The influence of nonmarital childbearing on the formation of first marriages

We document a negative association between nonmarital childbearing and the subsequent likelihood of first marriage in the United States, controlling for a variety of potentially confounding influences. Nonmarital childbearing does not appear to be driven by low expectations of future marriage. Rather, it tends to be an unexpected and unwanted event, whose effects on a woman’s subsequent likelihood of first marriage are negative on balance. We find that women who bear a child outside marriage and who receive welfare have a particularly low probability of marrying subsequently, although there is no evidence that AFDC recipients have lower expectations of marriage. In addition, we find no evidence that stigma associated with nonmarital childbearing plays an important role in this process or that the demands of children significantly reduce unmarried mothers’ time for marriage market activities.     

Good marriages gone bad: Health mismatches as a cause of later-life marital dissolution

This study explores the impact of health status on marital dissolution for couples in late mid-life. A key feature of the empirical framework is that it incorporates the interaction of health between the spouses. This specification allows not only a general test of whether health matters but also a specific test of an important implication of cost-benefit models of marriage dissolution. In particular,cost-benefit models imply that marriages exhibiting a ``health mismatch' (where one partner has substantially better health than the other one) are more likely to get divorced than couples who have similar health (whether good or bad). Using a Cox proportional hazards model, we test this hypothesis by estimating the impact of different spousal health combinations on the probability of marital dissolution (as indicated by separation). Data are taken from four waves of the Health and Retirement Study (1992–1998) and consist of 4,241 couples where at least one spouse is between the ages of 51 and 61 in 1992. We do find evidence for the health mismatch hypothesis, but only among couples in which both couples report their marriages to be very satisfying. Among other couples, no effect is found. This suggests that health is of minor consequence for already unhappy couples, but health mismatches pose a significant risk of dissolution to happy couples within this age cohort, possibly because of the unexpected nature of poor healthat a relatively young age.     

Socio-economic status and divorce in first marriages in Finland 1991-93

Abstract. Various studies report an inverse association between socio-economic status and the risk of marital disruption. Using register-based follow-up data on first marriages in Finland intact at the end of 1990 and divorces in 1991-93 (n=21 309), this study aimed at gaining a better understanding of socio-economic differentials in divorce risk by disentangling the influences of various aspects of the socio-economic status of the spouses. Indicators of socioeconomic status include each spouse's education, occupational class, economic activity, and income as well as housing tenure and housing density. When examined individually, divorce risk was inversely associated with socio-economic status for all its various indicators except wife's income. All of these factors had an independent effect on divorce risk. The effect was, however, weak for the spouses' occupational rankings and housing density, and it was positive for the wife's income. Given the multifaceted nature of these socio-economic differentials, it appears unlikely that one single explanation could account for them all.     

The age at first birth and timing of the second in Costa Rica and Guatemala

This paper explores the relationship between the age at first birth and the timing of subsequent fertility in Costa Rica and in four rural villages and two urban areas of Guatemala. The results indicate that, for Costa Rica, the age at first birth is significantly related to the tempo of subsequent births, and that this association, at least for the interval to second birth, remains significant when socio-economic factors and marital status at the time of first birth are held constant. While the results suggest that the age at first birth is related to timing of the second in the Guatemalan sample as well, the association is weaker and less consistent than in Costa Rica.     

Wife or frau,women do worse: A comparison of men and women in the United States and Germany after marital dissolution

Longitudinal data from the Panel Study of Income Dynamics and the German Socio-Economic Panel show that in the Federal Republic of Germany, women experience even sharper drops in economic status immediately after a marital split than in the United States, while German and American men fare about the same. German social policy does little to reduce the disparities.     

A reconsideration of the economic consequences of marital dissolution

A close look at the income flows in the years following a divorce or separation reveals marked differences in the distribution of effects. The economic consequences of divorce are especially adverse for women. In most cases, children remain with the mother, who usually has considerably lower potential labor market earnings than her former husband, partly because her responsibilities for the children are likely to reduce her labor supply and may have limited her past human capital investments. Alimony and child support are the principal mechanisms for transfers from the ex-husband to the ex-wife, but payments are rarely frequent or sizeable enough to make up for an appreciable amount of the labor income lost through the departure of the ex-husband. Human capital investments on the part of the mother have a modest effect on her economic situation in the years following the divorce. Most men who divorce or separate are immediately better off because they retain most of their labor incomes, typically do not pay large amounts of alimony and child support to their ex-wives, and no longer have to provide for the level of needs associated with their former families. Much more important than growth in the ex-wife's own labor income is the role of a new husband's labor income upon her remarriage. More than half of the white women remarry within five years following a divorce or separation; the comparable fraction for black women is less than half. An interesting question is whether the currently unmarried would enjoy the same kind of economic benefits, were they to remarry, as women who have remarried. Estimates from a model of the new husband's labor income, adjusted for selection bias inherent in the process of remarriage, indicate that the currently unmarried would probably not gain equal benefits if they were to remarry. The expected labor income of potential husbands of black women averages only about $5000--a modest amount when compared with the alternatives available to these women.     

