Family formation in the United States has changed dramatically: marriage has become less common, nonmarital cohabitation has become more common, and racial and economic inequalities in these experiences have increased. We provide insights into recent U.S. trends by presenting cohort estimates for people born between 1970 and 1997, who began forming unions between 1985 and 2015. Using Panel Study of Income Dynamics data, we find that typical ages at marriage and union formation increased faster across these recent cohorts than across cohorts born between 1940 and 1969. As fewer people married at young ages, more cohabited, but the substitution was incomplete. We project steep declines in the probability of ever marrying, declines that are larger among Black people than White people. We provide novel information on the intergenerational nature of family inequalities by measuring parental income, wealth, education, and occupational prestige. Marriage declines are particularly steep among people from low-income backgrounds. Black people are overrepresented in this low-income group because of discrimination and opportunity denial. However, marriage declines are larger among Black people than White people across parental incomes. Further, most racial differences in marriage occur among people from similar socioeconomic backgrounds. Family inequalities increasingly reflect both economic inequalities and broader racial inequalities generated by racist structures; in turn, family inequalities may prolong these other inequalities across generations.

Introduction: cervical cancer is a leading cause of death among Nigerian women. Women often require spousal support before attending cervical cancer screening services. This study assessed married men´s knowledge and attitude towards male involvement in cervical cancer screening of their wives., Methods: a cross-sectional study using a mixed methods approach was conducted among 245 married men in Izzi, Local Government Area of Ebonyi State, South-East Nigeria. Quantitative data collected using structured, interviewer-administered questionnaires and qualitative data from focus group discussions were triangulated. Data analysis was done using IBM SPSS version 20. Qualitative findings were analysed using thematic analysis., Results: the mean knowledge of cervical cancer was 2.06±0.55. Only 2.9% of the respondents had adequate knowledge of risk factors for cervical cancer. Up to 89.8% were willing to approve screening for their spouses. Majority (76.3%) considered screening important in cervical cancer prevention, while 91.4% were willing to pay for the screening test. Most of them exhibited patriarchal tendencies and insisted that their wives must obtain their consent before screening as depicted by the statement "It is what I tell her that she will do". Previous spousal screening was a predictor of good knowledge (OR = 10.94, 95% CI = 2.44-48.93; P=0.002)., Conclusion: married men in this study had poor knowledge of cervical cancer. However, they were willing to support cervical cancer screening conditional on their pre-information and consent. Awareness creation activities on cervical cancer screening should incorporate active engagement of husbands in order to promote screening uptake by their wives., Competing Interests: The authors declare no competing interests., (Copyright: Ijeoma Nkem Okedo-Alex et al.)

Family structure changes experienced by children are likely to shape their transitions into young adulthood, including the formation of their own romantic relationships. This study examined links between children's family structure trajectories from childhood through adolescence and their timing of entry into cohabitation as young adults, a transition with implications for future relationship instability through adulthood. Repeated measures latent class analysis identified configurations of family structures and family structure changes from birth through age 15 among 10,706 young people in the National Longitudinal Survey of Youth, 1979 Children and Young Adults. A Cox proportional hazard model then used the resulting classes to predict timing into cohabitation over the period from age 15 to age 38. Both timing of family structure transitions and the type of transitions (e.g., early transitioning into a stepfamily home) were associated with earlier entry into cohabitation. Notably, links between family structure trajectories and the timing of cohabitation differed by gender and race/ethnicity (Latinx, African American, White), such as a faster entry into cohabitation by women who experienced early entry into stepfamily structures. Regardless of gender, Latinx and White young adults were faster to enter into cohabitation if they lived in a stepfamily structure during early childhood.

Marriage involving a man and a woman is a universal social institution, but its practices vary among cultures. In Nigeria, a marriage is recognized after gifts are given, and a bride price is paid by the groom's family to the bride's family. Understanding the bride price will reduce the challenges women face in their marital homes. Women's autonomy is important for them to address matters affecting their health. We examined married Ikwerre women's perspectives on bride price and its impact on their autonomy using qualitative methods. From December 2014 to March 2015, 34 in-depth interviews and six focus group discussions were conducted with married Ikwerre women. Participants reported that patriarchy and a culture of absolute respect for men, not the bride price, was the reason for women's diminished autonomy. Participants noted that payment of the bride price was critical for validating marriage to give women respectable status in society as wives. Patriarchal rule and the demand for absolute respect for men need to be addressed in the Ikwerre culture. A woman's capability to address her health needs and use health care is largely dependent on her ability to act autonomously. Thus, educational interventions to enable women's decision-making are critical.

