Summary The age patterns of marital fertility levels and decline in modern Asia and historical Europe are analysed in order to answer two questions: (1) How closely do the age patterns of marital fertility in both areas prior to a systematic fertility decline conform to the age pattern of natural fertility? (2) How similar are the age patterns of the fertility transition experienced in Europe in the past, and the age pattern of fertility decline now under way in a number of Asian populations? The answers have important implications for our understanding of the fertility transition. They suggest that modern family limitation (i.e. parity-specific fertility control) was largely absent prior to a secular decline in marital fertility in both Europe and Asia. Furthermore, the evidence indicates that once the practice of family limitation starts to spread among the broader strata of the population, it seems almost inevitably to increase until it becomes a common behavioural norm. In this respect, the modern fertility transition appears to result from the spread of innovative behaviour and cannot be viewed simply as an adjustment to new socio-economic circumstances based on previously established behavioural mechanisms.  相似文献

Natural disasters can lead to significant changes in health, economic, and demographic outcomes. However, the demographic effects of earthquakes have been studied only to a limited degree. This paper examines the effect of the 2001 Gujarat earthquake on reproductive outcomes. This earthquake killed more than 20,000 people; injured 167,000; and caused massive losses to property and civic assets. Using data from two large-scale District-Level Household Surveys (2002–2004 and 2007–2008), we employ difference-in-difference and fixed-effect regression models to compare the outcomes across earthquake-affected districts and their neighboring districts during 5 years before and after the earthquake. We find that the earthquake led to significant rises in childbirth rates. It also reduced birth spacing among uneducated, tribal, and Muslim women, and the incidence of male births among rural women. We find considerable variation in the demographic effects of the earthquake across location, household socioeconomic status, and parental age and education.  相似文献

Using recent data from three national-level surveys conducted in 1995, 2000, and 2004, we provide evidence that Palestinian fertility rates in the West Bank and Gaza Strip, historically among the highest in the world, began to slow especially in the West Bank, but stalled in Gaza during the recent Intifada. The TFR in the early 2000s was 4.6 per woman, down from 6.2 a decade earlier. However, most of the decline in Gaza’s fertility appears to have taken place during the early 1990s, before the onset of the second Intifada. In Gaza, the TFR decreased from 7.4 to 5.7 during the 1990s, but changed only slightly to 5.6 during the second Intifada period. Surprisingly, contraceptive prevalence has not changed during these years, and the transition to lower fertility was mainly due to changes in nuptiality. Demand for children remains high, although there is evidence of unmet need for contraception. The continuing conflict and worsening economic situation provide clues to the persistence of high fertility among Palestinian women.

Recent analyses of Ireland's marital fertility transition based on the Princeton Ig and the Stanford CPA measures are reassessed. Revised county estimates of Ig are subjected to regression analysis, and added insight into CPA is offered by comparing Ireland with Scotland and applying the measure to three specially constructed local data sets.  相似文献

This article presents new estimates of age-specific overall and marital fertility rates for the entire United States for the period 1900-1910. The estimation techniques are the two-census parity increment method and the own-children method. The data sources are the 1900 census public use sample and tabulations of 1910 census fertility data published with the 1940 census. Estimates are made for the total population, whites, native-born whites, foreign-born whites, and blacks. Low age-specific marital fertility at younger ages is consistent with a view of a distinctive American fertility pattern at this time.  相似文献

This paper examines human capital gap between titular ethnicities and Russian-speaking minorities, which has emerged in Estonia, Latvia, and Lithuania during the transition and remains significant after controlling for parental education. For recent cohorts, unexplained gap is declining in Lithuania (despite absence of Russian language tertiary education) and in Estonia. Furthermore, we investigate intergenerational mobility in the Baltic countries. Parental education has a strong positive effect on propensity to obtain tertiary education, both in the Soviet era and post-Soviet period. Transition to the market has weakened mother’s education effect for titular ethnicities, while the opposite is true for minorities.

