Environmental hazard and migration intentions in a coastal area in Ghana: a case of sea flooding

Recently, there has been significant debate about whether ‘environmental migration’ can constitute a form of adaptation to environmental change, as opposed to forced or flight migration. The Foresight Report on Migration and Environmental Change (2011) suggested environmental factors are one driver of migration, as well as political, social, economic and demographic drivers, and that—under the right conditions—migration can be a form of adaptation to changing climatic conditions. However, this is dependent on migrants having adequate social and financial capital to undertake beneficial types of migration; it further argues that environmental change may result in ‘trapped populations’ whereby people who lack the necessary resources to re-establish livelihoods elsewhere may be left exposed to increasingly severe environmental shocks and stresses in situ. Research on the climate-migration nexus in West Africa has largely focused on out-migration from the semi-arid Sahel with more limited evidence about how sea flooding interacts with migration flows. This paper attempts to help fill this knowledge gap. Using data from a representative survey of households across three coastal communities in Ghana’s Volta River Delta, this paper concludes that exposure to sea flooding may not be a primary cause of out-migration as other community, economic and political factors influence migration intentions and decisions. Thus, it is important for planned adaptation interventions to be strengthened in situ to enable households, particularly farming households, sustain their livelihoods.     

Age,education and occupation differentials in interregional migration: Some evidence for Canada

This paper attempts to bring together the demographic literature on differential migration with economic analysis of regional labor mobility. This is done by estimating a rather simple form of economic model of migration by means of linear regression analysis for specific age, education and occupation groups of male interprovincial migrants in Canada. The data on migration are from the population sample of the 1961 Census of Canada. The pattern of migration differentials displayed by these data is broadly similar to that observed in the United States and elsewhere. The regression results suggest that differential migration by education and occupation groups may be accounted for by the varying responsiveness of the various groups to economic gains obtained through migration. While this seems to be generally true of age differentials as well, the relationship of those to regional income differentials is weaker and points up an important role of motivations other than economic gain.     

Is There an Urban Advantage in Child Survival in Sub-Saharan Africa? Evidence From 18 Countries in the 1990s

Evidence of higher child mortality of rural-to-urban migrants compared with urban nonmigrants is growing. However, less attention has been paid to comparing the situation of the same families before and after they migrate with the situation of urban-to-rural migrants. We use DHS data from 18 African countries to compare child mortality rates of six groups based on their mothers’ migration status: rural nonmigrants; urban nonmigrants; rural-to-urban migrants before and after they migrate; and urban-to-rural migrants before and after they migrate. The results show that rural-to-urban migrants had, on average, lower child mortality before they migrated than rural nonmigrants, and that their mortality levels dropped further after they arrived in urban areas. We found no systematic evidence of higher child mortality for rural-to-urban migrants compared with urban nonmigrants. Urban-to-rural migrants had higher mortality in the urban areas, and their move to rural areas appeared advantageous because they experienced lower or similar child mortality after living in rural areas. After we control for known demographic and socioeconomic correlates of under-5 mortality, the urban advantage is greatly reduced and sometimes reversed. The results suggest that it may not be necessarily the place of residence that matters for child survival but, rather, access to services and economic opportunities.

The Internetization of International Migration

The Internet has revolutionized our economies, societies, and everyday lives. Many social phenomena are no longer the same as they were in the pre‐Internet era: they have been “Internetized.” We define the Internetization of international migration, and we investigate it by exploring the links between the Internet and migration outcomes all along the migration path, from migration intentions to actual migration. Our analyses leverage a number of sources, both at the micro‐ and the macro‐level, including the Gallup World Poll, the Arab Barometer, data from the International Telecommunication Union, the Italian population register, and unique register data from a migrant reception center in Southern Italy. We also distinguish between economic migrants—those who leave their country of origin with the aim of seeking better economic opportunities elsewhere—and political migrants—those who are forced to leave their countries of origin for political or conflict‐related reasons. Our findings point to a consistently positive relationship between the diffusion of the Internet, migration intentions, and migration behaviors, supporting the idea that the Internet is not necessarily a driving force of migration per se, but rather an enabling “supportive agent.” These associations are particularly relevant for economic migrants, at least for migration intentions. Further analyses underscore the importance of the Internet in providing a key informational channel which helps to define clearer migration trajectories.     

