As the age at marriage continues to rise in East and Southeast Asia, the fertility behavior of unmarried teenagers is receiving more attention from population policymakers. In addition to fertility reduction through family planning, Asian societies today consider population planning strategies in relation to national needs and social goals, including such matters as the population's growth rate, age structure, educational quality and skills. The number of single youth in Asia is growing much more rapidly than the total youth population. By the year 2010, for example, India is projected to have nearly 70 million single teenagers, aged 15-19, 188% more than in 1980. In many developing countries today, such as the Philippines and Korea, the rising age at marriage has combined with rapid urbanization, improved status for women, and more educational opportunity to alter both the behavioral norms of young people and the traditional means of social control over youth. Studies of contemporary adolescent sexuality have been conducted in 4 Asian countries. In the Philippines an overt independent youth homosexual culture was found to exist in urban and to some extent rural areas. In Thailand research revealed little conservative resistance to family planning or to contraceptives for young unmarried people. Surveys in Taiwan indicate that behavior related to dating and choice of spouse has become more liberal, and a survey in Hong Kong revealed a higher level of premarital sex and use of prostitutes among Chinese men than expected. Population policy perspectives that need to be considered in these changing times include: 1) issues of access to family planning services by unmarried people below the legal age of maturity; 2) the development of social institutions, such as exist in Thailand and the Philippines, to guide adolescents' behavior; 3) more extensive study of adolescent sexuality; 4) establishment of the scope of family policy.  相似文献

The second half of the twentieth century witnessed the development of a crusading spirit and massive technical aid aimed at reducing fertility levels and rates of population growth in developing countries, and also the involvement of demographers in these events. The demographers at Princeton University’s Office of Population Research, Frank Notestein and his colleagues, have been singled out by recent authors as playing a unique role in bringing about these changes, and they have been criticized for encouraging demographers to become involved, so eroding their scientific objectivity. This paper examines the development of relevant population thought and theory in the English-language literature over the first half of the twentieth century. It concludes that in the circumstances of the second half of the twentieth century, it was inevitable that developed countries and their demographers would become involved in controlling fertility levels in developing countries. The OPR story should be seen largely in terms of how the world’s leading demographic center and its demographic transition theory were swept along by global changes. As those developments started, attitudes to population change in densely settled Asia became Malthusian, even as population growth accompanied by mortality decline in Asia demonstrated that, at least in the short term, the positive checks were disappearing.  相似文献

Issued to mark the Population Reference Bureau's 50th anniversary, this issue updates the story of world population presented in its popular predecessor of 1971, "Man's Population Predicament." Estimated at 1/2 billion in 1650, world population reached about 2 billion in 1930, 4 billion in 1975, and is projected to be about 6 billion in 2000. Most of today's rapid growth is occurring among the 3/4 of the world's peoples living in less developed countries where the post-World War II gap between high birth rates and falling death rates has only recently begun to narrow. This growth, coupled with high consumption in developing countries, is putting tremendous pressures on the Earth's resources, environment, and social fabric. New evidence on Europe's population transition and from China, Indonesia, and Thailand in the 1970s suggests that well-designed family planning programs can speed fertility decline but rapid worldwide attainment of replacement level fertility will also require special development efforts and measures that go beyond family planning. Current projections of the world's ultimate peak population range from 8 billion in the mid 21st century to 11 billion in about 2125, depending on when replacement-level fertility is reached. China's drive for a drastic birth rate reduction and the oil crisis might change fertility behavior more rapidly than most demographers have heretofore thought likely.  相似文献

Population Council demographer John Bongaarts and his colleague Griffith Feeney argue that recent concern about a lack of births overlooks the fact that many women in developed countries are simply choosing to bear children later than women used to. So-called birth dearths are often caused by temporary delays in childbearing. The two demographers have designed a new way for demographers to account for the timing, or tempo, of childbearing in estimates of fertility. Their tempo-adjusted total fertility rate (TFR) allows demographers to correct skewed fertility trends, such as those leading to projections of birth dearths. The new measure provides a better indication of women's true propensity to bear children. Standard measures of fertility are distorted by changes in tempo. Such changes occur when large numbers of couples delay or accelerate their initiation of family building. The authors used historical data and theoretical arguments to validate the tempo-adjusted TFR, which improves upon the two common measures of fertility. Flaws in the TFR and the completed fertility rate (CFR) are corrected by Bongaarts and Feeney's new measure. To demonstrate their new tool, they examined the below-replacement fertility seen in recent decades in the US. By the mid-1990s, the TFR in almost every developed country had fallen below the replacement level of 2.1 births/woman, and in Italy, Spain, and Germany it fell below 1.5. If such fertility persists, declining population size, extreme population aging, and financial pressure upon social security systems may result. However, if fertility preferences hold at current levels, the very low fertility rates observed in the developed world will approach 2 children/couple.  相似文献