A woman's lack of or limited reproductive autonomy could lead to adverse health effects, feeling of being inferior, and above all being unable to adequately care for her children. Little is known about the reproductive autonomy of married Ikwerre women of Rivers State, Nigeria. This study demonstrates how Ikwerre women understand the terms autonomy and reproductive rights and what affects the exercise of these rights. An exploratory research design was employed for this study. A semi-structured interview schedule was used to conduct thirty-four in-depth interviews and six focus group discussions with purposively sampled educated, semi-educated, and uneducated Ikwerre women in monogamous or polygynous marriages. The collected data was analysed qualitatively with MAXQDA 11 using open and axial coding. The interviews and focus group responses reveal a low level of awareness of autonomy and reproductive rights amongst the Ikwerre women in Nigeria. While some educated women were aware of their reproductive rights, cultural practices were reported to limit the exercise of these rights. Participants reported that Ikwerre culture is a patriarchal one where married women are expected to submit and obey their husbands in all matters; and a good married woman according to Ikwerre standard is one who complies with this culture. Women's refusal of sexual advances from their husbands is described as not being acceptable in this culture; and hence rape in marriage is not recognized in Ikwerre culture. Education and awareness creation on the importance of women's reproductive autonomy could improve their reproductive rights and autonomy in marital settings. Overcoming the patriarchal aspects of Ikwerre culture-for example, the greater value placed on male children than female children and treating women as incompetent individuals-is necessary to promote gender equality as well as help improve women's reproductive autonomy.

This study sheds light on the development of family structures in a polygamous context with a particular emphasis on wife order, and offers an explanation for the association between outcomes of children and the status of their mothers among wives based on observable maternal characteristics. In a simple framework, I propose that selection into rank among wives with respect to female productivity takes place: highly productive women are more strongly demanded in the marriage market than less productive women, giving them a higher chance of becoming first wives. Furthermore, productivity is positively associated with a wife's bargained share of family income to be spent on consumption and investment for herself and her offspring because of greater contributions to family income and larger outside options. The findings are empirically supported by a positive relationship between indicators of female productivity and women's levels of seniority among wives, and by a concise replication of existing evidence relating wife order to children's educational outcomes in household survey data from rural Ethiopia.

Japanese older people experienced drastic changes in family structure and values after World War II at different life stages by birth cohorts. We examined how linkages between different types of social ties and life satisfaction (LS) vary across cohorts, in conjunction with age and survey year differences. Data from face-to-face interviews conducted in 1987, 1999, and 2012 with a nationally representative sample of older Japanese (N = 4,917) were analyzed. The participants were members of 4 birth cohorts (C1: 1901-1912, C2: 1913-1924, C3: 1925-1936, C4: 1937-1949), categorized into 6 groups based on cohort and age at time of measurement (young-old [YO]: 63-74; old-old [OO]: 75-86): C1OO, C2YO, C2OO, C3YO, C3OO, and C4YO. Effects of social networks on LS among the 6 groups were compared simultaneously and separately by gender using the Amos software. There were significant cohort variations in the linkages between family network and LS. The positive association between being married and LS was stronger for later cohorts (C3, C4) among men, whereas that of co-residence with a child and LS was stronger for the earlier cohorts (C1, C2) among women. Moreover, the positive association between meeting with nonfamily members and LS increased from 1987 to 2012 among women, indicating a period effect over a cohort effect. The effects of being married and participation in community groups on LS also changed with age. Our results suggest that linkages between social relations and LS should be interpreted within the context of individual and social changes over time., ((c) 2015 APA, all rights reserved).)

