Nonmarital childbearing: influences of education, marriage, and fertility

Nonmarital childbearing in Russia: second demographic transition or pattern of disadvantage?

Using retrospective union, birth, and education histories that span 1980-2003, this study investigates nonmarital childbearing in contemporary Russia. We employ a combination of methods to decompose fertility rates by union status and analyze the processes that lead to a nonmarital birth. We find that the increase in the percentage of nonmarital births was driven mainly by the growing proportion of women who cohabit before conception, not changing fertility behavior of cohabitors or changes in union behavior after conception. The relationship between education and nonmarital childbearing has remained stable: the least-educated women have the highest birth rates within cohabitation and as single mothers, primarily because of their lower probability of legitimating a nonmarital conception. These findings suggest that nonmarital childbearing Russia has more in common with the pattern of disadvantage in the United States than with the second demographic transition. We also find several aspects of nonmarital childbearing that neither of these perspectives anticipates.

Incorporating children's lives into a life course perspective on stress and mental health

Emerging themes in demography, developmental medicine, and psychiatry suggest that a comprehensive understanding of mental health across the life course requires that we incorporate the lives of children into our research. If we can learn more about the ways in which the stress process unfolds for children, we will gain important insights into the factors that influence initial set points of trajectories of mental health over the life course. This will simultaneously extend the scope of the stress process paradigm and elaborate the life course perspective on mental health. Incorporating children's lives into the sociology of mental health will also extend the intellectual influence of the discipline on sociomedical and biomedical research on mental illness. I contend that sociology's greatest promise in understanding trajectories of mental health across the life course lies in a systematic analysis of the social and social-psychological conditions of children, the stressful experiences that arise out of these conditions, and the processes that mediate and moderate the stress process in childhood. In this regard, there are three major issues that sociologists could begin to address: (1) the identification of structural and institutional factors that pattern children's exposure to stress; (2) the construction of a stress universe for children; and (3) the identification of key elements of the life course perspective that may set or alter trajectories of mental health in childhood and adolescence.

Single Mothers, Single Fathers: Gender Differences in Fertility after a Nonmarital Birth

Research on nonmarital fertility has focused almost exclusively on unmarried mothers, due in part to a lack of fertility information for men. Cycle 6 of the National Survey of Family Growth allows exploration of nonmarital fertility for both genders. We compare the characteristics of unmarried first-time mothers (n = 2,455) and fathers (n = 797), use event history techniques to model second birth hazards, and examine the distribution of men's and women's second births across types of relationships. Our analysis is motivated by questions about how selection into nonmarital fertility relates to subsequent fertility behavior and by theories of mate selection and the "relationship" market. We find that unmarried mothers are more likely to have a second birth than unmarried fathers, driven largely by a higher hazard of having a noncoresidential second birth.

The relationship context of nonmarital childbearing in the U.S

Using Early Childhood Longitudinal Study-Birth Cohort data, we present estimates of nonmarital births in the United States in 2001, both within and outside of cohabiting unions. We additionally examine how mother and father characteristics are associated with the relationship context at birth, and assess racial/ethnic differences in these relationships. We find that 52% of nonmarital births (and 19% of all births) occur within cohabitating unions-a substantial increase in cohabiting births since the early 1990s. The increase in cohabiting births among white and Hispanic women largely reflects a shift from marital to cohabiting births, while the increase in cohabiting births among black women largely reflects a shift from single to cohabiting births. Mother and father characteristics, including marital and fertility histories, are associated with relationship status at birth. However, with the exception of mother's education, only the association between father characteristics and relationship status at birth vary by race and ethnicity.

Order Amidst Change: Work and Family Trajectories in Japan

Substantial family and work macro-level change has been occurring in Japan. Examples include a decline in the availability of jobs that afford lifetime protection against unemployment, an increase in jobs that do not carry benefits such as a pension, an increase in age at marriage and at first birth, and an increase in marital dissolution. Using life history data from the 2000 National Survey on Family and Economic Conditions, young Japanese appear to have responded to these macro-level changes in a fairly orderly manner. Marriage and childbearing have been postponed, but marriage still precedes childbearing. Education is completed prior to starting work. For men, once work commences they continue working. For women, the classic conflict between work and family roles is evident. For men and women in both the family and work spheres Japanese young adults have more orderly life course trajectories than American young adults.