Immigrant migration dynamics model for The Netherlands

In this paper, we analyze the demographic factors that influence the migration dynamics of recent immigrants to The Netherlands. We show how we can allow for both permanent and temporary migrants. Results disclose differences among migrants by migration motive and by country of origin and lend support to our analytical framework. Combining both models, for departure and returning to The Netherlands, yields a framework for predicting the migration dynamics over the life-cycle. From the obtained insight in the dynamic composition of migrants in the country, important policy implications can be derived.     

Who moves and who stays? Rural out-migration in Nigeria

Data from the nationally representative 1993 Migration and Urbanization Survey of Nigeria are used to simultaneously examine the patterns of rural-rural and rural-urban migration in Nigeria. A multinomial logistic regression model predicts the independent and collective association between individual, household, and regional variables and migration from rural areas to rural and urban destinations. Associations between education, religion and ethnicity and migration propensities exist at the national level. The Kanuri-Shua Arabs are generally non-migrants, the Hausa-Fulani and Yoruba are predominantly rural-rural migrants and the Igbo-Ibibio and Urhobo-Isoko-Edo are predominantly ruralurban migrants. Christians are significantly more mobile than Muslims. While the highly educated are most likely to choose an urban destination, a significant proportion migrate to other rural areas. Concern over population concentration is not supported, as rural migrants move to all regions and to urban and rural areas.     

Internal Migration and Life Satisfaction: Well-Being Paths of Young Adult Migrants

Internal migration is typically associated with higher income, but its relation with life satisfaction remains unclear. Is internal migration accompanied by an increase in life satisfaction and does this increase depend on the reason for moving? What are the aspects of life underlying overall life satisfaction that change following migration? These questions are addressed using longitudinal data from the Swedish Young Adult Panel Study. Migration is defined as a change in municipality of residence. Comparing migrants to non-migrants, it is found that internal migration is accompanied by a short to medium term increase in life satisfaction for those who move due to work (work migrants), as well as those who move for other reasons (non-work migrants). However, only work migrants display an improvement in life satisfaction that remains significant 6 or more years following the move. Work and non-work migrants also differ in the aspects of life that change following migration. For work migrants the move is accompanied by an improvement in occupational status positively associated with well-being 6–10 years after the move. For non-work migrants, a persisting increase in housing satisfaction follows migration, but this housing improvement is accompanied by only a short to medium term increase in overall well-being.     

A summary analysis of the 3rd inquiry

20 ESCAP member countries responded to the "Third Population Inquiry among Governments: Population policies in the context of development in 1976." The questionnaire sent to the member countries covered economic and social development and population growth, mortality, fertility and family formation, population distribution and internal migration, international migration, population data collection and research, training, and institutional arrangements for the formulation of population policies within development. Most of the governments in the ESCAP region that responded indicate that the present rate of population growth constrains their social and economic development. Among the governments that consider the present rate of population growth to constrain economic and social development, 13 countries regarded the most appropriate response to the constraint would include an adjustment of both socioeconomic and demographic factors. 11 of the governments regarded their present levels of average life expectancy at birth "acceptable" and 7 identified their levels as "unacceptable." Most of the governments who responded consider that, in general, their present level of fertility is too high and constrains family well-being. Internal migration and population distribution are coming to be seen as concerns for government population policy. The most popular approaches to distributing economic and social activities are rural development, urban and regional development and industrial dispersion. There was much less concern among the governments returning the questionnaire about the effect of international migration than internal migration on social and economic development.     

Internal migration: why do Filipinos move?

