This paper assesses the ways in which the availability of family planning program outlets influences the likelihood of contraceptive use in rural Thailand. It focuses on a village-level measure of actual availability of sources rather than respondent perceptions of availability. Individuallevel and village-level data collected as part of the second Thailand Contraceptive Prevalence Survey are used to test three hypotheses about the effects of actual availability: that (a) availability of family planning outlets increases the likelihood of contraceptive use; (b) it enhances the effect of a desire for no more children on the likelihood of use; and (c) it weakens the positive relationship between education and the likelihood of use.  相似文献

Since 1949, great social and economic changes have taken place in China. The entire economic structure and social relations are no longer the way they used to be. These changes have also had a strong impact on the size of family households and family structure. Major changes are summarized as follows: (1) The size of the present family household has been greatly reduced from its earlier size. The main reason for this reduction in size is the change of the social system. Under the new social system, the natural population growth rate and family structure have shown the greatest change from the past. (2) The major change in family structure is that small families have replaced the traditional large families. Under the large family system, several generations may stay together as one household, and brothers do not divide the large family even after they are married. Under the small family system, a household is normally limited to the parents and their children. With the gradual disappearance of large families, small families are increasing rapidly. Some households with three generations living together are still in existence, and the young and the old may support each other in their daily life. Both in cities and in rural areas, the traditional custom of respecting one's old parents still exists. There must be a value and necessity for the existence of this particular kind of family structure.  相似文献

An analysis of mortality trends in China, based on data from the 1982 census, is presented. It shows that the mortality rate has gradually declined since 1949, but has recently leveled off and is now on the rise again. The main reasons for this decline were fewer deaths from disease and the changing age structure of the population. It is noted that the mortality rate varies from region to region, with infant mortality in border areas accounting for a large portion of total deaths. An increase in life expectancy has occurred as a result of declining mortality.  相似文献

The impact of heterogeneity in individual frailty on the dynamics of mortality   总被引:31,自引:2,他引:31  
Life table methods are developed for populations whose members differ in their endowment for longevity. Unlike standard methods, which ignore such heterogeneity, these methods use different calculations to construct cohort, period, and individual life tables. The results imply that standard methods overestimate current life expectancy and potential gains in life expectancy from health and safety interventions, while underestimating rates of individual aging, past progress in reducing mortality, and mortality differentials between pairs of populations. Calculations based on Swedish mortality data suggest that these errors may be important, especially in old age.  相似文献

Frequencies and rates of maternal mortality in the United States have declined sharply since the turn of the century. During this decline, researchers have closely examined maternal mortality relative to various risk factors. However, maternal death as currently defined and coded on death certificates may not reveal the true extent of the problem of reproductive mortality. In Georgia, an analysis of death certificates of females ages 10 to 49 indicates that deaths due to pregnancy related conditions are not being discovered by traditional underlying cause-of-death maternal mortality classification. Frequencies and rates were calculated showing the difference between the traditional International Classification of Disease codes for maternal deaths (ICD 630–676) and the reproductive mortality definition used in this paper (which emphasizes the Health Field Concept classification of Lifestyle, Environment, Biology and Health Care Delivery System) (Lalonde, M., 1974 and Laframboise, H. L., 1973). The analysis suggests that a revised definition of maternal mortality be employed to take into consideration all risk factors related to reproductive mortality.  相似文献

Abstract Family history data derived from the records of three parishes in Bavaria provide evidence for several important demographic questions when analysed in conjunction with information concerning the prevalent breast-feeding practices. The results suggest strongly that breast feeding can prolong birth intervals substantially. The evidence concerning the independent influence of infant deaths on subsequent birth intervals is inconclusive. It is clear, however, that even if such an influence did exist it was relatively small, compared to the effect of lactation. In addition the results do not lend support to the hypothesis that couples experiencing low child mortality practised family limitation more than couples experiencing high child mortality. In all three parishes, however, fertility appeared to influence infant mortality. Infants born after short intervals were subject to considerably higher mortality risks than infants following longer intervals.  相似文献

Abstract Of the Caribbean islands, Barbados has the lowest fertility level. The crude birth rate in 1970 was only 20·5 per 1,000, which is one of the lowest found in any country of similar economic development anywhere in the world. In 1960 the crude birth rate was much higher, at about 33·6 and for almost 40 years before that had fluctuated around a value of 33. Thus, a decline of about 40% has been achieved within the comparatively short period of a decade. The reasons for this rapid decline are of particular interest to all those concerned with population growth and economic development in the less developed areas. In Barbados, the importance of population control and the role of family planning was recognised early by the government and other civic agencies, and the Barbados Family Planning Association (BFPA), an autonomous national family planning agency, was established. Since its modest beginning in 1955 the BFPA has grown to be a major social institution, comprising 14 clinics situated in various localities throughout the island. In 1970, a full-time staff of 28 were providing services to an estimated 10,000 clients, about 20% of all women of reproductive age. Funds for the BFPA have come from local government with considerable assistance from international agencies.  相似文献

Biological determinants of differential mortality by sex are examined. The author suggests that a difference in male sex chromosomes is the main reason for the higher mortality rate and lower life expectancy observed in males and for their susceptibility to some genetic diseases. The production of more male fertilized ova is considered as a natural control to balance the sex ratio.  相似文献