Few studies provide an insight into what factors contributed to declines in the mortality rates of developing countries before the Second World War. In this paper, statistics on causes of death from Cuba, particularly Havana, are used to investigate what may have been some of the principal determinants of mortality decline in the developing world before the arrival of modern drugs and insecticides. Trends in cause-specific mortality are examined in the light of Cuba's social, economic, medical and public health history. The Cuban experience strongly suggests that in this country public health and sanitary reforms and nutritional improvements were largely responsible for initial declines in mortality throughout the first half of the twentieth century. One important finding is that the impact of these reforms and improved nutrition was greatly influenced by prevailing economic conditions. Periods of economic prosperity facilitated declines in mortality; but in times of adversity, the reverse occurred. It appears that during prosperous periods the maintenance and expansion of public health and sanitary facilities were made possible by increased public and private revenues, and that individuals had access to a more abundant diet. The severe economic crisis of the Great Depression had the opposite effect. With the appearance of sulphonamides in the late 1930s, antibiotics, and residual insecticides and other specific measures at the end of the Second World War, the relevance of economic conditions as a determinant of mortality decline diminished. Although this analysis points to the aforementioned trends, the Cuban experience also suggests that other factors enter into the process of declining mortality and that this phenomenon can only be explained as the result of the complex interplay of many forces.  相似文献

Summary The validity and usefulness of 'desired additional children' and 'ideal family size' as predictors of fertility are analysed in this paper on the basis of longitudinal survey data from Thailand. First, the extent of measurement error in these variables is considered, and it is concluded that the error variance and the true variance are of similar orders of magnitude. Secondly, the changes in attitudes subsequent to births and deaths of children are investigated. It is found that the number of additional children desired is decreased by births and increased by deaths, but less than would be expected if 'desired additional children' represented an unchanging target family size. 'Ideal family size' is almost unaffected by births and deaths. Thirdly, the contribution of attitudinal variables to behavioural models is examined. It is found that desired fertility is explained no better than fertility in a standard economic model. A birth function separating desired children from identifiable physiological factors as explanatory variables indicated that the former was just significant. A model of contraceptive acceptance also found desired fertility to be a significant determinant. Thus, desired fertility can be successfully integrated into behavioural models. But on the whole, its explanatory power was weak, and it was concluded that the independent use of this variable does not significantly improve on models which relate fertility to socio-economic variables directly.  相似文献

The historical pattern of the demographic transition suggests that fertility declines follow mortality declines, followed by a rise in human capital accumulation and economic growth. The HIV/AIDS epidemic threatens to reverse this path. We utilize recent rounds of the demographic and health surveys that link an individual woman’s fertility outcomes to her HIV status based on testing. The data allow us to distinguish the effect of own positive HIV status on fertility (which may be due to lower fecundity and other physiological reasons) from the behavioral response to higher mortality risk, as measured by the local community HIV prevalence. We show that although HIV-infected women have significantly lower fertility, local community HIV prevalence has no significant effect on noninfected women’s fertility.  相似文献

Problem

Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems.

Background

Due to minimal experience and cultural resistance, few practitioners offer vaginal breech birth, and many practice guidelines and training programmes recommend delivery techniques requiring supine maternal position. Fewer practitioners have skills to support physiological breech birth, involving active maternal movement and choice of birthing position, including upright postures such as kneeling, standing, squatting, or on a birth stool. How professionals learn complex skills contrary to those taught in their local practice settings is unclear.

Question

How do professionals develop competence and expertise in physiological breech birth?

Methods

Nine midwives and five obstetricians with experience facilitating upright physiological breech births participated in semi-structured interviews. Data were analysed iteratively using constructivist grounded theory methods to develop an empirical theory of physiological breech skill acquisition.

Results

Among the participants in this research, the deliberate acquisition of competence in physiological breech birth included stages of affinity with physiological birth, critical awareness, intention, identity and responsibility. Expert practitioners operating across local and national boundaries guided less experienced practitioners.

Discussion

The results depict a specialist learning model which could be formalised in sympathetic training programmes, and evaluated. It may also be relevant to developing competence in other specialist/expert roles and innovative practices.

