Abstract The analysis of changes in childlessness as opposed to structural correlates of childlessness is quite new. Our focus on indicators of such changes called for a macro-analytic framework which would permit the test of changing features of population characteristics and the relationship between structural changes in different population cohorts. An appropriate data set was one that would permit the analysis ofchanging levels ofchildlessness in age cohorts and the changes in population characteristics which would offer possible explanations for the changing childlessness pattern. 相似文献

Summary This paper describes changes in the incidence of marital childlessness among United States women since 1940 and tests a model to explain recent observed trends toward increasing childlessness. Based on U.S. Bureau of the Census sources, data are presented that indicate a substantial increase in childlessness for married women under 30 years of age since 1960. A path model is developed based on previous research on childlessness, in an attempt to explain this change. The model is composed of 1960-70 changes in (1) mean age at first marriage, (2) mean educational attainment, (3) the proportion of women in the labour force, (4) the proportion of women enrolled as students, (5) the incidence of marital disruption, and (6) the proportion of women living in urban environments. Using quarter-year age cohort data derived from the 1960 and 1970 1/100 Public Use Samples the results indicate that a substantial part of the increase in childlessness csn be explained by this model. Particularly important were increased enrolment of married women in education, labour force participation, and mean age of first marriage. The results suggest the relevance of structural changes along with birth expectation attitudes in predicting trends in childlessness in the United States. 相似文献

The thesis of this study is that as a result of increased inequalities in welfare rules, the 1996 welfare reform act not only enhanced incentives for poor families to move but also (and perhaps more important) created disincentives for them to stay in "race to the bottom" states. In testing this thesis, we evaluated the mediating and moderating roles of state economic development and family structure. We merged data from three main sources: the 1996-1999 panel of the Survey of Income and Program Participation, the Urban Institute's Welfare Rules Database, and state economic data from the Bureau of Labor Statistics. Modeling both destination (pull) and departure (push) effects of welfare policy measures and selected covariates in a nested discrete-time event-history migration analysis, we found robust support for the thesis that stringency in state welfare-eligibility and behavior-related rules stimulated interstate out-migration of poor families in the United States. However poor families were not drawn to states with relatively more-lenient welfare rules, although stringency in state welfare dollar benefits inhibited in-migration and state unemployment patterns may have conditioned the migration effects of welfare-reform rules on the choice of destination. Single mothers were not more directly affected by welfare-eligibility and behavior-related rules than were poor married couples. 相似文献

During the last two decades of the twentieth century, Italy, Greece, Spain, Portugal, and Japan were characterized by very
low fertility levels and limited diffusion of the pill, IUD and sterilization for contraceptive purposes. This paradox is
discussed for Italy by revisiting the history of contraception and reproduction during the second half of the twentieth century,
and by using new data for the end of that century and the early twenty-first century. The main results are: (1) it has been
possible to maintain low rates of planned and unplanned fertility without resorting to more effective contraceptive methods
thanks to a careful use ofcoitus interruptus; (2) the pace of diffusion of the pill and IUD was so slow because of the opposition to contraception of the Catholic Church,
a gender system emphasizing traditional male and female roles, and a medical culture that made physicians reluctant to prescribe
the pill for their patients; and (3) the contraceptive patterns of Italian women born after 1960 are more similar to those
of their Western counterparts, although new peculiarities appear, for example, substantial reliance on the condom by people
living as couples as well as sexually active singles. 相似文献

This paper examines the intentions of Dutch males and females with regard to combining paid employment and parenthood. Four models of how couples combine these roles are distinguished. Panel data from a representative survey among Dutch young adults show that the traditional model (the female takes care of the children and the male works full-time) is becoming less popular, whereas the supplementary model (the female takes care of the children and supplements the labor force participation of the male), and the egalitarian model (both partners share paid labor more or less equally) are becoming more popular. The no-child model is preferred by about 10% of the respondents. A multivariate analysis shows that both job characteristics, like the flexibility of working hours, and gender role attitudes are important predictors of intentions with regard to combining family and work roles. 相似文献

This report examines the demographic forces at work in the US that will influence the country's future. A profile of the US population in the mid-1990s reveals that the US is the third most populated countries in the world and one of the fastest growing of the industrialized countries. 70% of this growth is due to natural increase and 30% to immigration. The first topic covered in this report, geographic patterns of growth and change, includes a consideration of regional patterns, population growth by state, residential patterns, and the increase in the number of minorities living in suburban areas. The second topic is the changing age structure, which is characterized by an aging of the population and an increase in the number of children. Racial and ethnic diversity is discussed in terms of fastest growing groups, where minorities live, the Native American population, and the impact of this diversity on political participation. Immigration is analyzed to reveal sources and destinations, linguistic diversity, effects on schools and the labor market, and socioeconomic effects. The section on American families focuses on trends in marriage and divorce, types of households and families, and household patterns by race/ethnicity. The last topic looks at the distribution of income and poverty as well as at regional and state differences, race/ethnicity differences, the effects of marital status on income, who constitutes the poor, and how income is distributed. In conclusion, it is noted that America's social and economic future depends upon whether current demographic trends will lead to a fragmented and divisive society or to a stronger nation built upon diversity. 相似文献

We prove that the edges of every even graph G=G 1+G 2 that is the join of two regular graphs G 1 and G 2 can be coloured with Δ(G) colours, whenever Δ(G)=Δ(G 1)+|V 2|. The proof of this result together with the results in De Simone and Galluccio (J. Comb. Optim. 18:417–428, 2009) states that every even graph G that is the join of two regular graphs is Class 1. The proof yields an efficient combinatorial algorithm to find a Δ(G)-edge-colouring of this type of graphs. 相似文献

Over the last decades, the European Statistical System has developed many European statistics and indicators to measure social progress and sustainable development. Initially only in a few cases the measuring instruments contained questions on subjective issues. With the adoption of its Communication on “gross domestic product and beyond” the Commission has given an impetus to the development of subjective social indicators. This has led to the establishment of a first set of indicators on quality of life and well-being and to a new instrument (the 2013 EU-SILC ad-hoc module for measuring subjective well-being). This new step in European statistics creates an important potential for researchers to engage in in-depth analysis and for national and European Union policy makers to use the resulting indicators—and in casu subjective well-being indicators—for developing and monitoring policy strategies and programmes. 相似文献

This article analyzes the development of the Egyptian workers' movement in the face of the 25 January Revolution through the notion of dialectical pedagogy. This Gramscian concept is extended by a Vygotskyan analysis of the reciprocal learning processes, which stimulate a proletarian activity system to overcome its economic-corporate predicament. The concrete case study of the Mahalla strike movement (2006–2008) elucidates the transformative-instructive dynamics of autoprolepsis and heterolepsis and the importance of solidarity in developing the worker Subject. The 25 January Revolution expanded the proletarian Zone of Proximal Development and created new possibilities and constraints for the development of the workers' movement. 相似文献