Informed by socioecological and dyadic approaches to understanding marriage, the current study examined the patterning of gender-typed attributes among 120 Mexican immigrant opposite sex couples and the subsequent links with spouses' reports of marital satisfaction. Latent profile analysis (LPA) was used to identify typologies of couples based on spouses' self-reported masculine and feminine attributes. Three couple profiles were identified: (a) Androgynous Couples, (b) Undifferentiated Couples, and (c) Mismatched Couples. Results from a mixed model ANCOVA showed profile differences in couples' marital satisfaction based on profile membership, suggesting that spouses in the Undifferentiated Profile were the least satisfied. Findings illustrate a lack of gender-typing at the individual and couple levels that challenge stereotypical and patriarchal depictions of Latino marital relationships and propose a more complex understanding of Mexican-origin spouses' gender-typed attributes than has yet been portrayed in the literature. The finding that couples with 1 androgynous partner (i.e., wives in the Mismatched Profile) reported similar levels of marital satisfaction to couples in the Androgynous Profile offers additional insights regarding how these qualities operate under the unique socioecological niches that Mexican immigrant couples inhabit-contexts that may place demands on spouses that challenge gendered and culturally bound depictions of marriage., ((c) 2015 APA, all rights reserved).)

Adding to the growing literature explicating the links between romantic relationships and health, this study examined how both couple-level characteristics, particularly union type (e.g., dating, cohabiting, or marriage) and interracial pairing, and interpersonal characteristics (e.g., partner strain and support), predicted young adults' physical and mental health. Using dyadic data from a sample of 249 young, primarily Black couples, we hypothesized and found support for the importance of couple-level context, partner behavior, and their interaction in predicting health. Interracial couples (all Black/non-Black pairings) reported worse health than monoracial Black couples. Union type, however, did not directly predict health but was a significant moderator of partner strain. That is, the negative association between partner strain and self-reported health was stronger for cohabiting and married couples versus their dating counterparts, suggesting that coresidence, more so than marital status, may be important for understanding partner effects on physical health. For psychological distress, however, partner support proved equally beneficial across union types.

In many parts of Asia, the Middle East and North Africa, women and children are so undervalued, neglected, abused, and so often killed, that sex ratios are now strongly male biased. In recent decades, sex-biased abortion has exacerbated the problem. In this article I highlight several important insights from evolutionary biology into both the origin and the severe societal consequences of "Asia's missing women", paying particular attention to interactions between evolution, economics and culture. Son preferences and associated cultural practices like patrilineal inheritance, patrilocality and the Indian Hindu dowry system arise among the wealthy and powerful elites for reasons consistent with models of sex-biased parental investment. Those practices then spread via imitation as technology gets cheaper and economic development allows the middle class to grow rapidly. I will consider evidence from India, China and elsewhere that grossly male-biased sex ratios lead to increased crime, violence, local warfare, political instability, drug abuse, prostitution and trafficking of women. The problem of Asia's missing women presents a challenge for applied evolutionary psychology to help us understand and ameliorate sex ratio biases and their most severe consequences.

Child mortality, defined here as mortality under age five, is not evenly distributed but found in clusters. In a contemporary polygamous population in Ghana with extended families, we separate clustering at the parental and household levels, which are often overlapping and inseparable in other historical studies. For eight years, we followed 28,994 individuals, including 9,288 children under the age of five, in 1,703 households. We identified four determinants that had a significant effect on child mortality: sex of the child, age of the child, drinking source, and socioeconomic status. After correcting for these determinants, we still identified significant clustering of child mortality at the level of the village (covariance [cov] = 0.02, p = .04), household (cov = 0.14, p = .003), father (cov = 0.24, p = .001), and mother (cov = 0.18, p = .05). The present data provide clues regarding the levels at which to look for unidentified determinants of child mortality and suggest that the importance of the father could be larger than previously thought.

This article integrates (1) research in the historical dynamics of state societies relating group solidarity and group expansion to cultural frontiers, (2) comparative research in anthropology relating matrilocality to a particular variety of internal politics and a particular form of warfare, and (3) interdisciplinary reconstructions of large-scale "demic expansions" and associated kinship systems in prehistory. The argument is that "metaethnic frontiers," where very different cultures clash, are centers for the formation of larger, more enduring, and more militarily effective groups. In small-scale non-state societies, the major path toward the formation of such groups is the establishment of cross-cutting ties among men. This often involves the adoption of matrilocal norms. The current distribution of matrilocality and matrilineality around the world may be partly a residue of major demic expansions in prehistory involving matrilocal tribes. This hypothesis is evaluated with a range of evidence, including information regarding the spread of two language families, Bantu and Austronesian.

