Inferring Directional Migration Propensities from the Migration Propensities of Infants in the United States

Beginning with the 2010 decennial census, the U.S. Census Bureau plans to drop its long-form questionnaire and to replace it with the American Community Survey (ACS). The resulting absence of the larger sample provided by the census count will complicate the measurement and analysis of internal migration flows. In addition, the strategy of averaging accumulated samples over time will mix changing migration patterns. The migration question will refer to a one-year time interval instead of the five-year interval used in the censuses between 1960 and 2000, complicating historical comparisons and the production of multiregional projections based on five-year age groups. Consequently, students of territorial mobility increasingly will find it necessary to complement or augment possibly inadequate data collected on migration with estimates obtained by means of “indirect estimation.” A method is presented that allows one to infer age-specific directional migration propensities at the regional level from birthplace-specific infant population data, which approximates infant migration propensities, and from these infers the migration propensities of all other ages. The method is applied to at the nine-division spatial scale.     

中国人口的迁移转变——基于迁移率的考察

经典人口转变理论侧重死亡和生育转变过程的测量、描述和解释,地理学家将迁移转变纳入人口转变框架,以完善人口转变理论。不过与死亡和生育转变研究不同,中国的迁移研究侧重基于对迁移流动人口规模和结构的考察分析,少有采用人口学意义上的迁移率指标的研究。文章利用2010—2015年历次中国综合社会调查的合并数据,通过人口学方法和泊松回归模型,计算和分析了1950—2015年中国人口迁移率趋势及社会经济差异。中国的迁移转变在宏观趋势上与中国的政治经济变迁高度一致。与死亡和生育转变相比,其波折性更强,说明更易受到经济社会政策变化的冲击。同时也观察到逢“0”和逢“5”年份的申报偏好。另外,迁移的社会经济差异明显。男性迁移率高于女性,但是两性差异在不断缩小;乡城迁移和未婚迁移大幅度增长;而越来越多受教育程度较高人群加入迁移,使得受教育程度越高的人群具有越高的迁移率。可以认为基于迁移率的考察揭示了中国迁移转变更具体生动的过程。     

Migration of the poor

One aspect of migration which has been largely overlooked by researchers is the migration of people receiving public assistance benefits. The migration, or lack of migration, of these people has clear policy implications. Poor people put numerous demands on the locality where they reside, including demands for welfare benefits. The research presented in this paper reveals that movers receiving AFDC payments are able to improve their economic standing more than those who do not move. It is also shown that states with a net in-migration of public assistance recipients but net out-migration of non-recipients do have higher benefit levels than states with net out-migration of recipients and net in-migration of non-recipients. Employment and income data do not show the same differences between the state types.     

流动人口家庭迁居的经济决策

文章在家庭"理性人"假设的基础上构建家庭迁居的经济决策模型,对家庭的迁居决策进行实证分析。研究发现,家庭通过对迁居的货币价值进行精确衡量,在不同生命周期阶段、不同的家庭结构类型的条件下,形成不同的迁居行为。在家庭实际迁居的过程中,为了维持家庭的抚养、赡养等功能,家庭的迁居策略可能并非最优化的经济决策。流动家庭会将部分社会成本进行内部消化,以减少流动行为对传统家庭功能的削弱。     

Internal Migration and Development: Comparing Migration Intensities Around the World

Migration is the principal demographic process shaping patterns of human settlement, and it serves an essential role in human development. While progress has been made in measuring international migration, internal migration statistics are as yet poorly developed in many countries. This article draws on a repository of data established under the IMAGE (Internal Migration Around the GlobE) project to address this deficit by constructing the first comprehensive league table of internal migration intensities for countries around the world. We review previous work, outline the major impediments to making reliable comparisons, and set out a methodology that combines a novel estimation procedure with a flexible spatial aggregation facility. We present the results in the form of league tables of aggregate crude migration intensities that capture all changes of address over one‐year or five‐year intervals for 96 countries, representing four‐fifths of the global population. Explanation for the observed differences has been sought, inter alia, in historical, structural, cultural, and economic forces. We examine the links between development and migration intensity through simple correlations using a range of demographic, economic, and social variables. Results reveal clear associations between internal migration intensities and selected indicators of national development.

中国人口终身迁移状况分析

“出生地”是用来收集人口迁移信息最常用的调查项目之一。中国以往的人口普查中一直缺少这一调查项目 ,这使得利用出生地资料对人口迁移状况进行分析在国内一直是个空白。中国第五次人口普查在中国人口普查史上首次调查了人口的出生地信息。本文主要根据第五次人口普查提供的出生地资料 ,对中国各省人口的终身迁移水平、流向以及不同年龄人口的终身迁移状况进行了初步分析。     

农村劳动者流动中的几个问题

在中国现有的研究和相关的政策建议中,流动常常都被看做是缓解乡村"剩余"人口(劳动者)压力的一种方法,也是实现现代化的一种主要手段。换句话说,乡村被看做中国现代化的主要障碍之一,它带来的更多是问题而不是解决问题的方法。作者提出,研究人员和决策者应该更多地考虑农村外出劳动者对于流出地发展所做的重要贡献。     

Migration in market and democracy transition: Migration intentions and behavior in Romania

This paper analyzes the determinants of migration decision-making in the context of recent market and democratic transition in Romania. Using early 1990s internal migration survey, census and population register data, the results from Lisrel path models show that market and democracy value orientation variables are significant determinants of intentions to move, controlling for individual and regional social structural and resource indicators. Similarly, district-level out-migration behavior is directly determined by the political profile of the local area. Results from the total and disaggregated rural and urban models are interpreted through a reform values and characteristics typology of migrants. At least in the early stages of Romanian transition, the results indicate that migration choice behavior is governed by a search for places with greatest opportunities in terms of market and democracy returns. Implications of the results for political system and public policy decision are discussed.     

