California Exodus? A Network Model of Population Redistribution in the United States

Motivated by debates about California's net migration loss, we employ valued exponential-family random graph models to analyze the inter-county migration flow networks in the United States. We introduce a protocol that visualizes the complex effects of potential underlying mechanisms, and perform in silico knockout experiments to quantify their contribution to the California Exodus. We find that racial dynamics contribute to the California Exodus, urbanization ameliorates it, and political climate and housing costs have little impact. Moreover, the severity of the California Exodus depends on how one measures it, and California is not the state with the most substantial population loss. The paper demonstrates how generative statistical models can provide mechanistic insights beyond simple hypothesis-testing.

Time to Mainstream the Environment into Migration Theory?

As with all social processes, human migration is a dynamic process that requires regular theoretical reflection; this article offers such reflection as related to the role of the natural environment in contemporary migration research and theory. A growing body of evidence suggests that environmental contexts are increasingly shifting social and ecological realities in ways that are consequential to migration theory. We review some of this evidence, providing examples applicable to core migration theories, including neoclassical economic and migration systems perspectives, the "push-pull" framework, and the new economics of labor migration. We suggest that neglecting consideration of the natural environment may yield misspecified migration models that attribute migration too heavily to social and economic factors particularly in the context of contemporary climate change,. On the other hand, failure to consider migration theory in climate scenarios may lead to simplistic projections and understandings, as in the case of "climate refugees". We conclude that migration researchers have an obligation to accurately reflect the complexity of migration's drivers, including the environment, within migration scholarship especially in the context of global climate change.

The macro-contextual drivers of the international mobility of managers and executives

Purpose

The purpose of this paper is to assess the country-level drivers of managers' and executives' mobility. Both sub-groups play a fundamental role in entrepreneurship, innovation and ultimately on wealth creation in destination countries. The objective is to capture how the impact of economic, cultural and institutional factors differ for these sub-groups’ vis-a-vis the broad highly skilled group's mobility.

Design/methodology/approach

The paper investigates the country-level drivers of managers' and executives' bilateral migration from 190 countries to 32 Organisation for Economic Co-operation and Development (OECD) countries. It builds a model on four macro-contextual attractiveness factors of destination countries: economic conditions, cultural affinity, institutions and quality of life. The authors use fixed-effects regressions and carry several model specifications comparing the impact of different attractiveness factors on the migration of lower skilled, highly skilled, managers and executives.

Findings

The authors find that economic incentives do not motivate managers' or executives' mobility. The quality of life is more significant in driving executives' mobility than economic measures are. Cultural affinity, institutions and quality of life are more important for managers. Ethnic relations are significant for the overall highly skilled sample.

Practical implications

These results have implications for global companies interested in recruiting managers and executives and their recruitment strategies. International businesses attempting to maximize their access to international managers, for instance, can develop recruitment packages that capitalize on the particularities of the quality of life of the potential destination country. Such packages can contribute to streamlining the process and focusing on candidates' needs to increase the likelihood of relocation. The study’s results, in addition, have policy implications in terms of the “branding” of countries whose aim is to attract managers and other highly skilled talent. Officials can build an effective country-branding strategy on the existence of ethnic networks, effective institutions and quality of life to attract a particular segment of the talent pool. For instance, they can develop a strategy to attract executives by focusing on a specific cultural characteristic and elements of the quality of life such as the effectiveness of their country's healthcare and education systems.

Social implications

The paper also points out to the issues that policymakers must resolve in the absence of an education system that guarantees the talent pool that the economy needs. For those countries that rely on foreign talent (such as Switzerland, Singapore and the USA), it is paramount to promote safety, quality of life and institutional development, in order to guarantee a sufficient inflow of talent.

Originality/value

Most global studies focus on the complete migrant stock or on highly skilled workers in particular. The authors disaggregate the sample further to capture the drivers of managers' and executives' migration. The authors find that latter sub-groups respond to different country-level attractiveness factors compared to the broader highly skilled sample. In doing so, the authors contextualize the study of mobility through a positively global lens and incorporate the impact of some of the factors generally overlooked.