The educational gradient of childbearing within cohabitation in Europe

Nearly every European Country has experienced some increase in nonmarital childbearing, largely due to increasing births within cohabitation. Relatively few studies in Europe, however, investigate the educational gradient of childbearing within cohabitation or how it changed over time. Using retrospective union and fertility histories, we employ competing risk hazard models to examine the educational gradient of childbearing in cohabitation in eight countries across europe. In all countries studied, birth risks within cohabitation demonstrated a negative educational gradient. When directly comparing cohabiting fertility with marital fertility, the negative educational gradient persists in all countries except Italy, although differences were not significant in Austria, France, and West Germany. To explain these findings, we present an alternative explanation for the increase in childbearing within cohabitation that goes beyond the explanation of the Second Demographic Transition and provides a new interpretation of the underlying mechanisms that may influence childbearing within cohabitation.

US fertility prevention as poverty prevention: an empirical question and social justice issue

PURPOSE

This paper examines the impact of the US welfare reform family-cap policy on the childbearing decisions of poor and low-income women by posing two complementary questions, both placed within a broader historical context. Specifically, it raises an empirical question pertaining to the family cap's effectiveness and a social justice question pertaining to the policy's ethical and legal justification in terms of human and reproductive rights.

METHODS

To address the first question, a thorough review of past and current research pertaining to the family cap at both the state and national levels is provided. The second question is addressed with an overview of international human and reproductive rights documents of relevance to the family-cap policy, as well as an analysis of the covenants' numerous components with which the family cap is in conflict. Finally, this paper situates the family cap in its historical context by investigating previous governmental attempts to control and regulate the reproductive health and rights of poor women and women of color in the United States.

MAIN FINDINGS

The majority of empirical analyses of the family cap have found that the policy has not had an impact on poor women's reproductive health behaviors. In addition, the exclusive application of this policy to poor women receiving cash assistance is demonstrated to be in violation of eight international human and reproductive rights documents, several of which the US is a signatory.

CONCLUSION

These two findings make a strong case that policy makers and social and health researchers alike critically reexamine whether a policy that has not achieved its ostensible goal and is applied in a disparate manner-primarily to poor women and families and women of color-should continue to be implemented by the states.

Consequences of family disruption on children's educational outcomes in Norway

Using high-quality data from Norwegian population registers, we examine the relationship between family disruption and children's educational outcomes. We distinguish between disruptions caused by parental divorce and paternal death and, using a simultaneous equation model, pay particular attention to selection bias in the effect of divorce. We also allow for the possibility that disruption may have different effects at different stages of a child's educational career. Our results suggest that selection on time-invariant maternal characteristics is important and works to overstate the effects of divorce on a child's chances of continuing in education. Nevertheless, the experience of marital breakdown during childhood is associated with lower levels of education, and the effect weakens with the child's age at disruption. The effects of divorce are most pronounced for the transitions during or just beyond the high school level. In models that do not allow for selection, children who experienced a father's death appear less disadvantaged than children whose parents divorced. After we control for selection, however differences in the educational qualifications of children from divorced and bereaved families narrow substantially and, at mean ages of divorce, are almost non-existent.

Disparities in academic achievement and health: the intersection of child education and health policy

Recent data suggest that that the United States is failing to make significant progress toward the Healthy People 2010 goal of eliminating health disparities. One missing element from the US strategy for achieving this goal is a focus on gaps in child development and achievement. Academic achievement and education seem to be critical determinants of health across the life span and disparities in one contribute to disparities in the other. Despite these linkages, national policy treats child education and health as separate. Landmark education legislation, the No Child Left Behind Act of 2001, is due for Congressional reauthorization. It seeks to eliminate gaps in academic child achievement by 2014. It does so by introducing accountability for states, school districts, and schools. In this special article, we review health disparities and contributors to child achievement gaps. We review changes in achievement gaps over time and potential contributors to the limited success of the No Child Left Behind Act of 2001, including its unfunded mandates and unfounded assumptions. We conclude with key reforms, which include addressing gaps in child school readiness through adequate investment in child health and early education and reductions in child poverty; closing the gap in child achievement by ensuring equity in school accountability standards; and, importantly, ensuring equity in school funding so that resources are allocated on the basis of the needs of the students. This will ensure that schools, particularly those serving large numbers of poor and minority children, have the resources necessary to promote optimal learning.