中国清朝中期的人口迁移

清朝中叶,随着社会经济的恢复与发展,人口迅速增长起来,形成我国历史上第一个人口增长的高峰,人多地少的矛盾日益突出。为缓解严重的人口压力,失地农民和手工业者在无法生存的情况下被迫构成人口迁移的主力,由人口稠密地区向人口稀疏地区、由农村向商业经济发达的城市流动,使清中期的人口迁移出现新的特点及趋势。     

Causality Chains in the International Migration Systems Approach

Research into international migration lacks a commonly accepted theoretical framework, which would facilitate the accumulation of knowledge. This article aims to be a first attempt to construct such a framework and to incorporate causalities in the international migration systems approach. The author presents a theoretical framework in which four groups of factors acting on international migration are distinguished: economic, social, political and “linkages.” The causalities in this framework are derived from different international migration theories. The various positions of these whole theories within the framework are shown as causality chains. In a way, these causality chains form the time dimension of an international migration system

Migration as Social Movement: Voluntary Group Migration and the Crimean Tatar Repatriation

Voluntary group migration occurs when a collectivity reaches a group‐level decision to migrate and does so as a community without external compulsion. Typical examples include collective settler movements and voluntary repatriations of refugee communities. We demonstrate the distinctive characteristics of voluntary group migration that make it hard to analyze with current migration theories, and we develop an initial theoretical framework identifying the conditions that typically produce this type of population flow. Recognizing the collective nature of the mobilization that leads to voluntary group migration, we turn to social movement theory as a source of analytical tools that, in combination with concepts offered by prior migration theories, help us build an initial theory. To illustrate our ideas, we discuss an especially revealing contemporary case: the resettlement of Crimean Tatars to their original homeland.     

城乡劳动力流动与迁移回报率

本文从微观主体人力资本投资的角度来理解中国农村劳动力流动现象。提出应该将迁移作为一种投资方式单独进行考察。通过讨论迁移的预期成本和收益,发现与教育投资相比,迁移能得到较高的回报率,迁移回报率是吸引农村劳动力选择迁移流动到城市的重要因素。由此得出结论：农村劳动力向城市的迁移是一种理性选择的人力资本投资方式。要改变中国二十年来农村劳动力以低教育水平、低收入水平为特征的循环流动。必须尽快改善农村的人力资本投资环境。特别是教育环境．     

Family Migration Pattern in China

Do an increase in ageing in developed countries and ＂getting old before getting rich＂ in developing countries indicate that fluctuations in the population age structure have produced a qualitative change？ What is a qualitative change and what is a quantitative change＇？ Here we propose a new concept of Shadow Population,then establish a new standard for evaluating population age structure,finally present a typical five stage population age structure type transition model. The model simulation shows that all world regions are still in the adult stage and that population ageing belongs to the category of quantitative change. However, sustained low fertility will lead to a qualitative change in the ageing population. The current pressure of population aging in the adult stage placed on the pension security system shows that this system is truly not retirement age and Long-term stability in a sustainable system,Gradually raising the replacement fertility is the key to solving the socioeconomic development dilemma presented by future population ageing in low fertility regions or cotlntries,but the latter is more urgent.     

Change in Chinese Population Migration

Presently, China is experiencing the largest population migration in history. This flowing population has caused a widespread concern.     

Migration and fertility in Ticino

Summary Migration in the Swiss canton of Ticino is one example of the wide variety of demographic systems that existed in pre-industrial Europe. The continuous movement of men was a consequence of economic, social and geographic conditions which restricted the demand for labour. Seasonal migration and overseas migration were both sex and age selective. They resulted in an imbalance of the sex ratio and a remarkably low female nuptiality. They also reduced fertility within marriage by separating husbands and wives during their childbearing years. The effect of long, medium and short-term migration on fertility can be isolated from census and vital registration sources.     

我国人口迁移过程中的空间效应实证研究

在引力方程的框架下,基于O?D模型,针对现有研究忽视空间效应的现状,利用空间计量方法对我国人口迁移中的空间效应进行了实证研究。分析结果表明,引入空间效应后,不仅能够较好地解释我国人口在省际间的迁移,而且可以更深入地了解我国现阶段各省区间人口迁移的机制和方式。这不但是对人口迁移理论的有益扩展,对我国东西部地区人口合理流动,协调区域经济发展更是具有深刻的意义。     

Second-Generation Outcomes of the Great Migration

The mass migration of African Americans out of the South during the first two-thirds of the twentieth century represents one of the most significant internal migration flows in U.S. history. Those undertaking the Great Migration left the South in search of a better life, and their move transformed the cultural, social, and political dynamics of African American life specifically and U.S. society more generally. Recent research offers conflicting evidence regarding the migrants’ success in translating their geographic mobility into economic mobility. Due in part to the lack of a large body of longitudinal data, almost all studies of the Great Migration have focused on the migrants themselves, usually over short periods of their working lives. Using longitudinally linked census data, we take a broader view, investigating the long-term economic and social effects of the Great Migration on the migrants’ children. Our results reveal modest but statistically significant advantages in education, income, and poverty status for the African American children of the Great Migration relative to the children of southerners who remained in the South. In contrast, second-generation white migrants experienced few benefits from migrating relative to southern or northern stayers.
