Demographic and socioeconomic characteristics of Korean Americans in the United States in 1980

"Based on the analysis of 1980 [U.S. Census] Public-Use Microdata Samples, this article demonstrates that the Korean immigrant stream, particularly men, has been very selective even before the 1965 reform.... Despite the educational superiority and somewhat positive occupational position, Korean men in the U.S. are seriously disadvantaged in income regardless of nativity status. Korean Americans are not as successful as whites in translating their education into occupation and income; they are better educated for the same job, but experience a lower income return to the same education and the same occupation."     

Demographic change,rising earnings inequality,and the distribution of personal well-being, 1959–1989

This paper uses new methods to determine the sources of the sharp fall and then the steep rise in personal income inequality between 1959 and 1989. The increase in the proportion of single-head families tended to boost inequality over the entire period. Forty percent of the reduction in income inequality in the 1960s occurred because of the decline in earnings inequality among male heads of families; more than one-third of the increase in inequality after 1969 occurred because inequality in male earnings soared. Since 1979 females’ gains in earnings have increased inequality because these gains have been concentrated increasingly in families with high incomes     

High-risk families: the unequal distribution of infant mortality in nineteenth-century Sweden

An analysis of infant mortality (based on 133,448 births) in two regions, Sundsvall and Skellefte?, in north-eastern Sweden during the nineteenth century shows that infant mortality was highly clustered with a relatively small number of families accounting for a large proportion of all infant deaths. Using logistic regression, two important factors were found to be associated with high-risk families: (i) a biological component evidenced by an over-representation of women who had experienced stillbirths, and (ii) a social component indicated by an increased risk among women who had remarried. The results strengthen the argument for using the family rather than the single child as the unit of analysis. The clustering of infant deaths points to the need to re-evaluate our interpretations of the causes of infant mortality in the past.     

Demographic transitions: analyzing the effects of mortality on fertility

The effect of mortality reductions on fertility is one of the main mechanisms stressed by the recent growth literature in order to explain demographic transitions. We analyze the empirical relevance of this mechanism based on the experience of developed and developing countries since 1960. We distinguish between the effects on gross and net fertility, take into account the dynamic nature of the relationship, and control for alternative explanatory factors and for endogeneity. Our results show that mortality plays a large role in fertility reductions, that the change in fertility behavior comes with a lag of about 10 years and that both net and gross fertility are affected. We find comparatively little support for explanations of the demographic transition based on changes in GDP per capita.     

Demographic responses and socioeconomic structure: Population processes in England and Wales in the nineteenth century

This paper explores some theoretical and empirical aspects related to the theory of change and multiple response. The empirical analysis focuses on 600 relatively small and homogeneous geographical units of England and Wales for the period 1851-1910. These units are classified into six identifiable socioeconomic types and the analysis is male for each of them. Two interrelated tissues are studied. First, a set of explanatory variables, connected either with strain or with factors relieving strain, is constructed. The effects of these explanatory variables on nuptiality, marital fertility, and migration responses are examined for each socioeconomic type, with respect to their significance, intensity, and direction. The patterns of these effects show general consistency with multiphasic response considerations for all socioeconomic types. A significant finding in this part is that migration affects very strongly the intensity of the marital fertility decline response. The second issue deals with theoretically expected patterns of interrelationships among responses in terms of substitutability and complementarity. The theoretical interrelationships are compared with the empirical for each socioeconomic type; and in general, consistency is established. Moreover, these interrelationships can be interpreted for each socioeconomic type in a way that appears to be consistent with multiphasic response considerations. An important finding in this part is that emigration and marital fertility decline are substitute responses in agricultural-based districts. Implications of the findings are discussed.     