This paper presents a comparison of social kinship (patrilineage) and biological kinship (genetic relatedness) in predicting cooperative relationships in two different economic contexts in the fishing and whaling village of Lamalera, Indonesia. A previous analysis (Alvard, Human Nature 14:129-163, 2003) of boat crew affiliation data collected in the village in 1999 found that social kinship (patrilineage) was a better predictor of crew affiliation than was genetic kinship. A replication of this analysis using similar data collected in 2006 finds the same pattern: lineage is a better predictor than genetic kinship of crew affiliation, and the two together explain little additional variance over that explained by lineage alone. However, an analogous test on food-sharing relationships finds the opposite pattern: biological kinship is a better predictor of food-sharing relationships than is social kinship. The difference between these two cooperative contexts is interpreted in terms of kin preferences that shape partner choice, and the relative autonomy with which individuals can seek to satisfy those preferences. Drawing on stable matching theory, it is suggested that unilineal descent may serve as a stable compromise among multiple individuals' incongruent partner preferences, with patriliny favored over matriliny in the crew-formation context because it leads to higher mean degrees of relatedness among male cooperators. In the context of food-sharing, kin preferences can be pursued relatively autonomously, without the necessity of coordinating preferences with those of other households through the institution of lineage.

When we have asked Hadza whether married couples should live with the family of the wife (uxorilocally) or the family of the husband (virilocally), we are often told that young couples should spend the first years of a marriage living with the wife's family, and then later, after a few children have been born, the couple has more freedom--they can continue to reside with the wife's kin, or else they could join the husband's kin, or perhaps live in a camp where there are no close kin. In this paper, we address why shifts in kin coresidence patterns may arise in the later years of a marriage, after the birth of children. To do so, we model the inclusive fitness costs that wives might experience from leaving their own kin and joining their husband's kin as a function of the number of children in their nuclear family. Our model suggests that such shifts should become less costly to wives as their families grow. This simple model may help explain some of the dynamics of postmarital residence among the Hadza and offer insight into the dynamics of multilocal residence, the most prevalent form of postmarital residence among foragers.

Dispersal of individuals from their natal communities at sexual maturity is an important determinant of kin association. In this paper we compare postmarital residence patterns among Pumé foragers of Venezuela to investigate the prevalence of sex-biased vs. bilateral residence. This study complements cross-cultural overviews by examining postmarital kin association in relation to individual, longitudinal data on residence within a forager society. Based on cultural norms, the Pumé have been characterized as matrilocal. Analysis of Pumé marriages over a 25-year period finds a predominant pattern of natalocal residence. We emphasize that natalocality, bilocality, and multilocality accomplish similar ends in maximizing bilateral kin affiliations in contrast to sex-biased residential patterns. Bilateral kin association may be especially important in foraging economies where subsistence activities change throughout the year and large kin networks permit greater potential flexibility in residential mobility.

This article is a close reading of Gustave D'Eichthal and Ishmayl Urbain's Lettres sur la race noire et la race blanche (1839), written during the decade prior to the "second" French emancipation in 1848. The article argues that the hierarchical gendering of race described in the letters is reflective of metropolitan concerns about potential for social disorder accompanying slave emancipation in the French colonies. In arguing for social reconciliation through interracial marriage and its offspring, the symbolically charged figure of the mulatto, the authors deployed gendered and familial language to describe a stable post-emancipation society.

A growing number of less-developed countries have introduced conditional cash transfer programs in which funds are targeted to women. Economic models of the family suggest that these transfer programs may lead to marital turnover among program beneficiaries. Data from the experimental evaluation of the PROGRESA program in Mexico is used to provide new evidence on the short-run impacts of targeted transfers on couples' union dissolution and individuals' new union formation decisions. We find that, although the overall share of women in union does not change as a result of the program, marital turnover increases. Intact families eligible for the transfers experienced a modest (0.32 percentage points) increase in separation rates, with most of the effect concentrated among young and relatively educated women households. In contrast, young single women with low educational attainment levels experienced a substantial increase in new union formation rates. The marital transition patterns are consistent with the workhorse economic model of the marriage market-individuals with the greatest prospects to start new unions and those who may become more attractive in the marriage market are more likely to transition out of existing relationships and form new ones.