Conclusion

Deliberate development of local communities of practice may support professionals to acquire elusive breech skills in a sustainable way.  相似文献

Abstract. Influences on the fertility of men during the American fertility decline are examined using a sample of about 1700 married men born between 1830 and 1880, all of whom attended Amherst College, Massachusetts. We consider two types of reduced fertility: involuntary childlessness as a function of health in early adulthood, and voluntary fertility control as a function of access to contraceptive technology. The relation between health, as measured by body mass index, and childlessness was nonlinear, with average sized men significantly more likely ever to father children than thin or bulky men. Among men who ever fathered a child, physicians fathered significantly fewer children while having probabilities of childlessness that were statistically indistinguishable from those of other men. Physicians may have had greater access to relatively new contraceptive technologies, which suggests a role for voluntary fertility control.  相似文献

A fundamental question about human behavior is whether fertility responds to disease risk. The standard economic theory of household fertility decision-making generates ambiguous predictions, and the response has large implications for human welfare. We examine the fertility response to the HIV/AIDS pandemic using national household survey data from 14 sub-Saharan African countries. Instrumental variable (IV) estimates using distance to the origin of the pandemic suggest that HIV/AIDS has increased the total fertility rate (TFR) and the number of surviving children. These results rekindle the debate about the fertility response to disease risk, particularly the HIV/AIDS pandemic, and highlight the question of whether the HIV/AIDS pandemic has reduced GDP per capita.  相似文献

A framework developed by Easterlin for the analysis of fertility in developing societies is modified and then tested using a sample of 65 less-developed countries. The focus is on assessing the impact of public policy on the national fertility rate. Public policy is reflected in the average levels of education and health in the population and in the condition of the national family planning program. To test for threshold effects with respect to socioeconomic development, the sample is divided on the basis of the infant mortality rate. Fertility rates in those nations characterized by high infant mortality are likely to be determined more by conditions of natural fertility. Those nations with lower infant mortality, and hence greater socioeconomic development, are more likely to exhibit deliberate fertility control. The results of the regression analysis do suggest that different factors influence the national fertility rate depending upon the stage of development. For the least-developed nations, the secondary school enrollment rate, an indicator of the extent of economic mobility, and the ratio of school age children to teachers, a proxy for the national commitment to human capital formation, are important. For the more advanced of the LDCs, adult literacy and the infant mortality rate seem to predominate. For all the developing nations, however, the results confirm the importance of strong family planning programs. The paper concludes with a discussion of the policy implications of the research.  相似文献

Urbanization and the fertility transition in Ghana   总被引:2,自引:0,他引:2  
This paper examines the way in which migration and urban residence operate to alter fertility outcomes. While urban-rural fertility differentials have long been established for most developing societies, the nature of these differences among migrants and between migrants and those of succeeding generations is not well understood. The evidence presented here suggests that rural-urban migration and urbanization may contribute positively to processes of fertility transition. Using data from the 1998 Kumasi Peri-Urban Survey, which included a 5-year retrospective monthly calendar of childbearing, we suggest that migrants adapt quickly to an urban environment. Our results also reveal generational differences in recent and cumulative fertility. While migrants exhibit higher cumulative fertility than urban residents of the second and third generation, their fertility is significantly lower than rural averages in Ghana. Children of migrants exhibit childbearing patterns quite similar to those in higher-order generations. Most noteworthy is the nature of the disparities in childbearing patterns between migrants and the succeeding generations. Migrant women have higher lifetime fertility than urban natives. Migrant women also exhibit higher fertility over the last 5 years than second generation or high-order urban natives. But these first generation women exhibit lower fertility (vs. urban natives) for the year immediately prior to the survey. These patterns lend support to an interpretation that combines rather than opposes theories of selectivity, disruption, adaptation and socialization. We conclude by discussing mechanisms that might explain these interrelated processes of fertility adjustment and suggest that policies discouraging rural-urban migration need to be revisited.  相似文献