Joint analysis of multi-level repeated measures data and survival: an application to the end stage renal disease (ESRD) data

Shared random effects models have been increasingly common in the joint analyses of repeated measures (e.g. CD4 counts, hemoglobin levels) and a correlated failure time such as death. In this paper we study several shared random effects models in the multi-level repeated measures data setting with dependent failure times. Distinct random effects are used to characterize heterogeneity in repeated measures at different levels. The hazard of death may be dependent on random effects from various levels. To simplify the estimation procedure, we adopt the Gaussian quadrature technique with a piecewise log-linear baseline hazard for the death process, which can be conveniently implemented in the freely available software aML. As an example, we analyze repeated measures of hematocrit level and survival for end stage renal disease patients clustered within a randomly selected 126 dialysis centers in the U.S. renal data system data set. Our model is very comprehensive yet easy to implement, making it appealing to general statistical practitioners.

High-Risk Subsequent Births Among Co-Residential Couples: The Role of Fathers, Mothers, and Couples

This study examines predictors of a cumulative measure of high-risk births, rather than single risks separately, as in prior research. Using the Early Childhood Longitudinal Study-Birth Cohort survey, we incorporate data from fathers and mothers to assess characteristics associated with births subsequent to a focal child's birth within high-risk circumstances. Components of a high-risk birth include: high-parity, very closely-spaced, or births to unmarried couples, unhappy couples, or couples in high-conflict relationships. Both fathers' and mothers' pregnancy intentions affect whether couples have a subsequent high-risk birth. The odds of a high-risk subsequent birth, relative to no birth and to a low-risk birth, are more than twice as high if only the father intended the birth of the previous child rather than if the child was intended by both the mother and father. High-risk subsequent births are much more likely among couples where the prior child was high risk and where family income was low, and lower where both father and mother had lived with both biological parents. Findings highlight the importance of father data in fertility research.

Early Claiming of Social Security Benefits and Labor Supply Behavior of Older Americans

The labor supply incentives provided by the early retirement rules of the United States Social Security Old Age benefits program are of growing importance as the Normal Retirement Age (NRA) increases to 67, and the labor force participation of Older Americans starts to increase. These incentives allow individuals who claim benefits before the NRA but continue to work, or return to the labor force, to increase their future rate of benefit pay by having benefits withheld. Since the adjustment of the benefit rate takes place only after the NRA is reached, benefits received before the NRA can become actuarially unfair for those who continue to work after claiming. Consistent with these incentives, estimates from bivariate models of the monthly labor force exit and claiming hazards using data from the Health and Retirement Study indicate that early claimers who do not withdraw from the labor force around the time they claim are increasingly likely to stay in the labor force.

Older sexual partners during adolescence: links to reproductive health outcomes in young adulthood

CONTEXT

Sex at a young age with an older partner has been linked to poor reproductive health outcomes during adolescence, but minimal research has examined the influence of teenagers' having an older sexual partner on reproductive health outcomes during the transition to young adulthood.

METHODS

Logistic regression and contrast analyses of three waves of data from the National Longitudinal Study of Adolescent Health were used to examine whether individuals who had had sex before age 16 with a partner at least three years their senior were at increased risk of becoming teenage or unmarried parents or of contracting an STD by young adulthood.

RESULTS

Ten percent of females and 2% of males had had early sex with an older partner. These females were more likely to acquire an STD as young adults than were those whose riskiest relationship was before age 16 with a similar-aged partner (odds ratio, 2.1) or at age 16 or later with a similar-aged or older partner (2.4 and 2.6, respectively). For males, having sex before 16, regardless of partner age, was associated with an elevated STD risk (odds ratio, 1.9), although controlling for relationship history characteristics attenuated the association.

CONCLUSIONS

Adolescents, particularly young adolescents, should be made aware of the potential risks associated with having older sexual partners. In particular, program providers should be alerted that females who engage in early sexual activity with older partners are at especially high risk of experiencing adverse reproductive health consequences.

Multipartnered fertility among young women with a nonmarital first birth: prevalence and risk factors

CONTEXT

Although early nonmarital fertility has been well studied, less attention has been paid to the subsequent fertility of young unwed mothers. In particular, the frequency with which these young women have subsequent births with a new partner (multipartnered fertility) and the risk factors associated with doing so are unknown.

METHODS

The proportion of young women who had a first birth and the proportion who subsequently had a child with a new partner were determined among a sample of participants in Waves 1 (1995) and 3 (2001-2002) of the National Longitudinal Study of Adolescent Health. Multivariate analyses identified characteristics associated with multipartnered fertility.