Objective: Several recent studies have investigated the consequences of racial intermarriage for marital stability. None of these studies properly control for first-order racial differences in divorce risk, therefore failing to appropriately identify the effect of intermarriage. Our article builds on an earlier generation of studies to develop a model that appropriately identifies the consequences of crossing racial boundaries in matrimony., Methods: We analyze the 1995 and 2002 National Survey of Family Growth using a parametric event-history model called a sickle model. To appropriately identify the effect of interracial marriage we use the interaction of wife's race and husband's race., Results: We find elevated divorce rates for Latino/white intermarriages but not for black/white intermarriages. Seventy-two percent of endogamous Latino marriages remain intact at 15 years, but only 58 percent of Latino husband/white wife and 64 percent of white husband/Latina wife marriages are still intact., Conclusions: We have identified an important deficiency in previous studies and provide a straightforward resolution. Although higher rates of Latino/white intermarriage may indicate more porous group boundaries, the greater instability of these marriages suggests that these boundaries remain resilient.

Nearly all of today's confident dismissals of the notion of a "post-racial" America address the simple question, "Are we beyond racism or not?" But most of the writers who have used the terms post-racial or post-ethnic sympathetically have explored other questions: What is the significance of the blurring of ethnoracial lines through cross-group marriage and reproduction? How should we interpret the relatively greater ability of immigrant blacks as compared to standard "African Americans" to overcome racist barriers? What do we make of increasing evidence that economic and educational conditions prior to immigration are more powerful determinants than "race" in affecting the destiny of population groups that have immigrated to the United States in recent decades? Rather than calling constant attention to the undoubted reality of racism, this essay asks scholars and anti-racist intellectuals more generally to think beyond "the problem of the color line" in order to focus on "the problem of solidarity." The essay argues that the most easily answered questions are not those that most demand our attention.

We analyze the marriage-market aspects of weight and height in the United States using data from the Panel Study of Income Dynamics on anthropometric characteristics of both spouses. We find evidence of positive sorting in spouses' body mass index (BMI), weight, and height. Within couples, gender-asymmetric trade-offs arise not only between physical and socioeconomic attributes, but also between anthropometric attributes, with significant penalties for fatter women and shorter men. A wife's obesity (BMI or weight) measures are negatively correlated with her husband's income, education, and height, controlling for his weight and her height, along with spouses' demographic and socioeconomic characteristics. Conversely, heavier husbands are not penalized by matching with poorer or less educated wives, but only with shorter ones. Height is valued mainly for men, with shorter men matched with heavier and less educated wives., (Copyright © 2010 Elsevier B.V. All rights reserved.)

In this article, the author focuses on the speculative literalism and typologism in current scholarship to construct a taken-for-granted view, taking issue especially with many points raised in the literature on the subject that have associated fertility rates in Albania more closely with the existence of patriarchal cultural traits. This leads the author to argue that the specific rationale for the myth of many children, high fertility rates, and complex family structures in Albanian context, as elsewhere in patrilineal societies, is an ideological elaboration of patriarchy. Methodologically, the analysis of the standard view of childbearing, based on standard ethnographic methods, traditional historical sources and aggregate demographic data, is aimed to illustrate the inadequacy of the historical-ethnographic paradigm against the available empirical evidence. In turn, understanding how ideological elements are emphasized in cultural activism should lead, against current scholarship claims, to an understanding of the way in which the urgent need for male children must have been to hide away other more troubling reasons.

The physical and ideological boundaries between public and private in early modern Scotland were constantly contested, resulting in a shifting reality of what was public and private. This fluidity has been recognized by historians, but how, when, and why the shifting took place is not as clear. The moral church courts (Kirk Sessions) of Reformation Scotland allow a unique opportunity to begin to understand the largely elusive boundaries between public and private in the early modern era.

The aim of the article is to modify our understanding of the history of middle-class marriage. It draws upon the detailed examination of one Wolverhampton couple's marriage to explore relationships between husbands and wives-and between ex-husbands and ex-wives-in early twentieth-century provincial England. It argues that patriarchal and companionate marriages co-existed alongside one another; that even in patriarchal marriages wives were prepared to seek legal redress for their grievances; and that even in insular and unfashionable regions of the country such as the Black Country the courts, both civil and criminal, policed masculinity and femininity in their assessment of where fault lay.