Flows of Substances in Networks and Network Channels: Selected Results and Applications

This review paper is devoted to a brief overview of results and models concerning flows in networks and channels of networks. First of all, we conduct a survey of the literature in several areas of research connected to these flows. Then, we mention certain basic mathematical models of flows in networks that are based on differential equations. We give special attention to several models for flows of substances in channels of networks. For stationary cases of these flows, we present probability distributions connected to the substance in the nodes of the channel for two basic models: the model of a channel with many arms modeled by differential equations and the model of a simple channel with flows of substances modeled by difference equations. The probability distributions obtained contain as specific cases any probability distribution of a discrete random variable that takes values of 0,1,…. We also mention applications of the considered models, such as applications for modeling migration flows. Special attention is given to the connection of the theory of stationary flows in channels of networks and the theory of the growth of random networks.

Using Social Networks to Sample Migrants and Study the Complexity of Contemporary Immigration: An Evaluation Study

We test the effectiveness of a link-tracing sampling approach-network sampling with memory (NSM)-to recruit samples of rare immigrant populations with an application among Chinese immigrants in the Raleigh-Durham area of North Carolina. NSM uses the population network revealed by data from the survey to improve the efficiency of link-tracing sampling and has been shown to substantially reduce design effects in simulated sampling. Our goals are to (1) show that it is possible to recruit a probability sample of a locally rare immigrant group using NSM and achieve high response rates; (2) demonstrate the feasibility of the collection and benefits of new forms of network data that transcend kinship networks in existing surveys and can address unresolved questions about the role of social networks in migration decisions, the maintenance of transnationalism, and the process of social incorporation; and (3) test the accuracy of the NSM approach for recruiting immigrant samples by comparison with the American Community Survey. Our results indicate feasibility, high performance, cost-effectiveness, and accuracy of the NSM approach to sample immigrants for studies of local immigrant communities. This approach can also be extended to recruit multisite samples of immigrants at origin and destination.

Environmental inequality in the neighborhood networks of urban mobility in US cities

Exposure to air pollution within one’s residential neighborhood has detrimental consequences on health and well-being. Yet, this effect may be mitigated or exacerbated because individuals spend much of their time outside of their residential neighborhood to travel to neighborhoods across a city for work, errands, and leisure. Using mobile phone data to track neighborhood mobility in large US cities, I find that residents from minority and poor neighborhoods travel to neighborhoods that have greater air pollution levels than the neighborhoods that residents from White and nonpoor neighborhoods visit. These results reveal that minority and poor residents face environmental inequalities at three geographic scales: the neighborhoods they live in, their bordering neighborhoods, and the neighborhoods they visit.

Research has made clear that neighborhoods impact the health and well-being of their residents. A related strand of research shows that neighborhood disadvantage is geographically clustered. Because the neighborhoods of low-income and minority populations tend to be more disadvantaged, neighborhood conditions help explain racial and socioeconomic inequalities. These strands of research restrict processes of neighborhood influence to operate only within and between geographically contiguous neighbors. However, we are underestimating the role of neighborhood conditions in explaining inequality if disadvantage extends beyond the residential and extralocal environments into a network of neighborhoods spanning the urban landscape based on where residents move within a city. I use anonymized mobile phone data to measure exposure to air pollution among residents of poor and minority neighborhoods in 88 of the most populous US cities. I find that residents from minority and poor neighborhoods travel to neighborhoods that have greater air pollution levels than the neighborhoods that residents from White and nonpoor neighborhoods visit. Hispanic neighborhoods exhibit the greatest overall pollution burden, Black/White and Asian/White disparities are greatest at the network than residential scale, and the socioeconomic advantage of lower risk exposure is highest for residents from White neighborhoods. These inequalities are notable given recent declines in segregation and air pollution levels in American cities.

