This paper attempts to examine the differences in sex preference and its impact on fertility behavior among various age groups in the State of Haryana. In India, male children have greater utility over females because of religious, social and economic reasons. Various studies have established the fact that there is a prevalence of sex preference and a marked relationship between son preference and family size. This leads to increased fertility, and ultimately towards population growth rate. Data were collected from the National Family Health Survey report in 1993. The intensity of sex preference on fertility was computed on the basis of contraception method. Moreover, detailed analysis was carried out on the basis of desired additional children and their sex ratio. This study also presents an examination of the Indian system, family planning measures, sex ratio of desired additional children taken as a basis for the measurement of overall effect of sex preference on fertility.  相似文献

中国民间抱养行为由来已久,家庭送养的决策将完全改变儿童的生存和发展的轨迹。囿于送养的隐蔽性和复杂性,且相关研究匮乏,亟需系统性的剖析。文章基于公益平台寻亲数据,运用社会网络、空间分析、数理统计以及地理探测器的方法,探究1981—2010年家庭送养的时空分异特征,并进一步归纳送养决策的流程及原因机制。结果表明:1)送养主体为未满1周岁女童。2)送养人数在时间上呈现“先增后减”的倒“U”型分布,在空间上主要分布在中国东部、中部以及川渝地区。3)家庭送养原因以经济贫困为主,违反生育政策的影响次之。当家庭面临狭小的生育空间时,重男轻女的思想会被强化。4)地理探测器结果揭示,人口因素是影响送养空间分异最主要的原因,自然灾害、计划生育和经济因素在不同时期产生较大影响。5)基于理性选择理论提出了多尺度下的家庭送养的影响机制,认为家庭在作理性送养决策时,往往遵循生存理性、经济理性、制度理性以及社会理性的原则。  相似文献

This study compares the theses of Mamdami, that India's poor have large families as an investment, and Vlassoff, that only a weak connection exists between a child's economic utility and household fertility. Data used in the study were based on a sample of 18 children in Bihar state, India, on 1) expenditures on children, 2) opportunity costs of raising children, 3) child earnings, 4) child earnings given to parents, 5) alternative investments, 6) discount rates appropriate for parents to use, 7) parents' perceptions of the economic value of children, and 8) family size. Costs estimated included food, clothing, schooling, health, other, and opportunity costs in bearing and raising children. Benefits include estimated values for work within and outside the family. 2 balances indicate that 7 or 8 children, aged 6 to 15, provide more labor than they cost to keep. Data suggest that children become valuable to parents at about age 9 or 10. From this age on, benefits increasingly outweigh costs; by the age of 16 or 17, children have repaid their initial costs to parents. Comparing the value of children against local bank interest rates shows that in all cases but one, children provided a better economic investment than savings accounts. The authors suggest that children are an even greater economic investment in poorer households. Doling out condoms and pills is no substitute for child wealth. In Bihar, improving people's economic well-being may be a prerequisite to fertility decline.  相似文献

It is argued that the research agenda on fertility decline needs to be explanatory rather than operational and not tied to government policy justification. The research agenda should be set in the broader developmental and geographic contexts and with consideration of cultural practices. Demographic and Health Surveys provide limited biosocial data, which does not provide a fuller analysis of the factors affecting contraceptive use and effectiveness. Clear associations are drawn between rising contraceptive use and fertility decline and are used as supports for national and international policy makers. Although policy formation may be justified by this research agenda, the view is taken that this is "bad science." Kenya has been used as a model for population change in Africa. Kenya is viewed as a country with obvious direct government involvement in policies on fertility reduction, which mirror the ideological biases of the global model. The global model assumes a universal relationship between fertility and contraceptive prevalence and attaches little significance to cultural differences. However, research recognizes that in Africa family relationships, land tenure, and economic organization are different and highly variable. If economic and social variables on Kenya were available, it is possible that the economic change hypothesis could be proven. Kenya has great regional differences and wide gaps in levels of development. For many countries population growth is the key factor in development, and policies reflect the threat of loan conditions or reductions in foreign aid. Many African countries moved in the direction of reducing population growth through improved health and education, more jobs, improved status of women, and other indirect measures. This approach relies on the Western model of demographic transition. This author argues that knowledge and conclusions about fertility in Africa are more conditioned by ideology rather than technical concerns. In the case of Kenya ideology is supported by research, but a fuller explanation of family formation is not yet available. Kenya's population policy is based on the contraception hypothesis, and data are not yet available for testing other alternative child mortality or economic change hypotheses and constructively informing policy makers about fertility decline.  相似文献