The study relates to an investigation of the fertility pattern of a sample of 1018 wives drawn from Lucknow and Kanpur, the two biggest cities of Uttar Pradesh. The sample is stratified with respect to religion and caste, and income. It reveals significant inter-community differences, Muslims and low-caste Hindus showing nearly equal fertility, and high-caste Hindus and Christians showing comparatively lower levels. The proportion of small families (three children or less) is obviously higher in groups with lower fertility, but there is a wide measure of dispersion in each group. Fertility is seen to decline with a rise in income, but not until we cross the income level of Rs 300 per month. Consistent with the differential trends in fertility, striking variations are also observed in the extent of contraceptive practice in different groups. Groups with lower fertility also show a higher frequency of birth control. Birth controllers have lower fertility than the non-controllers, and birth control appears to play a not inconsequential rôle in causing differential trends in fertility.  相似文献

The purpose of this paper is twofold: (a) to provide a complete self-contained exposition of estimating life tables with covariates through the use of hazards models, and (b) to illustrate this technique with a substan-tive analysis of child mortality in Sri Lanka, thereby demonstrating that World Fertility Survey data are a valuable source for the study of child mortality. We show that life tables with covariates can be easily estimated with standard computer packages designed for analysis of contingency tables. The substantive analysis confirms and supplements an earlier study of infant and child mortality in Sri Lanka by Meegama. Those factors found to be strongly associated with mortality are mother’s and father’s education, time period of birth, urban/rural/estate residence, ethnicity, sex, birth order, age of the mother at the birth, and type of toilet facility.  相似文献

The relative earnings growth for immigrants in Norway is computed. Unlike Hayfron (1998, this journal) we define immigrants by country of origin rather than citizenship and perform separate studies of immigrants from inside and outside the OECD region. Replicating Hayfron op.cit. we find that the earnings assimilation is considerably weaker. Further, we find that the earnings of OECD immigrants are comparable to those of natives, while Non-OECD immigrants earn considerably less than natives at the time of entry, but that their relative earnings improve gradually over time. Earnings of different immigrant cohorts converged from 1980 to 1990, indicating a non-linear rate of assimilation. Received: 7 April 2000/Accepted: 4 January 2001  相似文献

For slightly more than a century, psychologists, sociologists, demographers, and others have been studying family structure. The enterprise has been repeatedly characterized as having strong empirical roots, but little theory to nurture it and help it develop. Recently, articles have been published calling for the formalization of family demography, which we define as the discipline devoted to the study of family structure. This paper has the following purposes: (1) To develop a general taxonomy of family structure that unites researchers from several disciplines under one framework; (2) To review important methodological and measurement problems involved in the study of family structure; and (3) To review the recent theory-based empirical literature. We conclude with an assessment of the state-of-the-enterprise.This research was supported in part by a junior faculty research fellowship from the University of Oklahoma to the first author. The Carolina Population Center and the University of North Carolina Department of Psychology provided research and library assistance. Special thanks are extended to Thomas Berndt, George Holden, J. Richard Udry, and several anonymous reviewers who read and commented on earlier drafts of this article.  相似文献

Abstract The aim of the study is to examine the way in which the pattern of mortality in a pre-industrial society differed in catastrophic years from that in 'normal' years. Five Finnish parishes with a total population of 21,000 in 1850 were examined. The deaths were classified by season, age and cause. The results support the theory that epidemics not directly connected with starvation were the main causes of mortality peaks.  相似文献

A number of prior studies have attempted to account for cross-national differences in infant mortality rate using a variety of economic, demographic, and health related variables. These studies have given relatively little attention to the impact of predictors measuring the status of women. The present study, based on a sample of 96 less developed countries circa 1990, tests a series of hypotheses derived from gender stratification theory and industrialism theory. Evidence is presented of an inverse relationship between the status of women and infant mortality rate. The present study shows that it makes a difference whether we use relative or absolute measures of women's status and it shows that in addition to women's educational status, other dimensions of women's status particularly economic status and autonomy are also important predictors of infant mortality rate.  相似文献

Child mortality may affect spacing through biological and behavioral channels. The death of a child may elicit a desire to have another one soon; further, it may interrupt breastfeeding and shorten the sterile period following childbirth. The hypothesis that the child mortality-spacing linkage varies across parities, being strongest in the middle parities, is examined using microdata from Malaysia and the Cox-regression technique. The empirical results lend support to the hypothesis.  相似文献

Summary Previous research on the relationship between extended family residence and fertility has produced conflicting findings. In the present paper, we avoid a major shortcoming of past work by focusing on residence and fertility at a given stage of the life-cycle, i.e. the stage following first marriage. Results show that residence with husband's parents reduces age at marriage. Residence with wife's parents shows no such consistent effect. No evidence was found to support the claim that extended family residence consistently affects the length of the interval between marriage and the first birth. These findings are consistent across four cultural/ethnic groups.  相似文献

Don't Ask, Don't Tell is gaining attention in family studies literature as a cultural specific context to understand lesbian, gay, and bisexual visibility in African-American families and communities. This policy suggests that sexual minorities are accepted within African-American families and communities as long as they do not label themselves or acknowledge publicly that they engage in same-sex relationships. The narratives of two African-American lesbians (aged 26 and 27 years) are chronicled in the present study to reveal their lesbian identity development, lesbian identity management, and how they defined and navigated Don't Ask, Don't Tell. They encountered challenges and successes in a quest to find communities that would embrace and affirm their multiple marginalized identities. Their stories are offered as a point of entry to further inquiry concerning African-American lesbian visibility and identity proclamation within African-American families and communities.  相似文献