The influence of first generation fertility and economic status on second generation fertility

This paper examines the impact of parental economic status and family size on the actual and expected fertility of adult children using longitudinal data from two generations of families participating in the Panel Study of Income Dynamics. There was a modest positive relationship between first generation family size and second generation fertility. More importantly, the ideal family size of the parental family was more closely related to fertility behavior and plans in the second generation than was actual parental family size. In addition, the data revealed the hypothesized negative correlation between parental financial status and second generation fertility behavior and plans. Several mechanisms which could produce the correlation between parental characteristics and the fertility of their children are explored.The analysis reported in this paper was supported by Contract NO1-HD-42856 from the National Institute for Child Health and Human Development, Center for Population Research.

The demographics of same-sex marriages in Norway and Sweden

The present study investigates the demographics of same-sex marriages--that is, registered partnerships-in Norway and Sweden. We give an overview of the demographic characteristics of the spouses of these partnerships, study patterns of their divorce risks, and compare the dynamics of same-sex couples with those of heterosexual marriages. We use longitudinal information from the population registers of the two countries that cover all persons in partnerships. Our demographic analyses include information on characteristics such as age, sex, geographic background, experience of previous opposite-sex marriage, parenthood, and educational attainment of the partners involved. The results show that in many respects, the distributions of married populations on these characteristics differ by the sex composition of the couples. Patterns in divorce risks are rather similar in same-sex and opposite-sex marriages, but divorce-risk levels are considerably higher in same-sex marriages. The divorce riskforfemale partnerships is double that for male partnerships.     

Intermarriage patterns and social cohesion among first, second and later generation Australians

Studies of ethnic intermarriage in Australia have found that group size, residential segregation, and religious homogeneity, as well as social distance from the dominant (Anglo) cultural group, are important factors determining the likelihood of ethnic intermarriage. However, studies to date have predominantly focused on the first generation, and have less to say about interethnic marriages among members of the second and later generations. This paper analyses marriage patterns across immigrant generations, focusing on specific European ancestries: German, Dutch, Greek, Italian, Polish and Hungarian, contrasted with members of the dominant group. The results reveal strong effects of ancestry, immigrant generation, cross-generational preferences, and intergroup exchanges, as well as a few disjunctions reflecting discontinuities in the history of settlement among different immigrant groups. The results also show that social distance is important in determining the likelihood of intermarriage, as well as the cohesiveness of ethnic groups across generations.     

The effect of marital status at first birth on marital dissolution among adolescent mothers

The sequencing of marriage and first birth was expected to play an important role in the stability of marriage among adolescent mothers. We hypothesized that adolescent women who married prior to conception would have the lowest rates of marital disruption, followed by those who married between conception and birth. Adolescent women who gave birth prior to marriage were expected to suffer the highest rates of marital dissolution. The results provide partial support for our hypotheses. There is little difference in the probability of separation between adolescent mothers who had a postmarital conception and those who had a premarital conception but married before the birth. Having a premarital birth, however, significantly increases the probability of marital dissolution. We also hypothesized that marital status at first birth would have less effect on the probability of marital dissolution for blacks than for whites. This, too, is generally supported by our findings. Among black females, those with a premarital birth are the first to suffer a marital disruption, but by the end of ten years there is little difference in the probability of separation among the three marital status groups. In contrast, among white females, those with a premarital birth are the first to experience a disruption, and this differential persists over all subsequent marriage duration intervals. Thus, the sequencing of marriage relative to birth has similar short term effects for whites and blacks, but the effect for blacks is evident only in the short term. Ten years after the marriage, black adolescent mothers have similar rates of marital stability regardless of the sequencing of marriage. This is consistent with the findings of previous research and with our hypothesis; with the black family pattern of lower rates of marriage, higher rates of illegitimacy and higher divorce rates, the sequencing of marriage has no long lasting consequences on marital stability. Finally, our predicted decline in the effect of marital status at first birth over historical time also finds partial support. For white females there has been a change in the effect of marriage-first birth sequencing on separation over time. In the period encompassed by the women in our study, white adolescent mothers who married subsequent to the birth have been the most likely to experience a separation at all marriage duration intervals, but this differential narrows as age at interview declines. Among black females there has been no change in the effect of a premarital birth over time.(ABSTRACT TRUNCATED AT 400 WORDS)     

Birth month,school graduation,and the timing of births and marriages

We investigated the timing of fertility and marriage in Sweden using exogenous variation in the age at school graduation that results from differences in birth month. Our analysis found that the difference of 11 months in the age at leaving school between women who were born in two consecutive months, December and January, implies a delay in the age at first birth of 4.9 months. This effect of delayed graduation also persists for the timing of second births and first marriages, but it does not affect completed fertility or the overall probability of marriage before age 45. These results suggest the existence of a relatively rigid sequencing of demographic events in early adulthood, and the age at graduation from school emerges as an important factor in determining the timing--but not the quantum--of familyformation. In addition, these effects point to a potentially important influence of social age, defined by an individual's school cohort, instead of biological age. The relevance of social age is likely due to social interactions and peer-group influences exerted by individuals who are in the same school cohort but are not necessarily of the same age.     