人口转变的概念从提出到现在已有80多年的历史。数十年来,许多学者对人口转变的研究和贡献,使之成为人口学最有影响的理论之一。它概括了人类在从传统社会向现代社会转变的过程中人口再生产的演变特点以及这种演变的原因和社会经济后果。到了上个世纪80年代后期,欧洲学者范德卡及其同事提出了"第二次人口转变"的概念,以此概括二战以后发生在西欧的一系列人口和婚姻家庭的变化以及生育率现象。20世纪90年代后,又有学者用"第三次人口转变"表述欧美国家持续的低生育率和高迁入率导致的人种结构的变化。文章认为,"第二次人口转变"和"第三次人口转变"的提出者们的研究是非常有启发性和有价值的,但并不赞成他们将自己的研究内容冠以"人口转变"。  相似文献

Abstract To measure changes in fertility brought about by specific family planning programmes has been one of the problems faced by demographers as well as policy-makers. This problem is particularly difficult in developing countries where the basic data are poor. Hence, there is a need to find indices of fertility that are easy to obtain, sensitive to changes in fertility and either not grossly affected by errors in data, or alternatively amenable to correction of data errors. Among many possible indices, the open live birth interval has attracted attention of many researchers and experts.(1).  相似文献

Aspects of below-replacement fertility have long been debated among professional demographers. This paper describes the corresponding popular debate about low fertility by analyzing 437 newspaper and magazine articles from eleven developed countries during 1998 and 1999. Despite the diversity in the national debates due to different socioeconomic, political and demographic backgrounds, our study finds important commonalties in the way low fertility is debated: First, countries emphasize consequences and potential interventions rather than causes in their popular debates over low fertility. Second, our study reveals that the popular press discusses low fertility as a serious concern with mostly negative implications, despite the fact that many of the causes of low fertility are associated with social and economic progress. Third, the variety of issues and perspectives revealed in the popular debate, while cohesive in general ways, invites a role for demographers in informing an accurate public discussion of low fertility, which will help form the most appropriate policy outcomes.  相似文献

One of the major goals of family planning programs worldwide has been to reduce the level of fertility in hopes of slowing the rate of natural increase and promoting social and economic development. Such programs have now been in existence for sufficient lengths of time to have had an impact on fertility levels. In general countries with organized family planning programs, marked declines in fertility levels have been observed. The extent to which such declines may be credited to organized programs has not been rigorously measured because an appropriate research methodology has been lacking. This paper describes one method of directly linking declines in fertility levels to the contraceptive protection experienced by a population. The contribution of organized family planning programs is estimated by decomposing the amount of total contraceptive protection into within-program and outside-program sources.  相似文献

In proposing measures that might improve adverse projected population futures, many demographers have endorsed feminist demands for family-friendly social policies and gender equity in the home. This paper provides a constructive critique of some versions of this argument. Without presenting new empirical data, it makes a case for the use of alternative conceptual tools in study design. It does so by focusing on three underpinnings of claims that fertility is lowest in countries with the greatest disparity between public and private patriarchy. Using Italy and Italians as an example, the paper discusses empirical measurements of the domestic division of labour, depictions of Italian family traditions and theorizations of family dynamics more generally, and wider understandings of modernity and tradition, both on the canvas of grand theory and within ethnographies of Italian families. The paper concludes with examples of studies that use the suggested conceptual framework.  相似文献

人口增长的长期过程一直是充满困惑与引发争论的话题,将人类复归到生态系统的普通成员,按照生态学逻辑构建一个由替代生育率内生引导、人口容量外生制约的人口增长新模型,以代替用具体社会经济因子解释短周期人口变动的传统思路,探讨生育率转变的一般模式及人口发展的长期趋势。工业革命以来,全球人口已经或正在经历着第一次、第二次生育率转变,全球生育率演变可以聚类为欧美、亚非拉、撒哈拉以南非洲和东亚四种区域模式;在计划生育政策的推动下,我国在短短的三十年内完整经历了两次生育率转变。极限替代生育率是生育率演变的长期目标,但当前已有一些国家跌破更替水平,这也许会成为各个国家的普遍经历,预示着人口容量约束的日益显性化;世界及主要国家的人口规模正在日益逼近其容量极限,并会在惯性驱动下突破容量限制,达到峰值后再以负增长方式趋近人口容量,同期的生育率也将向极限替代生育率递增复归。按趋势模拟世界和中国的可持续人口容量分别约为65亿人和12亿人。研究设计出测量人口增长惯性的新指标——人口增长惯性系数,它是生育率与实时替代生育率之比或出生率与死亡率之比,相比常用的人口惯性因子更为简便易行。  相似文献