The rapid movement of Filipinos from 1 part of the Philippines to another is not a new phenomenon, but mobility has been increasing. A study conducted by Peter C. Smith revealed that interprovincial lifetime mobility of the national population increased from 15.8% in 1960 to 17.6% in 1970, while interregional mobility increased from 12.7% to 13.4%. People still disagree as to whether the size and rate of growth of the population are excessive, but there seems to be total consensus as regards its spatial imbalance. Because internal migration appears to be an important factor in national development, a need exists to examine different aspects of internal migration, such as the directions taken by migration flows, the migrants' reasons for moving, the migrants' characteristics, the migrants' success or lack of success at their places of destination, the social problems accompanying internal migration, effforts to deal with the problems caused by internal migration, and the implications of migration trends for policy and for the country's development programs. The most dominant migration trend in the Philippines in recent years has been toward the urban, or more accurately the suburban, areas adjacent to Metropolitan Manila. The city of Manila itself suffered a net outflow, further pointing to the trend toward suburbanization. Migration flows are primarily caused by economic reasons. About one half the sample of a Filipinas Foundation Study moved to provinces other than the province of birth in the pursuit of employment and other economic opportunities. A study of the country's migrant population age 15 and older showed that 53% of migrants were female. For male migrants, age ranges from 20-40; it ranges from 15-35 for females. Where cash income is concerned, migrants in Pernia's study of rural urban migration were better off than nonmigrants. Migrants were, on the average, as well off as native urbanites or metropolitanites. Among the more significant points raised by scholars and researchers are the following: urbanization is an inevitable and irreversible process, and it is wise to plan for it; the problem is not rapid urbanization but unbalanced urbanization, i.e., the concentration of urbanization in Metro Manila; steps to alter national urban patterns might include establishing a migration guidance office; the need exists for an explicit, firm, and consistent population distribution policy; and solutions that anticipate problems having to do with internal migration and prevent these problems from arising will, in the long run, be more effective than curative solutions.     

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。     

流动人口在城市劳动力市场中的地位:三群体研究

关于流动人口在城市劳动力市场中的地位问题,过去已有大量文献,但研究重点是农民工。这里把外来市民纳入观察视野,利用2008年"迁移和流动劳动力与中国大城市发展"调查数据,分析工资收入和社会保险参与的影响因素。主要研究发现:在工资收入上,不同户籍身份劳动者之间没有净差异;在养老保险和工伤保险参与上,本市居民、外来市民和农民工参与的可能性依次递减。这意味着,工资收入已经基本上由劳动力市场决定,而社会保险参与依然与户籍身份有关。不过,这种关联方式已经从过去的城乡户籍身份歧视转向本地/非本地权益差异。     

地区发展、经济机会、收入回报与省际人口流动

利用最新的第六次全国人口普查数据,本文考察了省际人口流动的空间模式,发现省际人口流动呈现明显的空间聚集态势.并进一步分析地区差异对省际人口流动的影响,结果表明：作为流出地,一个地区的经济发展水平对于人口流出具有显著的阻力效应,但经济机会的多寡和经济回报的高低并无显著的影响;作为流入地,一个地区的经济发展水平对于吸引人口流入并不具有显著的影响,其“拉力”主要表现为经济机会的多寡和经济回报的高低.因地区发展不平衡短期内难以改变、经济开放性会继续增强、收入地区分化仍将存在,加上更加自由的流动环境和不断改善的交通和通讯条件,省级人口流动在局部地区集中的趋势将会进一步被强化.     

Causes of Urban Migration in Bangladesh: Evidence from the Urban Health Survey

Mass migration is increasing urban populations globally. One country where urban migration is significantly increasing is Bangladesh, where systematic research will explore the reasons for urban migration in order to devise policies in this area, including maintaining the balance of urban–rural developments. This study used the Urban Health Survey (UHS) 2013 to ascertain the reasons for urban migration in large divisional cities in Bangladesh. The 2013 survey examined the differences between male and female migration, alongside any significant sociodemographic factors that might contribute to their motivation for moving to the city. The survey revealed that a majority of women (64.8%) migrated for family purposes, for example, joining husbands or in-laws, or parents/children. However, in recent years, female migrants have been involved in income-generating activities mostly due to a recent garment-making boom in Dhaka and its suburbs. A higher proportion of men (85.3%) moved to urban areas for work-related reasons: searching for new jobs, better income, or transfer in services. Among the sample in this study, 77% of the respondents (79.3% female and 73.5% male) migrated from villages. This migration mostly centered on Dhaka, the capital city of Bangladesh, where 68.1% of the total study sample migrated followed by 15.7% who went to Chittagong. The results indicate that the contemporary urban-centered economic policy in Bangladesh might require revision to accommodate the increased migrants from rural areas.