Responsive Survey Design,Demographic Data Collection,and Models of Demographic Behavior

To address declining response rates and rising data-collection costs, survey methodologists have devised new techniques for using process data (“paradata”) to address nonresponse by altering the survey design dynamically during data collection. We investigate the substantive consequences of responsive survey design—tools that use paradata to improve the representative qualities of surveys and control costs. By improving representation of reluctant respondents, responsive design can change our understanding of the topic being studied. Using the National Survey of Family Growth Cycle 6, we illustrate how responsive survey design can shape both demographic estimates and models of demographic behaviors based on survey data. By juxtaposing measures from regular and responsive data collection phases, we document how special efforts to interview reluctant respondents may affect demographic estimates. Results demonstrate the potential of responsive survey design to change the quality of demographic research based on survey data.     

Sibling models of socioeconomic effects on the timing of first premarital birth

Data on 1,090 pairs ofsisters from the National Longitudinal Survey of Youth are used to estimate the effects of observed individual-level factors, common family-level variables, and shared unobserved family-level traits on the timing of premarital births. Results show a moderate correlated risk of premarital childbearing among siblings after controlling for the effects of measured covariates. The effect of older sisters’ out-of-wedlock childbearing on the timing of younger sisters’ premarital birth is overestimated when shared unmeasured family-level traits are ignored. Public policy measures designed to reduce premarital births have a smaller multiplier effect via reduced younger sisters’ premarital births because unmeasured family-level factors are less amenable to policy measures. However, because the older-sibling effect is large when other sources of variability in premarital birth timing are controlled, interventions may be effective in reducing premarital births among young women in high-risk families.     

An empirical study of the effects of socioeconomic development on fertility rates

Recent studies by Adelman and by Friedlander and Silver, which have investigated whether regression equations derived from cross-section data can be used to predict the impact of socioeconomic development on changing levels of fertility, are reviewed critically. Regression analyses based on data for 57 countries c. 1960 show that fertility (gross reproduction rate) varies cross-sectionally with region as well as with level of development (as measured by per capita income, percent labor force in primary sector, expectation of life, illiteracy rate). Using equations derived from the cross-section study and time-series data for five European countries during the period that their fertility rates fell, it is shown that predictions about past fertility changes are in error. The results suggest caution in the use of cross-section relations to predict the course of fertility in developing countries.     

Law, marriage and illegitimacy in nineteenth-century Germany

Abstract Concern arose among legislators in several German States during the first half of the nineteenth century about overpopulation and increasing numbers of the impoverished classes. This led them to pass legislation restricting marriage to those considered by the community authorities as morally and financially capable of rearing a family. Census data at the time of the repeal of these laws indicate the extent to which they succeeded in repressing marriage. Declining illegitimacy which paralleled the repeal, however, suggests strongly that the legislation was far less effectual in limiting reproduction than it was in preventing marriage. Added confirmation of this interpretation is provided by the contrasting nuptiality and illegitimacy patterns of German states with liberal marriage regulations.     

从一次人口转变到二次人口转变——现代人口转变及其启示

在扼要解析狭义人口转变及其经典模型的基础上,认为第二次人口转变的提出,是结合人口"中间变量"从广义上阐释了人口变化的内在动因与作用机理,进而在宏观、中观和微观三个层面引入了对现代人口转变与社会变迁关系的思考。主张人口转变是一个多维的动态历史过程,蕴涵着婚姻、生育、家庭、健康、人口调控等系列转变。提出第二次人口转变在中国的城市地区已露端倪。最后特别指出人口转变不仅仅是人口变化,更重要的是将其嵌套的社会变迁,两者关系的空前紧密折射着社会变化与社会需求。过去30年中国通过计划生育让人口"适应"了经济腾飞,而今后三、五十年以至更长时间,应使人口的"主体"地位逐步复归,让经济社会发展适应新的人口变化与社会需求,提高人口生存与生命质量,这才是发展的目的本身。     