Examining migration governance: evidence of rising insecurities due to COVID-19 in China, Ethiopia, Kyrgyzstan, Moldova, Morocco, Nepal and Thailand

The COVID-19 pandemic has significantly changed the context of global migration. From a migration perspective, the pandemic is a source of insecurities that challenge migrants, their livelihoods and migration governance. Meanwhile, curtailment in movement has led to economic decline affecting labour markets. For migrant origin and hosting countries, this poses multidimensional development challenges. Analysis from March to August 2020 of China, Ethiopia, Kyrgyzstan, Moldova, Morocco, Nepal and Thailand highlights the varying ways in which they are all severely affected by the disruptions in migration, suggesting a potentially emerging complex situation in migration patterns and pathways. The disruptions in migration and remittances have had a profound impact on migrants and migrant-sending households. The uncertainty of migration returning to pre-pandemic levels and the potential of lasting consequences on migrants and migration patterns and pathways, suggests a future of greater risk and exploitation, and a wider gap between formal and informal migration. This paper calls for greater mobility cooperation between countries and suggests strengthening mobility migration frameworks and policies for safer migration and for the rights of migrants.

Socioeconomic Status Changes of the Host Communities after the Rohingya Refugee Influx in the Southern Coastal Area of Bangladesh

The refugee influx from Myanmar, known as Rohingya refugees, is a serious concern for global refugee issues. Bangladesh currently hosts one million Rohingya refugees in the coastal district of Cox’s Bazar. Considering the number of the refugees, in addition to the humanitarian concerns, they are also creating pressure on the local host communities. This study explored the socioeconomic changes of the host communities after the refugee influx. In order to fulfill this study’s objectives, 35 villages near the Rohingya refugee camps from the coastal district of Bangladesh were surveyed. In the villages, 10% of households were surveyed in 2016 and also in 2020, covering 1924 and 2265 households, respectively. A temporal comparison of the host community’s socioeconomic status between 2016 and 2020 was conducted in order to determine the changes after the recent refugee influx. This study found that the local community’s socioeconomic status degraded. The annual income decreased by 24%, which is unusual for a country with over 6% gross domestic product (GDP) growth in recent times. The income decreased from all livelihood options except farming, which could be related to the availability of cheap labor and the high demand for commodities. The villages were clustered using k-means, and 20 villages were found to be affected after the refugee influx with degraded socioeconomic status. The host community’s general perception was initially positive, but later turned negative toward the refugees. This study will be important for the government and donor agencies to develop strategies to properly manage the refugee camps and adjacent host communities.

When does Social Capital Matter for Migration? A Study of Networks, Brokers, and Migrants in Nepal

The study of social capital has been one of the strongest areas of recent advance in migration research, but there are still many questions about how it works and why it has varying effects in studies of different places. In this article, we address the contextual variation in social capital's effects on migration by considering migration brokers. We argue that destinations for which migration is logistically difficult to arrange give rise to brokerage industries and hypothesize that brokers in turn substitute for the informational capital typically provided by social networks. Our empirical tests in Nepal support this narrative, showing that social networks matter for migration to destinations where brokers are not available and have little discernible effect on migration to brokered destinations. Our results suggest that migration research should consider the growing role of brokerage agencies, that theorizations of social capital more broadly must contend with how it is delimited by brokers, and that social scientists might also consider other consequences that can arise from these migration brokers that are increasingly common in many countries and provide a marketized replacement for social capital in some cases.

The multidimensional clustering of health and its ecological risk factors

A diverse set of research has examined the ways in which population-level health and its ecological risk factors are embedded within self-reinforcing structures. Syndemic theory, for example, focuses on the co-occurrence of multiple diseases, whereas the spatial diffusion literature highlights the concentration of poor health among communities sharing geographic boundaries. This study combines these related but disciplinarily-isolated perspectives to examine the clustering of population-level health and its determinants across four dimensions: co-occurrence, spatial, temporal, and social network. Using data on U.S. county-level health outcomes and health factors from the Robert Wood Johnson Foundation's County Health Rankings, this study estimates associations between health outcomes within communities and the co-occurrence of community-level factors theorized to influence ecological health. Not only do health outcomes and their ecological risk factors cluster within counties, but also between geographically adjacent counties and counties connected via migration network pathways. Moreover, the self-reinforcing structures uncovered across the co-occurrence, spatial and network dimensions persist over time, and this clustering has consequences on county health and well-being. Rather than adopting the perspective that either health and its community-level factors should be broadly targeted and detached from local context or communities are different, have unique needs and thus should be treated in isolation, the approach advanced in this study identifies shared vulnerabilities in a way that allows for the development of knowledge networks between communities dealing with similar issues.