     

Volume,characteristics and consequences of internal migration in Colombia

More than one-third of the Colombian population can be classified as migrants. The prevailing direction of movements is urbanwards, yet it is significant that better than a third of all movements are to rural destinations. Nationwide comparisons of migrants and residents on demographic characteristics would indicate that all streams are selective of the younger and unmarried population, with women predominating in urbanwards movements and men in those to rural areas. However, when compared in terms of socioeconomic characteristics, migrants are more sharply differentiated among themselves than they are from the resident population at each of their respective destinations. Within the migrant population, a natural funneling of the more able migrants to the largest centers suggests itself. Migrants have consistently higher activity rates than the remainder of the population and, in the case of men at least, appear capable of competing for jobs on an equal basis with residents at their respective destinations. Female migrants, however, are consistently overrepresented in lower-status activities, particularly in domestic services.     

流动人口社会保险参与状况的地区差异分析——基于2011年全国32个省级单位的流动人口问卷调查

为了促进各地区流动人口社会保险参与状况平衡发展,本文运用国家人口计生委于2011年7月在全国32个省级单位开展的流动人口问卷调查数据,对流动人口的社会保险参与状况进行地区归类和差异分析。结果显示,32个地区流动人口的社会保险可归结为高参与、中参与、低参与三种类别。低参与地区涵盖了大部分西部和中部省份,中参与地区涵盖了一半的东部省份和1/3的中部省份,而高参与地区涵盖了另一半较为发达的东部省份和2个条件较好的西部省份。结合地区差异分析结果可知,相较而言,东部地区的社会保险参与状况较好,其次为中部,而西部较差。进一步从流动人口的相关特征来看,社会保险参与状况的地区差异与各类地区流动人口的社会基本情况、流动过程、家庭状况和就业特征等方面存在依存关系。     

中国农村地区的家庭禀赋与外出务工劳动力回流

中国农村地区家庭禀赋对个人的行为决策有着重要的影响,需要学术界予以更多的关注。为了考察外生性的家庭禀赋对劳动力就业流动的影响,文章通过构建新生代外出务工劳动力和户主子女的回流决策两个计量模型来进行经验论证。分析结果表明,农村劳动力的迁移选择是综合考虑家庭禀赋状况的理性决策,尤其是对于年轻一代的外出劳动力。家庭经济资本的增加会阻碍家庭外出务工成员的回流。外出劳动力回流的概率起初随着家庭人力资本和家庭自然资本的增长而上升,达到一定程度后开始下降。家庭成员只有拥有较为丰富的人力资本,外出务工劳动力才能对家庭社会资本加以充分利用。另外,分析显示年轻一代劳动力和第一代劳动力对家庭社会资本和自然资本的利用是有差异的。     

改革开放后北京、上海、广州对流动人口的经济拉力因素的分析

本文以推拉理论建立多元线性模型并运用逐步回归的方法,分析改革开放后北京、上海、广州吸引流动人口流入的经济因素。结果显示流动人口主要依据微观经济因素做出流动迁移决策;不同城市对流动人口产生拉力的具体的微观经济因素不尽相同,即使有相同经济拉力因素的城市,拉力的大小也有差异;三城市的流动人口就业的分布不同,广州流动人口就业集中分布于第三产业,北京和上海则不然。     

农村大龄未婚男性的生活质量及其影响因素分析——以冀北地区调查为基础

利用2010年冀北C县农村调查数据,借鉴生活质量的概念和研究框架,分析农村大龄未婚男性的生活质量现状及影响因素。研究结果表明,与已婚男性相比,未婚男性的客观生活质量和主观生活质量均明显偏低;居住方式和父母在世情况显著影响他们所获得的生活支持,工作、收入和社会保障显著影响他们的经济满意度;年龄、生理、心理和收入是影响未婚男性生活总体满意度的重要因素。经济满意度和生活总体满意度之间具有显著的正向相关关系,社会交往满意度和生活总体满意度之间的关系不显著。分析农村大龄未婚男性的生活质量有利于把握其生存状态,也有利于理解其对社会公共安全的影响。     

Implications of boundary choice for the measurement of residential mobility

Analyses of residential mobility are usually conditioned on a system of geography in which territory is divided into discrete units. Types of movement are defined in terms of these units, the most important distinction being that between local mobility and migration. Here we examine explicitly the implications of the choice of the migration-defining boundary in the U.S. over the 1940-1980 period. We demonstrate how boundary choice influences the extent and character of selectivity of the mobile population by using demographic and social characteristics. It appears that over time the state line may be replacing the county line in distinguishing kinds of migrants. Further, our results point to a growing fraction of footloose migrants, not tied to local territory, identified by their migration history rather than demographic characteristics.