中国人口转变、人口红利与经济增长的实证

我国人口年龄结构的变动使得劳动负担逐渐下降,这对于储蓄水平的上升和劳动力投入效率的提高具有显著的促进作用;我国劳动负担比与经济增长呈现出明显的负相关,劳动负担比每下降1个百分点,经济增长将提高1.06个百分点,在过去的30年里劳动负担降低累计带来的经济增长占总增长的27.23%。通过计量检验证明人口年龄结构变动所产生的促进经济增长的人口红利是存在的。由此我们推断,由于未来的人口年龄结构变动趋向人口老龄化,劳动负担逐步上升,这将会对未来的经济增长造成制约。利用未来10～20年时间较轻的劳动负担的机遇期,我们应当建立良好的教育、人力资本投资、社会保障等方面的制度以及制定积极的人口政策,调整当前生育政策、适时执行宏观经济政策(劳动就业政策)来应对已发生的、正在进行的人口变动,使我国的经济继续保持强有力的增长态势。

Life course events and residential change: unpacking age effects on the probability of moving

We know that life course events, especially divorce and separation, trigger residential moves, but we know less about how these and other life course events intersect with how far people move and the relationship with labour market change. This research uses data from the Household, Income and Labour Dynamics Survey in Australia to model a set of life course events and their intersection with the distance of move. I examine essentially positive events, marriage and new births and not so positive events, separation and divorce, and the unexpected events of widowhood and job loss, and their outcomes in the housing market. For the decision to move, the models partly parallel other studies of life course events and their role in the mobility decision, but the results provide enriched results about how age and life course events intersect. The analysis shows in greater detail how age acts as a proxy for complicated life course intersections with moving. The disruption of divorce and separation, as expected, increases the probability of moving but with different effects over distance. Households move in response to these life events but they are much less likely to change metropolitan locations, which reflects the embedded nature of family change and location. Overall, the research enriches previous studies of age-related links to migration and mobility.     

Demographic Cycles,Cohort Size,and Earnings

This article examines whether position in the demographic cycle is an important factor in determining earnings and earnings growth. Earnings equations for white males are estimated by using March Current Population Survey data. Position in the demographic cycle is captured by including both measures of own cohort size and the size of surrounding cohorts in the estimated earnings equations. Position in the demographic cycle matters. Increases in own cohort size lead to flatter earnings profiles, whereas increases in the size of surrounding cohorts are associated with steeper earnings profiles. The net effect is that those who enter the labor market before or after the peak of the demographic cycle start out with lower earnings but experience faster earnings growth. This pattern is uniform across all schooling groups: high school dropouts, high school graduates, those with some college, and college graduates.     

Low socioeconomic status increases effects of negative life events on antenatal anxiety and depression

Problem

Low socioeconomic status and prior negative life events are documented risk factors for antenatal anxiety and depression, preterm birth and birth weight. We aimed to asses whether the adverse effects of prior negative life events increase with lower socioeconomic status and which aspects of socioeconomic status are most relevant.

Residence background,socioeconomic status,and fertility

Previous research has demonstrated that socioeconomic differentials in fertility are heavily influenced by couples with rural background. These studies show an inverse relationship between fertility and socioeconomic status for couples of rural background, but no relationship for urbanorigin couples. The effect of urban background on rural fertility differentials has not been examined. This study investigates the potential effect of urban-origin couples on socioeconomic differences in fertility in rural areas. Data from the 1967 Survey of Economic Opportunity are analyzed to show that rural socioeconomic fertility differences are not influenced by the presence of persons of urban background.     

城市化、人口红利与日本经济增长关系研究

20世纪60年代后,日本经济飞速发展,"人口红利"在经济增长重要战略机遇期起着举足轻重的作用,这一作用的发挥离不开日本快速的城市化进程。20世纪90年代后,日本的"人口红利"逐渐式微并向少子老龄化社会迈进,但这并不意味着人口红利的结束,居民储蓄、老年人再就业、人力资本积累的增长或将推动"第二次人口红利"的出现。中国作为人口大国,其经济增长模式和人口转变模式与作为经济大国的日本都呈现出相似的情形,对日本的研究可以为中国未来发展提供重要的借鉴,中国应充分利用当前的"人口红利"并促使"第二次人口红利"的实现,延长人口红利作用期以保证经济增长的持续性。