This article statistically analyzes quantitative data from numerous sources in order to assess changes in marriage patterns, family structure, and rates of social mobility during the period from 1282 to 1494. During this period, three systems of social stratification coexisted -- wealth, political office, and age of family -- but these contending status systems were not consistent in their rankings of families. Each status system was conservative in the sense that elite families at the top of that hierarchy married each other in order to stabilize their position. But because of inconsistency in rankings, contradiction within the elite opened up the Florentine marriage system to widespread upward social mobility by new men. In their own families, successful new men aggressively imitated their economically and politically declining status superiors. Sharp class divisions thereby blurred into continuous and negotiable status gradients. These open-elite patterns of social mobility, present throughout the early Florentine Renaissance, were most extreme during the Albizzi regime, immediately following the Ciompi Revolt.

The harem image has dominated the conceptualizations of the family and the private sphere in the Ottoman empire at the turn of the century. This essay aims to review these conceptualizations and locate family life in both public and private spheres. The main source of inquiry will be the literary writings of Fatma Aliye (1862-1936) who wrote about women, marriage, education, poverty, and slavery. In these works, she outlined common dreams for Eastern and Western women, such as the love and companionship of an honest, monogamous man. These dreams envisioned Muslim women performing a variety of roles and thus transcended the given expectations from the family and from Muslim women as a monolithic category. In this light, this essay seeks to contextualize Aliye's works within the history of the family by evaluating Aliye's views particularly on marriage.

Using the controversy surrounding marriage with a deceased wife’s sister that occupied Presbyterian and Congregationalist theologians of the early Republic, this essay explores the eroticization of the sentimental family and the contours and crises of the incest prohibition in the wake of the Revolution. The essay begins by tracing the history of ecclesiastical trials of incestuous marriage in the Presbyterian church, arguing that the failure of the synods and General Assembly to offer definitive judgments of such marriages suggests a tension in the force of a transcendent incest prohibition. Two cases from the late 1820s, in particular, gained national attention in both the theological and secular press, and force the Presbyterian church to explore the legitimacy of their incest prohibition, and exploration that lead, ultimately, to a constriction of the incest prohibition as written in the Westminster confession of Faith. I then turn to the conjunction of kinship, sexuality, and sentiment that animates the texts comprising the controversy and argue that, in an effort to defend an expansive interpretation of the Levitical incest prohibitions these theologians were among the earliest writers to argue that sentimental, affectionate relations between family members were inherently erotic. In this sense, the family becomes the primary site for the deployment of sexuality. Such a concern about the incestuous nature of family relations, in turn, forced theologians to consider the problem of incest in the postlapsarian origins of society.

We perform a content analysis of twenty marriage and family textbooks published between 1950 and 2000 to study how the voluntarily childless are presented in undergraduate courses. Throughout the time period studied, independence, pursuit of a career, and romance were prominent themes in the representation of voluntary childlessness. Other themes emerged specific to each decade - the 1950s portrayed parenthood as a challenge, while the 1990s concentrated on alleviating negative stereotypes of the voluntarily childless.

Purpose: To examine the decision-making processes of husband and wife dyads in matrilineal and patrilineal marriage traditions of Malawi in the areas of money, food, pregnancy, contraception, and sexual relations., Methods: Qualitative grounded theory using simultaneous interviews of 60 husbands and wives (30 couples). Data were analyzed according to the guidelines of simultaneous data collection and analysis. The analysis resulted in development of core categories and categories of decision-making process. Data matrixes were used to identify similarities and differences within couples and across cases., Findings: Most couples reported using a mix of final decision-making approaches: husband-dominated, wife-dominated, and shared. Gender based and nongender based cultural scripts provided rationales for their approaches to decision making. Gender based cultural scripts (husband-dominant and wife-dominant) were used to justify decision-making approaches. Non-gender based cultural scripts (communicating openly, maintaining harmony, and children's welfare) supported shared decision making. Gender based cultural scripts were used in decision making more often among couples from the district with a patrilineal marriage tradition and where the husband had less than secondary school education and was not formally employed., Conclusions: Nongender based cultural scripts to encourage shared decision making can be used in designing culturally tailored reproductive health interventions for couples., Clinical Relevance: Nurses who work with women and families should be aware of the variations that occur in actual couple decision-making approaches. Shared decision making can be used to encourage the involvement of men in reproductive health programs.