This pape revaluates a family planning pilot project conducted by the Pakistan Academy for Rural Development in Comilla, East Pakistan. The evaluation is based upon an analysis of the extent to which adoption of conventional contraceptives (condoms and foam tablets) has reduced fertility in selected villages of the Comilla-Kotwali precinct, during the years 1962-66.The study was carried out by comparing adopter and non-adopter rates of pregnancy and analyzing the trends in pregnancy reduction that resulted from adoption. The findings indicate that (1) although the pregnancy rate of adopters has increased steadily throughout the time period, in 1966 the rate is still less than half of what was expected had adoption not occurred; (2) contraceptive use-effectiveness decreases with length of time of use; and (3) pregnancy reduction has been declining since 1964.  相似文献

Abstract The study of nuptiality has taken on urgency, for demographers as well as for sociologists, with the increased world concern over sustained high fertility and the evident contribution of early marriage to that high fertility. Moreover, along with despair over the efficacy of conventional family planning programmes has come an expectation that more basic institutional changes, such as changes in marriage patterns, will be necessary in order finally to achieve a tolerably low world population growth rate. Yet our understanding of the determinants of such primary nuptiality dimensions as age at first marriage is very imperfect and unlikely to give much guidance in policy formation.  相似文献

In April 1985 the State Statistical Bureau of China conducted a fertility sampling survey in the provinces of Hebei and Shaanxi, and Shanghai municipality covering a population of 93,000,000. The target group was married women under 50 whose knowledge and use of contraceptives are the main content of this survey. The IUD has been used by 62% in Hebei, 61% in Shaanxi, and 55% in Shanghai, and is most popular with women over 30 who have had at least 1 child. Married women who have used the pill make up 33% in Shanghai, 14% in Hebei, and 7% in Shaanxi. Female and male sterilization are used by women who have had more than 2 children (15.7% in Shanghai, 40% in Hebei, and 28% in Shannxi). 70-80% have used contraception of some type, reflecting the success of the family planning program.  相似文献

During the past quarter century fertility has dropped below replacement levels in many parts of the world. According to United Nations estimates, in 2005 this was the case in 65 countries, comprising 43 percent of the world's population. In many cases, most notably in Europe and East Asia, the shortfall of fertility from the level that would be necessary in the long run to sustain a stationary population is substantial. In Europe, for example, the average total fertility rate for the period 2000–2005 was 1.4. Indefinite maintenance of such a level implies a shrinkage of the total population by one‐third over a generation–roughly every 30 years. Accompanying that rapid decline of total numbers would be an age structure containing a preponderance of the elderly, posing extreme adjustment difficulties for the economic and social system. Societies that wish to avoid radical depopulation would have to engineer a substantial rise infertility–if not to full replacement level (slightly more than two children per woman), then at least to a level that would moderate the tempo of population decline and make population aging easier to cope with. An additional counter to declining numbers, if not significantly to population aging, could come from net immigration. This is the demographic future assumed in the UN medium‐variant projections for countries and regions currently of very low fertility. Thus, for example, in Europe over the period up to 2050 fertility is assumed to rise to 1.85 and net immigration to amount to some 32 million persons. The UN projections also anticipate further improvement in average life expectancy–from its current level of 74 years to 81 years. This factor slows the decline in population size but accelerates population aging. Under these assumptions, Europe's population would decline from its present 728 million to 653 million by 2050. At that time the proportion of the population over age 65 would be 27.6 percent, nearly double its present share. Demographic change of this nature is not a novel prospect. It was envisioned in a number of European countries and in North America, Australia, and New Zealand in the late 1920s and early 1930s. Concern with the possible economic and social consequences generated much discussion at that time among demographers and social scientists at large and also attracted public attention. Possible policy measures that might reverse the downward trend of fertility were also debated, although resulting in only hesitant and largely inconsequential action. The article by D. V. Glass reproduced below is an especially lucid and concise treatment of demographic changes under conditions of low fertility and their economic and social implications. It appeared in Eugenics Review (vol. 29, no. 1, pp. 39–47) in 1937 when the author was 26 years old. Glass's line of argument is broadly representative of the main focus of demographic analysis in the mid‐1930s on aspects of population dynamics, applying the then still novel analytical tool of the stable population model. It also echoes the work of economists then witnessing the great difficulties capitalist economies faced in adjusting to structural changes in consumer demand and labor supply. While Glass addresses these issues primarily with reference to England and Wales, he sees the issues as affecting all industrialized countries. The Malthusian problem of relentless population growth he persuasively declares to be irrelevant for these countries. The Western world faces the opposite problem: population decline, a trend only temporarily masked by the effects of an age distribution that still has a relatively high proportion of women in the child‐bearing ages, reflecting the higher fertility level of the past. A stationary population, Glass cogently argues, is to be welcomed, and he considers the absolute size at which zero growth would be achieved relatively unimportant. In contrast, a continuous population decline would have “thoroughly disastrous” results in an individualist civilization and in “an unplanned economic system.” And, he concedes, somewhat quaintly, that sustained below‐replacement fertility would pose a great problem “even in a country in which the means of production were owned communally.” Glass's conclusions about the reversibility of low fertility are as pessimistic as those of most informed observers today. Still, he sees hope in a future “rationally planned civilization” that would “produce an environment in which high fertility and a high standard of life will both be possible.” In this context, high fertility means the level necessary to sustain the population in a stationary state. By present‐day standards the level Glass calculates as needed for long‐term zero growth is indeed fairly high: 2.87 children per woman. But that figure reflects the fact that, when he wrote, mortality up to age 50 was still fairly high and fertility occurred almost wholly within marriage; it also assumes zero net immigration. In the last 70 years much has changed in each of these three components of population dynamics, both in England and Wales and in the rest of Europe. Still, Glass's commentary remains highly relevant to the discussion of the problems of low fertility today. David Victor Glass (1911–78) was associated with the London School of Economics throughout much of his scientific career. He followed R. R. Kuczynski as reader in demography in 1945 and became professor of sociology in 1948. His work on demography, population history, and population policy had already made him one of the most influential demographers in pre‐World War II Britain. After the war he rose to international prominence through pioneering work on the Royal Commission of Population; through his research on historical demography, the history of demographic thought, and social mobility; and through founding, in 1947, the journal Population Studies, which he edited until his death.  相似文献

