Change in Italy, Great Britain, and Scandinavia

In this study, we investigate through microsimulation the link between cohabiting parenthood and family instability. We identify mechanisms through which increases in cohabiting parenthood may contribute to overall increases in separation among parents, linking micro-level processes to macro-level outcomes. Analyses are based on representative surveys in Italy, Great Britain, and Scandinavia (represented by Norway and Sweden), with full histories of women’s unions and births. We first generate parameters for the risk of first and higher-order birth and union events by woman’s birth cohort and country. The estimated parameters are used to generate country- and cohort-specific populations of women with stochastically predicted family life courses. We use the hypothetical populations to decompose changes in the percentage of mothers who separate/divorce across maternal birth cohorts (1940s to 1950s, 1950s to 1960s, 1960s to 1970s), identifying how much of the change can be attributed to shifts in union status at first birth and how much is due to change in separation rates for each union type. We find that when cohabiting births were uncommon, increases in parents’ separation were driven primarily by increases in divorce among married parents. When cohabiting parenthood became more visible, it also became a larger component, but continued increases in parents’ divorce also contributed to increasing parental separation. When cohabiting births became quite common, the higher separation rates of cohabiting parents began to play a greater role than married parents’ divorce. When most couples had their first birth in cohabitation, those having children in marriage were increasingly selected from the most stable relationships, and their decreasing divorce rates offset the fact that increasing proportions of children were born in somewhat less stable cohabiting unions.

Change in the Stability of First Premarital Cohabitation Among Women in the United States, 1983-2013

The rapid growth in cohabitation over the past quarter-century necessitates studies of changes in the stability and outcomes of cohabitation. We utilized data from the 1988 National Survey of Family Growth (NSFG) and the most recent NSFG data from 2011-2013 to examine the outcomes of two comparable cohorts of first premarital cohabiting women (1983-1988 and 2006-2013). Our results showed that cohabitations formed between 2006 and 2013 lasted longer-18 months, on average-than those formed in the mid-1980s, which lasted for an average of 12 months. We found that the lengthening of cohabitation over time cuts across sociodemographic characteristics-race/ethnicity, education, and motherhood status-and resulted mostly from the declining rate of transitioning to marriage. We found some support for the diverging destinies perspective in that disparities in the outcomes of cohabitation by education and by cohabiting birth have widened over time. Our analyses showed that changes in the outcomes of first premarital cohabiting unions over the past three decades were not due to compositional shifts in cohabitors. These results demonstrate the evolving dynamics of cohabitation over a 30-year window.

"His" and "Hers": Meeting the Economic Bar to Marriage

Scholars have suggested that low-income parents avoid marriage because they have not met the so-called economic bar to marriage. The economic bar is multidimensional, referring to a bundle of financial achievements that determine whether couples feel ready to wed. Using the Building Strong Families data set of low-income parents (n = 4,444), we operationalized this qualitative concept into a seven-item index and examined whether couples who met the economic bar by achieving the majority of the items were more likely to marry than couples who did not. Meeting the bar was associated with a two-thirds increase in marriage likelihood. The bar was not positively associated with cohabitation, suggesting that it applies specifically to marriage. When we examined different definitions of the bar based on whether the mother, father, or both parents contributed items, all variants were associated with marriage, even if the bar was based on the mother's economic accomplishments alone. When mothers contributed to the economic bar, they reported significantly higher relationship quality. Our results reinforce the importance of the multidimensional economic bar for marriage entry, highlighting the role of maternal economic contributions in low-income relationships.

A Research Note on the Stability of Coresidential Unions Formed Postconception

There is a large literature examining the stability of mid-pregnancy unions, and parallel work on unions formed after a nonmarital birth, but research has yet to compare pre- and post-birth unions and simultaneously consider whether the union is with the father or a new partner. Using the National Longitudinal Survey of Youth, 1997 Cohort, the author compares the stability of coresidential unions (cohabitations and marriages) among three groups of mothers with non-union first conceptions: those with a mid-pregnancy union with the father (N = 203), those with a post-birth union with the father (N = 333), and those with a union with a new partner (N = 342). Compared to mid-pregnancy unions with the father, post-birth father unions are 35% more likely to dissolve. New-partner unions are more likely to dissolve than both types of father unions. These associations persist when accounting for union type and socioeconomic and demographic characteristics.

Marriage Markets and Intermarriage: Exchange in First Marriages and Remarriages

Drawing on data from the American Community Survey, we compare patterns of assortative mating in first marriages, remarriages, and mixed-order marriages. We identify a number of ascribed and achieved characteristics that are viewed as resources available for exchange, both as complements and substitutes. We apply conditional logit models to show how patterns of assortative mating among never-married and previously married persons are subject to local marriage market opportunities and constraints. The results reveal that previously married individuals “cast a wider net”: spousal pairings are more heterogamous among remarriages than among first marriages. Marital heterogamy, however, is reflected in systematic evidence of trade-offs showing that marriage order (i.e., status of being never-married) is a valued trait for exchange. Never-married persons are better positioned than previously married persons to marry more attractive marital partners, variously measured (e.g., highly educated partners). Previously married persons—especially women—are disadvantaged in the marriage market, facing demographic shortages of potential partners to marry. Marriage market constraints take demographic expression in low remarriage rates and in heterogamous patterns of mate selection in which previously married partners often substitute other valued characteristics in marriage with never-married persons.