Using the first (1995) and third (2001-2002) waves of the Add Health survey, we examine women 's family transitions up to age 24. Only a third of all women marry, and a fifth of those marriages dissolve before age 24. Three out of eight women have afirst birth, with a substantial majority of those births outside of marriage: 66% for whites, 96% for blacks, and 72% for Mexican Americans. Cohabitation is the predominant union form; 59% of women cohabit at least once by age 24. Most cohabitations are short lived, with approximately one in five resulting in a marriage. We summarize the family and relationship experience of women up to age 24 in terms offour categories, each accounting for roughly a quarter of all women. Category 1 has the women who remain single nonparents. Category 2 has the early marriers, women whose marriage is not preceded by a first birth. Category 3 has those who become single parents. Category 4 has the women who cohabit at least once, but who do not marry or have a birth by age 24. The strictly ordered transitions of the 1950s are long gone and have been replaced by a variety of paths to adulthood.

This study examines the reproductive success of men and women in rural Ethiopia as a function of their marital status, specifically by comparing polygamously and monogamously married individuals. In line with predictions from evolutionary theory, polygamy is beneficial to male reproductive success (i.e. producing larger numbers of surviving offspring). The success of polygamously married females depends on wife rank: the first wives of polygamous husbands do better than monogamously married women and much better than second or third wives. These effects are mirrored in child nutritional status: the children of second and third wives have lower weight for height. Due to potential, largely unmeasurable differences in marriageability (quality) between individuals, it was not possible to support a model of either resource-holding polygyny combined with female choice or female coercion into unwanted marriages. First wives of polygamously married men marry at a younger age and attract a higher brideprice, suggesting that both the males and females in the marriage are likely to be of higher quality (due to wealth, family status or some other factor such as beauty). Unions that end up monogamous are likely to be between slightly lower quality individuals; and second and third wives, who marry at the oldest ages and attract the lowest brideprice, may be 'making the best of a bad job'. The relatively long gap between first and second marriages may mean that first wives of highly marriageable males can enjoy considerable reproductive success before their husbands marry again.

Gender bias usually favors males, yet among the matrilineal Gwembe Tonga of Zambia, females appear to receive preferential treatment. It is hypothesized that children in polygynous households will have increased levels of malnutrition due to the dilution of resources. Further, if gender bias is observed, it will favor females. The presence of preferential treatment during preadolescence is assessed by measuring physical status in the household. Monogamous or polygynous status of households is considered in this analysis of 188 children of age 0-10 years. The sample, 63 households from two rural villages, includes 47 females and 49 males in monogamous households and 52 females and 40 males in polygynous households. Comparisons of nutritional status are made with < or =-2.0 SD as indicative of stunting (height-for-age), wasting (weight-for-height), and chronic underweight (weight-for-age). Boys have better nutrition in monogamous households-40.8% stunted and 24.5% underweight compared to 62.5% stunted (P = 0.021), 42.5% underweight (P = 0.036) in polygynous households. Female stunting does not differ significantly by household type (40.4% monogamous, 42.3% polygynous). Low levels of wasting in either sex regardless of household type were observed. Girls have better physical status than boys in polygynous households, thereby supporting our combined hypotheses and demonstrating gender bias in pre-adolescents.