In 1983, the ESCAP region added 44 million people, bringing its total population to 2600 million, which is 56% of the world population. The annual rate of population growth was 1.7% in 1983 compared to 2.4% in 1970-75. The urban population rose from 23.4% in 1970 to 26.4% in 1983, indicative of the drift from rural areas to large cities. In 1980, 12 of the world's 25 largest cities were in the ESCAP region, and there is concern about the deterioration of living conditions in these metropoles. In general, however, increasing urbanization in the developing countries of the ESCAP region has not been directly linked to increasing industrialization, possibly because of the success of rural development programs. With the exception of a few low fertility countries, a large proportion of the region's population is concentrated in the younger age groups; 50% of the population was under 22 years of age in 1983 and over 1/3 was under 15 years. In 1983, there were 69 dependents for every 100 persons of working age, although declines in the dependency ratio are projected. The region's labor force grew from 1100 million in 1970 to 1600 million in 1983; this growth has exceeded the capacity of country economies to generate adequate employment. The region is characterized by large variations in life expectancy at birth, largely reflecting differences in infant mortality rates. Whereas there are less than 10 infant deaths/1000 live births in Japan, the corresponding rates in Afghanistan and India are 203 and 121, respectively. Maternal-child health care programs are expected to reduce infant mortality in the years ahead. Finally, fertility declines have been noted in almost every country in the ESCAP region and have been most dramatic in East Asia, where 1983's total fertility rate was 40% lower than that in 1970-75. Key factors behind this decline include more aggressive government policies aimed at limiting population growth, developments in the fields of education and primary health care, and greater availability of contraception through family planning programs.  相似文献

Since 1960 a debate has taken place between demographers and natural scientists over projections of world population into the future and the methods appropriate for making projections. Underlying this debate is a disagreement over the factors which influence human population growth. To the usual factors of fertility and mortality the natural scientists emphasize the human population's ability to communicate and thereby to enlarge available resources. Also at issue are different philosophies concerning the manipulation of data. The debate between demographers and natural scientists bears many of the features of a scientific revolution as described by Thomas Kuhn. The new theory also meets the criterion of scientific growth contained in the correspondence principle. The theories used by demographers and natural scientists have political implications, since the demographers assume stability whereas the natural scientists observe instability.  相似文献