What Do Migrants Know About Their Childcare Rights? A First Exploration in West Germany

Although an increasing number of studies emphasise migrants’ lack of knowledge about their childcare rights as a crucial barrier to their childcare usage, almost none examines the conditions under which migrant families acquire this knowledge. This study contributes to the literature by exploring potential individual factors determining migrant families’ knowledge about their childcare rights in Germany. I use unique data collected through the project Migrants’ Welfare State Attitudes (MIFARE), in which nine different migrant groups in Germany were surveyed about their relation to the welfare state, including childcare. Analysing a total sample of 623 migrants living with children in their household and by using logistic regression analyses, I find that human and social capital play significant roles in explaining migrants’ knowledge about their childcare rights. Migrants who speak the host language sufficiently are more likely to know about their childcare rights; however, it does not matter whether migrants are lower or higher educated. Moreover, I observe that migrants benefit from their co-ethnic relations only if childcare usage is high among their ethnic group. Based on these results, policy recommendations are discussed in order to increase migrants’ knowledge about their childcare rights in Germany.

On the Motion of Substance in a Channel of a Network: Extended Model and New Classes of Probability Distributions

We discuss the motion of substance in a channel containing nodes of a network. Each node of the channel can exchange substance with: (i) neighboring nodes of the channel, (ii) network nodes which do not belong to the channel, and (iii) environment of the network. The new point in this study is that we assume possibility for exchange of substance among flows of substance between nodes of the channel and: (i) nodes that belong to the network but do not belong to the channel and (ii) environment of the network. This leads to an extension of the model of motion of substance and the extended model contains previous models as particular cases. We use a discrete-time model of motion of substance and consider a stationary regime of motion of substance in a channel containing a finite number of nodes. As results of the study, we obtain a class of probability distributions connected to the amount of substance in nodes of the channel. We prove that the obtained class of distributions contains all truncated discrete probability distributions of discrete random variable ω which can take values 0,1,⋯,N. Theory for the case of a channel containing infinite number of nodes is presented in Appendix A. The continuous version of the discussed discrete probability distributions is described in Appendix B. The discussed extended model and obtained results can be used for the study of phenomena that can be modeled by flows in networks: motion of resources, traffic flows, motion of migrants, etc.

Evacuees and Migrants Exhibit Different Migration Systems After the Great East Japan Earthquake and Tsunami

Research on the destinations of environmentally induced migrants has found simultaneous migration to both nearby and long-distance destinations, most likely caused by the comingling of evacuee and permanent migrant data. Using a unique data set of separate evacuee and migration destinations, we compare and contrast the pre-, peri-, and post-disaster migration systems of permanent migrants and temporary evacuees of the Great East Japan Earthquake and Tsunami. We construct and compare prefecture-to-prefecture migration matrices for Japanese prefectures to investigate the similarity of migration systems. We find evidence supporting the presence of two separate migration systems-one for evacuees, who seem to emphasize short distance migration, and one for more permanent migrants, who emphasize migration to destinations with preexisting ties. Additionally, our results show that permanent migration in the peri- and post-periods is largely identical to the preexisting migration system. Our results demonstrate stability in migration systems concerning migration after a major environmental event.

Statistical Characteristics of Stationary Flow of Substance in a Network Channel Containing Arbitrary Number of Arms

We study flow of substance in a channel of network which consists of nodes of network and edges which connect these nodes and form ways for motion of substance. The channel can have arbitrary number of arms and each arm can contain arbitrary number of nodes. The flow of substance is modeled by a system of ordinary differential equations. We discuss first a model for a channel which arms contain infinite number of nodes each. For stationary regime of motion of substance in such a channel we obtain probability distributions connected to distribution of substance in any of channel’s arms and in entire channel. Obtained distributions are not discussed by other authors and can be connected to Waring distribution. Next, we discuss a model for flow of substance in a channel which arms contain finite number of nodes each. We obtain probability distributions connected to distribution of substance in the nodes of the channel for stationary regime of flow of substance. These distributions are also new and we calculate corresponding information measure and Shannon information measure for studied kind of flow of substance.