The focus of this work is the analysis of changes in completed family size and possible determinants of that size over time, in an attempt to characterize the evolution of reproductive patterns during the demographic transition. With this purpose in mind, time trends are studied in relation to the mean number of live births per family (as an indirect measure of fertility), using family reconstitution techniques to trace the reproductive history of each married woman. The population surveyed is a Spanish rural community called Lanciego, located at the southern end of the province of Alava (Basque Country). A total of 24,510 parish records of baptisms, marriages and burials made between 1800 and 1969 were examined to obtain the demographic data set. For each reconstituted family, the variables included in the study were the number of live births per family or family size (FAMS), year of marriage (YEAR), age at marriage of both partners (AMAN, AWOM), wife's age at the end of marriage (WEND), duration of marriage (MARD), age at first maternity (A1CH), length of reproductive span (REPS) and number of children dying before their first anniversary (MINF). Through a principal component analysis, three factors were found that explained more than 75% of the total variance. Association of variables in factors I and III was particularly useful in characterizing the variability of mean family size in pre-transitional, transitional and post-transitional cohorts. During demographic transition, a decreasing trend is observed in the variables FAMS, REPS and MINF, while variables AWOM, AMAN, WEND and A1CH show a tendency to increase over the 20th century. Results obtained by multiple regression analysis confirm that the best predictors of family size (dependent variable) were REPS and MINF, which between them explained over 85% of the total variation in FAMS (R2 = 0.853). In Lanciego, birth control seems to be present on the evidence of an increase in age at first maternity and a decrease in age at last parturition, indicating that the beginning of the reproductive span is delayed and its end is brought forward. Interaction between family size and infant mortality is discussed in the light of various hypotheses, including replacement of descendants, the so-called biological effect and the theory of r and k selection.

This study tests the grandmother hypothesis and analyzes the effect of kin propinquity on infant mortality in a 19th century American frontier communal, polygynous population. The study shows that the presence of maternal grandmothers, aunts, uncles, and paternal aunts were significantly associated with increased infant survivorship while grandfathers, paternal grandmothers, and paternal uncles showed little effect. This study has implications for understanding the evolution of a long postreproductive life span, postmarital residential strategies, and behavioral strategies that enhance inclusive fitness.

In Arab and Islamic countries, domestic violence is not yet considered a major concern despite its increasing frequency and serious consequences. Surveys in Egypt, Palestine, Israel and Tunisia show that at least one out of three women is beaten by her husband. The indifference to this type of violence stems from attitudes that domestic violence is a private matter and, usually, a justifiable response to misbehaviour on the part of the wife. Selective excerpts from the Koran are used to prove that men who beat their wives are following God's commandments. These religious justifications, plus the importance of preserving the honour of the family, lead abusers, victims, police and health care professionals to join in a conspiracy of silence rather than disclosing these offences. However, a fair reading of the Koran shows that wife abuse, like genital mutilation and "honour killings" are a result of culture rather than religion.

Background: The levels of consanguinity in human populations are known to be influenced by demographic and geographical factors, and by socio-cultural customs that govern spouse choice. Within the general model applicable to the populations of Western Europe, Galicia (north-west Spain) is a region that is especially interesting, due to its geographical and historical peculiarities that could have conditioned its behaviour pattern with respect to consanguinity., Primary Objective: The object of this paper is to analyse the evolution of the consanguinity structure levels in the rural population of the Bishopric of Lugo (Galicia) during the period 1900-1979., Subjects and Methods: The study covers a total of 752 parishes included in 52 municipalities of the rural area of the Bishopric of Lugo. Of a total of 117,583 marriages in the period studied, 6701 were between biologically related individuals up to the level of second cousins. The percentage of the different types of consanguineous marriages, the consanguinity rates, and the average coefficient of inbreeding of the population was calculated. Also, for the analysis of the temporal variation of consanguinity, version 3.01 of Jandel Scientific's Table Curve program was used., Main Outcomes and Results: The consanguinity rate for the whole of the period is 5.70% and the average coefficient of inbreeding is 2.2477 x 10(-3), values which fall within the observed range for Spanish populations. As for the consanguinity structure, the most frequent types of consanguineous marriages are between second cousins (2.65% of all marriages), but the high proportion of marriages between uncles/nieces or aunts/nephews (0.16%) and first cousins (2.12%) with regard to the total number of marriages should be emphasized. The average value of the M22/M33 ratio is 0.80, and throughout the study period it was above the 0.25 expected in conditions of panmixia. Regarding the evolution of the average coefficient of inbreeding, its annual values fit a polynomial regression curve with one ascending and one descending branch and an inflection point in the year 1919., Conclusions: As in other rural areas of Galicia, the structure of consanguinity in the Bishopric of Lugo is characterized by the high proportion of marriages between uncles/nieces or aunts/nephews and first cousins, a phenomenon which appears to be generalized in the rural populations of northern Spain. It is suggested that the high proportion of uncle/niece marriages that have been found in the population studied are very probably due to the important migratory phenomenon which took place in this region at the end of the 19th century and in the first third of the 20th century.