A probability sample of gay males

Data are presented from a national probability sample of males interviewed by telephone and asked their sexual orientation. Of these males 3.7 percent reported that they were homosexual or bisexual. Homosexual/bisexual men were compared with heterosexual ones on the demographic variables. This sample produced larger numbers in those groups which appear to be underrepresented in the usual samples drawn from the gay world. These groups include those with little education, married men, older men, minorities, and those living in small towns. It is suggested that probability samples which do not draw directly or heavily from the gay world for homosexual respondents obtain a broader sampling of those having homosexual feelings or behaviors.     

A sequential probability model of fertility patterns

The present paper analyses the fertility histories of a sample of women within a stochastic framework. Recognising the sequential nature of reproductive decisions, the probability that a birth will occur at any given date is related to the realisations of past decisions and to all new information accrued since the last decision date, as well as to the characteristics of the potential mother. Time series are combined with survey data to provide information about the changing economic environment facing all women in the sample. The results of the analysis show the effects of wage rates, child benefits and various personal characteristics on birth probability profiles. The conclusions of the econometric analysis are related to existing theory and to the results of other empirical studies of the economic factors affecting the timing and spacing of births.Thanks are due to Ermisch, Jurgen Doornik and anonymous referees for helpful comments, to Mrs Su Spencer for careful typing and also to the ESRC Data Archive for making available the data.

A probability mixture model of completed parity

This research was designed to find a probability model that would adequately describe completed parity for women in populations characterized by high fertility combined with high zero parity. A negative binomial mixture distribution was adapted for this purpose. The form of this distribution suggests the hypothesis that human populations consist of two subgroups of women with respect to completed parity, defined according to whether they do or do not produce viable offspring. Results of the present research further suggest that the proposed distribution for completed parity has general applicability across human populations, whether they are of a high or low fertility type, and whether they have a high or low zero parity.     

International marriages in South Korea: The significance of nationality and ethnicity

International marriage has increased drastically in South Korea in recent years, and by 2005, 13.6 per cent of marriages involved a foreign spouse. The purpose of this study is twofold: to explore the demographic demand and supply of foreign spouses in the marriage market in South Korea, and to examine how social positions of foreign wives vary by their place in the marriage market as determined by their nationality and ethnicity. Data show that the demand for foreign spouses is particularly strong among rural never-married and urban divorced Korean men. Among foreign wives, Chinese, especially Korean Chinese, tend to marry divorced Koreans, partly because many of them have also been married before. The Korean Chinese are the most autonomous among five groups of foreign wives examined, showing the highest rates of Korean citizenship, divorce-separation, and employment. Southeast Asian women tend to marry rural never-married men, and they are the most adaptive to the host society in the way they show among the highest rates of Korean citizenship and employment (after controlling for their poor Korean proficiency and short duration in Korea). Their divorce-separation rate is the lowest regardless of such control. This study demonstrates that marriage migrants adaptation to the host society differs significantly by nationality and ethnic origin.     

The incidence of divorce within cohorts of American marriages contracted since the civil war

The proportion of marriages that end in divorce can be estimated from vital registration or from census data. The former source suggests considerably higher levels of divorce than does the latter. A new series, combining the two sources, is presented for annual marriage cohorts back to 1867. Actual experience to 1970 is traced and a projection beyond that point is made for cohorts with incomplete divorce histories. The cohort divorce series moves steadily upwards and shows much less variability than an equivalent series of period divorce rates. Factors related to high divorce within a cohort are armed service mobilization and high unemployment rates in the year of marriage, and slow national economic growth between pre- and post-marital periods.     

A probability model applicable to the study of inter-live birth intervals and random segments of the same

Abstract This paper deals with an analytical study of two types of birth intervals, viz. 'closed intervals' and 'open intervals' through the application of simple probability theory. The 'closed interval' stands for the time interval between two successive live births of a woman, and the 'open interval' denotes the interval between the date of last live birth and the date of survey for a married woman in the reproductive age group surveyed at a point of time. The study considers the 'closed interval' as the sum of independent random variables, each representing a particular component like post-partum amenorrhea, waiting time in the susceptible state, etc. Approximations to the patterns of distributions of these component random variables are made from the available data collected in fertility surveys at Gandhigram. The 'open interval' for any parity is studied separately for two different (mutually exclusive) categories of women, viz. those who have at least one more live birth at some time or other during their reproductive period and those who cease childbearing. In the first case the 'open interval' is considered as a random segment or partition of the corresponding 'closed interval'; in the second as a random segment of the interval between the date of birth of the last child and date at which the woman attains 45 years of age. The mean and variance of the 'open interval' is obtained separately in each case, and the moments of the 'open interval' distribution for women chosen at random from the population are obtained as an appropriate mixture of the two types.