El enfoque de sistemas migratorios revisitado. Una propuesta teórica para el estudio del sistema migratorio de América Latina y el Caribe

Resumen El objetivo de este artículo es revisitar los orígenes, desarrollo, límites y potencialidades del enfoque de sistemas migratorios, para formular una propuesta teórica que, a la hora de analizar la conformación, retroalimentación y reconfiguración de los sistemas migratorios, considere el papel de la estructura, de los factores de carácter meso (como las instituciones o los colectivos) y de la agencia migrante (individual y colectiva). Partimos para ello, de una perspectiva crítica dialéctica que establece un vínculo entre los elementos del sistema con los condicionantes estructurales, al tiempo que recupera la agencia migrante, principalmente en su dimensión colectiva. Nuestra propuesta será aplicada exploratoriamente al estudio del sistema migratorio de América Latina y el Caribe en el periodo 1970-2018. Más allá de una mera descripción de los principales rasgos del sistema y sus subsistemas, tratamos de mostrar los elementos que condicionan su estabilidad y evolución, resaltando, además de los elementos clásicos de los sistemas, el peso de los condicionantes estructurales, así como de las resistencias y estrategias desarrolladas por los colectivos migrantes.

Resituating relaunched migration systems as emergent entities manifested in geographic structures

While important and timely, the recent effort to 'relaunch' migration systems as emergent entities is premised on a mischaracterization and subsequent dismissal of decades of research showing that systems are ultimately expressed in geographic structures in the form of migration networks comprised of a set of places that are connected to one another by migration flows. In this paper, we reconcile this relaunch with past research on migration systems by considering whether and how changes in some of the actors and dynamics that create and sustain migration systems are expressed in corresponding changes in the geographic structure of migration flows. By elucidating these linkages, our work helps to strengthen the aforementioned relaunch of migration systems by ensuring greater continuity with prior research and, going forward, the continued utility of a migration systems perspective for diverse audiences and issues.

[Lifestyles and health status of migrants in a settlement of Barranquilla, Colombia, 2018]

OBJECTIVE

To describe the lifestyles and health status of returning Venezuelan and Colombian migrants in Villa Caracas, Barranquilla, in 2018.

METHODS

Descriptive, cross-sectional study with systematic sampling of dwellings. 229 people over 15 years of age from 90 homes were included.

RESULTS

Differences were found in the routes to arrive, commuting times and stay in the settlement between Venezuelan and returning Colombian migrants. Housing conditions and access to public services are limited: less than half of the dwellings have access to aqueduct, sewerage and bathrooms. In general, self-reported health status of migrants is very good or good and the prevalence of noncommunicable diseases was relatively low, with the exception of high blood pressure. Most of the people who consulted the emergency department reported effective access. Clinically significant depressive symptoms were found in 20% of the surveyed population.

CONCLUSIONS

The migrants of Villa Caracas are under high social vulnerability conditions given their economic and environmental conditions. Despite their lack of enrollment in the Colombian health system, they reported access to emergency care.

The Cross-country Determinants of Potential and Actual Migration

In this study, we use cross-country bilateral data to quantify a two-step process of international migration and its aggregate determinants. We first analyze which country-specific factors affect the probability that individuals join the pool of potential (aspiring) migrants. Then, we consider the bilateral and destination country factors that affect the frequency at which potential migrants turn into actual migrants. Using information on potential migrants from World Gallup surveys and on actual migrants from national censuses for 138 origin countries and 30 major destinations between 2000 and 2010, we analyze economic, policy, cultural, and network determinants of each step. We find that the size of the network of previous migrants and the average income per person at destination are crucial determinants of the size of the pool of potential migrants. Economic growth in the destination country, on the other hand, is the main economic generator of migration opportunities for a given pool of potential migrants. We also find that college-educated exhibit greater actual emigration rates mainly because of better chances in realizing their immigration potentials, rather than because of higher willingness to migrate.

Sin Coyote Ni Patrón: Why the “Migrant Network” Fails to Explain International Migration

The “migrant network” concept cannot explain large-scale international migratory flows. This article goes beyond a critique of its ahistorical and post factum nature. First, I argue that restrictions on its composition and functions also render the migrant network unable to explain why such migratory flows continue or expand even further. Second, a review of five studies illustrates why this concept, the propositions on which it rests, the methods it employs, and the conclusions that it imparts must be reconsidered. Third, the network analysis literature, along with my research data from the Mexico-U.S. case, suggest an alternative approach.