The paper examines the acceptance of birth control practices in India, and examines the relationhsip of these patterns to levels of economic development. A study of selected couples with markedly low incomes revealed that fertility tended to increase until a certain level of per capita income was reached. From this level onward, fertility and desired family size goals declined with increasing economic status. The study reveals an association in India between those less developed states and poor acceptance of family planning. The level of medical and administrative personnel for family planning services is superior in the more developed states and, logically, adoption of family planning practices is also higher. In higher-income states, characterized by relatively higher spatial mobility and literacy rates, the spread of family planning practices is relatively rapid. In less developed states, characterized by poorly developed centralized systems of communication and distribution, a lower spatial mobility of people, and a lower diffusion of knowledge through personal contact, family planning methods tend to spread very slowly or become less and less popular. A classification of Indian states as related to their acceptance of formal family planning policy and governmental efforts has been helpful in developing regionally-oriented program strategies for the future. Such strategies would take into account varying socioeconomic, cultural and administrative infrastructure differences in order to better assure delivery of services. As India also faces a shortage of trained physicians and personnel for the National Family Planning program, a regionally-based spatial allocation policy must be formulated that will divert some family planning personnel from states with high-acceptance patterns to the more densely populated, less developed regions of the country.  相似文献

The reduction of the rate of growth of the Brazilian population from 3% in the 1960s to 2% by 1993 resulted from a significant reduction of fertility. According to the 1986 national maternal-child health and family planning survey (PNSMIPF) results, 43.3% of women were using some type of contraception: 65.6% of married or cohabiting women. Women relied most on sterilization (17.2%), followed by oral contraceptives (OCs) (17%), the rhythm method (2.8%), the condom (1.1%), and others (5.2%). Only in the south was OC use more prevalent (28.5%) than sterilization (12.2%). The proportion of sterilization reached 27.8% in the north/center-east urban regions. In urban areas sterilization averaged 18.7% vs. 12.7% in rural areas. 26.9% of currently married women in the age range of 15-44 years had been sterilized. A 1990 international estimation indicated that the proportion of sterilization amounted to 36.9% in China, 30.95 in India, 29.7% in Brazil, 47.6% in South Korea, 30.4% in Thailand, and 36.5% in the Dominican Republic. The 1986 PNSMIPF survey also indicated that sterilized women were better informed than other women about contraception. 75% of the former had used OCs, 5% had used the diaphragm, 3% the IUD, 30% the condom, and 35% coitus interruptus at one time or other. The sterilized women had an average of 1.7 more children than those who were using other methods of contraception. 48.6% of women were sterilized before the age of 30, when they had had an average of 3.6 children. 66.6% of the sterilized women who had given birth before the age of 20 had 4 or more live births as compared to 5.9% of sterilized women aged 30 with the same number of children. 47% of women without any schooling were using some kind of contraception vs. 77% of those who had completed secondary school. A multivariate analysis also showed that the age of the mother, the number of live births, the educational status of the mother, and family income were positively correlated with sterilization.  相似文献

This article identifies some issues of importance in understanding China's policy of population control. This article presents evidence of trends in fertility, population policy, family planning, and socioeconomic change; and then discusses the conflict between fertility preferences and policy that is evident from studies of ideal family size and sex ratios. Some issues that are identified as "uncertain" include the extent of spread of family planning service delivery and its associated insurance schemes, local family planning policies and cadre responsibility systems, the demand for children, the demand for female children, the economic and environmental consequences of population growth, the fairness of reproductive restrictions and their application, and the extent of coercion in the later-longer-fewer policy era. It is argued that an ethical framework for analyzing China's population policy should include answers to questions about the harm to welfare from population growth, the government's right to demand voluntary reproductive sacrifice or to impose demographic or reproductive restrictions and punishment, and the government's right to impose coercion. If it is accepted that population growth in China has adverse consequences and its control would be beneficial to all, then it must be determined what the nature of the relationship should be between the state and the individual. The author refers to Walzer's (1983) position that the legitimacy of Chinese state power depends in part on whether political leaders at all levels are competent and not corrupt. The rights and duties of the government and individuals must be understood not just in terms of political legitimacy but also in terms of social justice. Social justice is dependent upon the degree of horizontal and vertical consultation and accountability, utilitarian consequences, and protected spheres of individual judgement. Utilitarian theories justify the one-child policy, while deontological theories support reproductive freedom as an absolute right.  相似文献

