This is a study of the employment patterns of American wives in relation to the composition of their families. The data are taken from the 1960 United States Census, both from published tabulations and the 1/1000 sample. The population studied is non-Negro, non-farm, married, husband present women who are under the age of sixty. The methods of analysis used include the comparison of employment rates among subpopulations and a dummy variable regression technique. Aspects of family composition studied include age of the youngest child (in single years in order to determine whether there are discontinuities in the rates of employment when youngest children enter school, etc.), number of children in the family, and the presence of other relatives in the family. The paper concludes with a discussion of the meaning of family status differentials in employment including differential preferences for employment, differential fertility experience, and differential demands on the mother’s time. Some discussion of the use of cross section data of this sort to infer life cycle patterns of employment is included.  相似文献

In September 2002, a technical working group met to resolve previously published inconsistencies across national surveys in trends in activity limitations among the older population. The 12-person panel prepared estimates from five national data sets and investigated methodological sources of the inconsistencies among the population aged 70 and older from the early 1980s to 2001. Although the evidence was mixed for the 1980s and it is difficult to pinpoint when in the 1990s the decline began, during the mid- and late 1990s, the panel found consistent declines on the order of 1%-2.5% per year for two commonly used measures in the disability literature: difficulty with daily activities and help with daily activities. Mixed evidence was found for a third measure: the use of help or equipment with daily activities. The panel also found agreement across surveys that the proportion of older persons who receive help with bathing has declined at the same time as the proportion who use only equipment (but not personal care) to bathe has increased. In comparing findings across surveys, the panel found that the period, definition of disability, treatment of the institutionalized population, and age standardizing of results were important to consider. The implications of the findings for policy, national survey efforts, and further research are discussed.  相似文献

In the United States, married people have better outcomes on a variety of measures of wellbeing than do single persons. People who participate in religious activities show similar advantages relative to those who have no religious involvement. This article présents a comparative analysis of these two social institutions: marriage and religion. A critical review of the literature on how religious involvement and being married affect a range of child and adult outcomes provides evidence of generally positive effects. Religion and marriage have an impact on many of the same domains of life, and there are remarkable similarities in the mechanisms through which they exert an influence.  相似文献

Effects of childbearing on women's mortality and the implications of family planning programs in reducing these effects are examined in a 20‐year prospective study of more than 2,000 women in Matlab, Bangladesh. Maternal mortality is defined as a death occurring in the six weeks after childbirth. But childbearing may affect women's survival beyond this brief period. Additional hypotheses considered relate to 1) cumulative exposure to childbearing, whether measured by parity or pace of childbearing, 2) age at first birth, and 3) effects beyond the reproductive ages. The results offer no support to cumulative exposure hypotheses, showing no link between parity or pace of childbearing and mortality risk. Instead, we identify an extended period of heightened mortality risk associated with each birth—the year of the birth and the two subsequent years. Family planning programs, by reducing the number of children and therefore a woman's exposure to extended maternal mortality risk, potentially increase survival. Research is needed to identify and address the specific causes of extended maternal mortality risk so that appropriate ameliorative programs may be developed.  相似文献

Divorce, nonmarital childbearing, and cohabitation are reshaping family experience in the United States. Because of these changes, our traditional definitions of families decreasingly capture the social units of interest. We have noted how a significant proportion of officially defined single-parent families actually are two-parent unmarried families. The present paper expands on this perspective with respect to stepfamilies. We must broaden our definition of stepfamilies to include cohabitations involving a child of only one partner, and must recognize the large role of nonmarital childbearing in the creation of stepfamilies. We find that cohabitation and nonmarital childbearing have been important aspects of stepfamily experience for at least two decades, and that this is increasingly so. To define stepfamilies only in terms of marriage clearly underestimates both the level and the trend in stepfamily experience: when cohabitation is taken into account, about two-fifths of all women and 30% of all children are likely to spend some time in a stepfamily.  相似文献

This study (1) assessed whether parent health mediated associations between exposures to the 2010 BP Deepwater Horizon oil spill (BP-DHOS) and child health, and whether child health mediated associations between BP-DHOS exposures and parent health; and (2) assessed bidirectional longitudinal associations between parent health and child health following the BP-DHOS. The study used three waves of panel data (2014, 2016, and 2018) from South Louisiana communities highly impacted by the BP-DHOS. Parents with children (aged 4–18 at the time of the interview) were interviewed based on a probability sample of households. Focal measures included economic and physical BP-DHOS exposures, self-reported parent health, and parent-reported child health. Health measures were gathered at three time points. The analyses included mediation analysis and estimating and comparing effect sizes of longitudinal cross-lagged effects between parent health and child health. Results showed that parent health partly mediated associations between BP-DHOS exposures and child health, and that child health partly mediated associations between BP-DHOS exposures and parent health. Paths from prior waves of parent health to subsequent waves of child health were positive and statistically significant as were paths from prior waves of child health to subsequent waves of parent health. The differences in size of the child-to-parent health effects and the parent-to-child health effects were not statistically significant. This study’s results extend evidence for the post-disaster effect of parent health on child health and the effects of child health on parent health. These findings support the contention that harm to the health of one’s family member following disasters operates as a form of resource loss deleterious to one’s health.

The support systems that are used across the life cycle by women who become widowed were investigated in terms of (a) their frequency of use, and (b) problems for which support services were not seen as being available. In-depth interviews with 298 widowed women indicate relatively little use of organized social services for personal problems. In contrast, family and local doctors were called upon to help with a wide range of personal and economic problems. Many women had problems for which they perceived little or no help as being available in the community. Expectations of ‘front line’ professionals such as doctors, teachers and bankers for help and consultation were frequently not met. Implications of these findings for support systems are discussed.  相似文献