RESULTS

By Wave 3, when these young women were 19-25 years old, 29% had had a first birth, and 3% had had births with multiple partners. Among women with a nonmarital first birth, 14% subsequently had a birth with another partner, and 41% with two or more children had had multiple partners. The prevalence of multipartnered fertility differed sharply by race and ethnicity. Most new-partner births occurred outside of marriage, especially among black women. Respondents who had no contact with their partner after informing him of their first pregnancy or who had not wanted to have a child with him had an increased likelihood of multipartnered fertility.

CONCLUSIONS

The context in which first births occur sets the stage for subsequent childbearing. Programs that help women avoid having births in unfavorable circumstances, such as in early and unstable relationships, may reduce the prevalence of multipartnered fertility.

Changing compatibility of cohabitation and childbearing between young British women born in 1958 and 1970

We investigate the effect of parenthood on whether non-marital unions led to marriage or parting for two cohorts of British women when they were aged between 16 and 29. We compare the effect of conceptions leading to births and the presence and characteristics of children on the odds that a cohabitation was dissolved, or that it was converted to marriage, for women born in 1958 and 1970. A multilevel, multiprocess, competing-risks model allows for multiple cohabitation per woman and endogeneity of fertility status. We find that cohabiting couples' response to impending parenthood and the presence of children changed over time. In particular, the proportion of cohabiting couples who married before a birth decreased and, in the 1970 cohort only, the risk of dissolution declined during pregnancy. There is also evidence that the presence of a child cemented a cohabiting union for women from the 1970, but not the earlier, cohort.

The rising share of nonmarital births: Fertility choice or marriage behavior?

Much of the sharp rise in the share of nonmarital births in the United States has been attributed to changes in the fertility choices of unmarried and married women—in response, it is often argued, to public policy. In contrast, we develop and test a model that attributes the rise to changes in marriage behavior, with no necessary changes in fertility. A variety of empirical tests strongly support this conclusion and invites focused attention to issues related to marriage behavior as well as to the interactions between marriage and fertility.

The relationship between childbearing and transitions from marriage and cohabitation in Britain

In this article, we describe a general framework for the analysis of correlated event histories, with an application to a study of partnership transitions and fertility among a cohort of British women. Using a multilevel, multistate competing-risks model, we examine the relationship between prior fertility outcomes (the presence and characteristics of children and current pregnancy) and the dissolution of marital and cohabiting unions and movements from cohabitation to marriage. Using a simultaneous-equations model, we model these partnership transitions jointly with fertility, allowing for correlation between the unobserved woman-level characteristics that affect each process. The analysis is based on the partnership and birth histories that were collected for the 1958 birth cohort (National Child Development Study) aged 16–42. The findings indicate that preschool children have a stabilizing effect on their parents’ partnership, whether married or cohabiting, but the effect is weaker for older children. There is also evidence that although pregnancy precipitates marriage among cohabitors, the odds of marriage decline to prepregnancy levels following a birth.

Union formation in fragile families

In this article, we use data from a new longitudinal survey--the Fragile Families and Child Wellbeing Study--to examine union formation among unmarried parents who have just had a child together. We used multinomial logistic regression to estimate the effects of economic, cultural/interpersonal, and other factors on whether (relative to having no romantic relationship) parents are romantically involved and living apart, cohabiting, or married to each other about one year after the child's birth. Net of other factors (including baseline relationship status), women's education and men's earnings encourage marriage. Cultural and interpersonal factors also have strong effects: women's trust of men, both parents' positive attitudes toward marriage, and both parents' assessment of the supportiveness in their relationship encourage marriage. Supportiveness also encourages cohabitation, while fathers having a problem with alcohol or drugs and reporting higher conflict in the relationship discourage cohabitation: Fathers' physical violence deters couples' remaining in romantic nonresident relationships.

Appropriate methods for analyzing the effect of method choice on contraceptive discontinuation

The contraceptive method chosen is an important determinant of contraceptive discontinuation. However, method choice is endogenous to contraceptive discontinuation. Using data from the 1997 Indonesia Demographic and Health Survey, we apply a multilevel multi-process model to examine the impact of method choice on three types of contraceptive discontinuation. We confirm that method choice is endogenous to the processes of contraceptive abandonment and method switching, but not failure. Ignoring the endogeneity of contraceptive choice leads to various biases in the magnitude of estimated effects of method choice on abandonment and method switching, but the general conclusions are robust to these biases.