“International migration networks” include those from the labor-sending hometowns who are emphasized in migrant network studies, as well as a variety of other actors based in the militarized border zone and the labor-receiving regions. I conclude that accurate studies of migration must include the employers that demand new immigrant workers, as well as the labor smugglers and all other actors that respond to this demand. Immigration studies that fail to do so provide erroneous analyses which camouflage the activities of many network actors, and furnish an academic fig leaf behind which unintended, counterproductive, and even lethal public policies have been implemented.

By and large, the effective units of migration were (and are) neither individuals nor households but sets of people linked by acquaintance, kinship, and work experience who somehow incorporated American destinations into the mobility alternatives they considered when they reached critical decision points in their individual or collective lives (Tilly, 1990:84, emphasis added).

[Migrant n]etwork connections constitute a form of social capital that people can draw upon to gain access to foreign employment (Massey et al., 1993:448, emphasis added)

Conceptualizing International Labor Migration: A Structuration Perspective

This article applies the theory of structuration to international labor migration using case study material from the Philippines. It first provides a brief review of the functional and structural approaches to understanding labor migration and the theoretical impasse that has been created between them. It then reviews several attempts to resolve this impasse, including systems and networks approaches; these solutions are rejected on theoretical and empirical grounds. We suggest that migrant institutions may be a more appropriate mid-level concept than households or social networks to articulate various levels of analysis. We develop this concept in the context of the structuration theory of Anthony Giddens and attempt to apply this to the Philippines, concluding that this framework is eminently suited for further research on international labor migration.

Immigrant Incorporation in the Garment Industry of Los Angeles

Stressing the network's facilitation of immigrants’ searches for jobs and housing, migration network theory has conceptually overlooked the manner in which immigrants’ social networks also expand the supply of jobs and housing in target destinations by means of the ethnic economy. An expanded migration network theory takes into account the ethnic economy's role in creating new resources in the destination economy. However, the power of this objection wanes in the context of working-class immigrations that generate few entrepreneurs. Introduced here, the concept of immigrant economy responds to this contingency. Unlike ethnic economies, in which co-ethnics hire co-ethnics, immigrant economies arise when immigrants hire non-co-ethnic fellow immigrants. This situation usually arises when very entrepreneurial immigrant groups coexist in a labor market with working-class immigrant groups that generate few entrepreneurs of their own. Using evidence from the garment industry of Los Angeles, this paper estimates that only a third of immigrant employees found their jobs in a conventional ethnic economy. Half owed their employment to the immigrant economy in which, for the most part, Asian entrepreneurs employed Latino workers.

Thai Guestworker Export in Decline: The Rise and Fall of the Thailand-Taiwan Migration System

For decades, rural Thais have been employed as “guestworkers” in the Middle East and Asia. Once the predominate source of guest labor in Taiwan, Thais are being replaced by migrants from other countries. Building on the migration systems literature, we examine this transition. We find that Thais are increasingly deciding against work in Taiwan because of a diminishing wage gap between the two states. We argue that one outcome of the maturation of guestworker programs in Asia and the Middle East is the succession of migrant groups, especially a decline among those from relatively prosperous labor-sending states.

Emigration after socialist regime in Lithuania: why the West is still the best?

Purpose

The purpose of this paper is to review the emigration situation after the socialist regime and to reveal the main reasons for emigration in present-day Lithuania answering the question why “the West is still the best” remains important to modern Lithuania.

Design/methodology/approach

Statistical analysis of emigration during 1980-2015 in Lithuania was presented. Reasons for emigration were identified through a review of the scientific literature on emigration theories and push-pull factors. A questionnaire was prepared according to the proposed model to reveal the main reasons for Lithuanian emigration. In total, 1,586 migrants from Lithuania participated in the survey during October-November 2015.