"Debates concerning the origins and development of the late nineteenth- to early twentieth-century declines in marital fertility and infant mortality in England and Wales have been centred largely on the material provided by answers to the ?special' questions in the 1911 census. In their published form these figures have restricted researchers to an examination of large scale geographic and social class differences in the levels and rates of decline of the two phenomena. This paper outlines research conducted on a sample of individual census returns from the 1911 census. From this data it becomes clear that for Victorian and Edwardian England ?where one lived' was rather more important than ?who one was' in determining both family building strategies and the survival of those children born."  相似文献

Using a sample of 885 females (1/2 of all married women of reproductive age), this study examines the role of education as a determinant of fertility among couples in Kullu town of Himachol Pradesh, India. Of the 885 respondents, only 149 were illiterate. The average family size was 2.88. Findings reveal that 1) the average family size was largest for illiterate respondents (3.57) and for illiterate males (3.76); 2) average family size declined consistently after the middle level of education to 1.29 for post graduate respondents and 2.33 for post graduate males; 3) a negative correlation exists between fertility and education of both husband and wife, with the wife's education having a stronger negative correlation with fertility; and 4) couples with an educational level of matriculation and above have a distinctly smaller family size than those less educated.  相似文献

"In France and Great Britain, the last 30 years have seen considerable evolution in the housing stock...and in household structure....This article describes the dynamic interaction of processes influencing the evolution of both households and dwellings. In the two countries, the life course of individuals has become more and more complex. This translates into an ever greater variety of housing needs, not only at different stages in family life, but also in relation to growing job insecurity regardless of family situation. At the same time, policies encouraging home-ownership seem to have reached their limits, because of the new demand for rented accommodation. The answer to sociological and economic evolution cannot be found in a ?single' type of housing and tenure status, but rather in a wide range of dwellings and in the development of a more flexible housing market."  相似文献

生态地理区域界线划分的指标体系   总被引:17,自引:4,他引:17  
生态地理区域界线由一系列反映生态地理区域特征的指标为依据 ,通过其空间差异落实到具体的空间位置上。客观地认识和划定生态地理区域界线是揭示生态环境时空有序性的重要途径 ,是地域系统研究的基础。生态地理区域界线是两个相邻的、彼此不同的生态地理区质上转变的线或带 ,反映同一等级内划分出来的内部相对一致性与外部的差异性。界线代表有一定宽度的带 ,而且可能随着时间而迁移变化 ,等级越低界线越明显 ,等级越高界线越宽。在生态地理区域划分中 ,先选择人力不能大规模改变的几个主要因素 :温度指标 ,主要指标是日平均气温≥ 1 0℃的天数和积温 ,最冷月平均气温 ,最暖月平均气温等 ;水分指标 ,干湿指数 ,目前比较普遍采用的是年干燥度 ,它可以近似地表征某一地方的干湿程度 ;年降水量的资料通常比较可靠 ,但潜在蒸发的计算需要改进和提高。生态地理区域较高级单位的划分依据侧重考虑生物气候的差异 ,先注意水平地带性 ,由于气候台站的有限性 ,所划分出的界线往往用植被界线去修正 ;而垂直地带性则将潜在植被与气候联系起来 ,按照降水量、潜在蒸发率和生物温度来进行划分。如何处理级别与依据和指标之间的关系是另一个重要问题 ,在这个问题的处理上 ,国内外很不统一。  相似文献

There is every indication that Africa's population growth will remain well above the world average for the remainder of this decade and probably for the rest of this century. With the exception of the island states and parts of North Africa, fertility levels show little indication of change. This is in part a reflection of little desire for small families, as well as a consequence of limited or even restricted family planning services. Great diversity in attitudes regarding population policy prevails among African governments, ranging from extreme pronatal to committed antinatal. Even with antinatal policies, however, many African states have yet to attain any significant success in depressing their rates of growth. To date, Mauritius can be cited as the only state to have almost achieved the transition from high to low fertility. The consequence of these continuing trends is that Africa will see further increases in its youth dependency ratio. Pressures on infrastructural services will therefore increase, and the problems of generating employment will intensify. While demographic factors are by no means the only ones creating economic stress on the continent, they clearly are contributory. Unlike Asia or parts of Latin America, Africa's problem is less a matter of too many people but rather 1 of excessive growth in too short a time frame. A realistic and effective long-term population policy, therefore, is an immediate need. Several countries including Nigeria (with a pouplation of over 80 million) are experiencing a crude birth rate of 50 or more/1,000. At least 4 countries, including Kenya, are currently doubling their population in 20 years or less. With these current population trends, a demographic transition to low vital rates must assume passage through an even higher growth phase than is currently being experienced because the fall in birth rates tends to occur much later than the fall in death rates. Government population policies and the status of family planning activities are illustrated according to natal sentiments and attitudes. Trends in national vital rates and of population structures in Africa are illustrated.  相似文献