An overview is provided of Middle Eastern countries on the following topics; population change, epidemiological transition theory and 4 patterns of transition in the middle East, transition in causes of death, infant mortality declines, war mortality, fertility, family planning, age and sex composition, ethnicity, educational status, urbanization, labor force, international labor migration, refugees, Jewish immigration, families, marriage patterns, and future growth. The Middle East is geographically defined as Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, Yemen, Gaza and the West Bank, Iran, Turkey, and Israel. The Middle East's population grew very little until 1990 when the population was 43 million. Population was about doubled in the mid-1950s at 80 million. Rapid growth occurred after 1950 with declines in mortality due to widespread disease control and sanitation efforts. Countries are grouped in the following ways: persistent high fertility and declining mortality with low to medium socioeconomic conditions (Jordan, Oman, Syria, Yemen, and the West Bank and Gaza), declining fertility and mortality in intermediate socioeconomic development (Egypt, Lebanon, Turkey, and Iran), high fertility and declining mortality in high socioeconomic conditions (Bahrain, Iraq, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates), and low fertility and mortality in average socioeconomic conditions (Israel). As birth and death rates decline, there is an accompanying shift from communicable diseases to degenerative diseases and increases in life expectancy; this pattern is reflected in the available data from Egypt, Kuwait, and Israel. High infant and child mortality tends to remain a problem throughout the Middle East, with the exception of Israel and the Gulf States. War casualties are undetermined, yet have not impeded the fastest growing population growth rate in the world. The average fertility is 5 births/woman by the age of 45. Muslim countries tend to have larger families. Contraceptive use is low in the region, with the exception of Turkey and Egypt and among urban and educated populations. More than 40% of the population is under 15 years of age. The region is about 50% Arabic (140 million). Educational status has increased, particularly for men; the lowest literacy rates for women are in Yemen and Egypt. The largest countries are Iran, Turkey, and Egypt.  相似文献

In the past, one of the concomitants of development has been a sustained reduction in fertility. As a result of this experience, demographers hypothesize that in a society in which fertility is lower in urban areas, among the upper socioeconomic status groups and the better-educated, fertility will decline to a moderate level as the country changes from a rural, agricultural socioeconomic structure, with low levels of living and education, to an urban, industrial structure, with rising levels of living and education.The data analyzed in this study indicate, however, that though substantial social and economic development (as measured by changes in industrial structure, per capita income, urbanization, and education) occurred in Brazil from at least 1920-40 to 1960, during which time fertility differentials of the kind indicated above existed, fertility has shown little or no tendency to decline. Between 1940 and 1960, in fact, the birth rate appears to have remained fairly constant around 43. With the death rate steadily dropping, the rate of natural increase and population growth (given a small net in-migration) has been accelerating. p ]From a theoretical point of view, these facts reinforce a growing realization, based on similar findings in some other developing countries, that the prevailing theoretical ideas concerning the relationship between development and fertility require modification, particularly in the direction of greater specificity. On the practical side, the question is raised whether Brazil's rate of economic development during the postwar period up to 1960 can be maintained, let alone increased, in the face of a population growth rate which will probably average 3.2-3.5 percent for the period 1960-70 and which, in the absence of a decline in fertility, is likely to accelerate further.  相似文献

In the past 50 years global population grew by 3.7 billion. There is a large unmet need for family planning and wherever women have been given the means and the information to decide if or when to have the next child, then family size has fallen, often rapidly. However, since the UN 1994 Cairo conference on population and development, support for international family has collapsed and fertility declines in many of the poorest countries have stalled. Amongst some of the most vulnerable groups family size has risen. The investment made in voluntary family planning will largely determine whether, in the next 50 years, the global population grows to something less than 8 billion or to over 10. The trajectory taking us to the higher figure could jeopardize any possibility of transitioning the global economy to a biological sustainability. Much precious time has been lost. Almost all the additional growth in population will take place in the world’s poorest countries, and it is imperative that the international community act to improve access to family planning in those countries, within a human rights frame framework.  相似文献

Fertility decline in central and eastern Europe (CEE) since the fall of the communist regimes has been driven by both stopping and postponement of childbearing: two processes that have been related to crisis and economic development, respectively. In the Western Balkans these economic and political contexts followed each other in the form of a biphasic transition. I examine whether this sequence triggered fertility responses like those observed elsewhere. Relying on three independent data sources, I cross-validate the levels of, and describe the trends in, union formation and fertility (by birth order) between 1980 and 2010. Results do not reveal widespread declines in fertility to lowest-low levels during the most acute period of crisis. The subsequent postponement of marriage and first birth was also limited, and the two-child family remains the norm. This relative resilience of childbearing patterns compared with other CEE countries is discussed with reference to the institutional context.  相似文献