Findings

The results revealed the main reasons for emigration according to push and pull factors related to economic issues, such as too low wages, differences between wages and income inequality, price policies and unemployment rates. However, non-economic reasons, particularly having relatives living abroad, influence the decision to migrate as well. A comparative analysis was made according to respondents’ occupation in the home country, their age and gender. In addition, it was found that emigration has become a community value and norm in Lithuania.

Research limitations/implications

The study was conducted over the internet. Therefore, only people using the internet participated in this study. Moreover, it is noted that only 21 percent of the respondents were male.

Practical implications

Based on migration theories, a list of push and pull migration reasons were identified. The findings present the main reasons for migration, which are based not only on statistical data, but also on survey responses in the case of Lithuania. Differences among demographic groups of respondents according to their occupation, gender and age were highlighted and targeted solutions could be applied in practice. Potential measures for decreasing emigration could also be designed based on these findings.

Social implications

Migration was proposed as a community value and norm in Lithuania.

Originality/value

Based on the migration theories and a questionnaire survey, the paper discusses reasons for emigration after the end of the socialist regime in Lithuania concentrating on the main reasons for emigration in contemporary Lithuania. In addition, it offers insights into demographic differences in reasons for emigration in relation to occupation, age and gender.

Recovery Migration After Hurricanes Katrina and Rita: Spatial Concentration and Intensification in the Migration System

Changes in the human migration systems of the Gulf of Mexico coastline counties affected by Hurricanes Katrina and Rita provide an example of how climate change may affect coastal populations. Crude climate change models predict a mass migration of "climate refugees," but an emerging literature on environmental migration suggests that most migration will be short-distance and short-duration within existing migration systems, with implications for the population recovery of disaster-stricken places. In this research, we derive a series of hypotheses on recovery migration predicting how the migration system of hurricane-affected coastline counties in the Gulf of Mexico was likely to have changed between the pre-disaster and the recovery periods. We test these hypotheses using data from the Internal Revenue Service on annual county-level migration flows, comparing the recovery period migration system (2007-2009) with the pre-disaster period (1999-2004). By observing county-to-county ties and flows, we find that recovery migration was strong: the migration system of the disaster-affected coastline counties became more spatially concentrated, while flows within it intensified and became more urbanized. Our analysis demonstrates how migration systems are likely to be affected by the more intense and frequent storms anticipated by climate change scenarios, with implications for the population recovery of disaster-affected places.

International Migration Decision-Making and Destination Selection Among Skilled Migrants

This research explored how skilled, self-selected migrants make a decision to leave their country of origin and choose a destination. Data were gathered through semi-structured interviews with 20 pre-departure and 26 post-arrival migrants to New Zealand from the United Kingdom/Ireland, India and South Africa. A thematic analysis was conducted separately for each country's data. For these migrants, the decision process contained three major decisions: whether, where and when to go. Regarding the question of whether to go, key factors were both intrapersonal and social. New Zealand was selected as a destination of choice due to quality of life, safety, environment, cultural similarity, job opportunities and the perception that migrants were wanted. On the question of when to go, the decision process was a negotiation between partners, and often extended family, which occurred over a long period of time.

Migration systems in Europe: evidence from harmonized flow data

Empirical tests of migration systems theory require consistent and complete data on international migration flows. Publicly available data, however, represent an inconsistent and incomplete set of measurements obtained from a variety of national data collection systems. We overcome these obstacles by standardizing the available migration reports of sending and receiving countries in the European Union and Norway each year from 2003-2007 and by estimating the remaining missing flows. The resulting harmonized estimates are then used to test migration systems theory. First, locating thresholds in the size of flows over time, we identify three migration systems within the European Union and Norway. Second, examining the key determinants of flows with respect to the predictions of migration systems theory, our results highlight the importance of shared experiences of nation-state formation, geography, and accession status in the European Union. Our findings lend support to migration systems theory and demonstrate that knowledge of migration systems may improve the accuracy of migration forecasts toward managing the impacts of migration as a source of social change in Europe.

The changing patterns of physician migration from Zimbabwe since 1990

Purpose

The paper seeks to investigate the leading causes of physician migration from Zimbabwe and to highlight the patterns of physician migration over the past‐two decades.

Design/methodology/approach

A mixed methods approach, involving a survey and interviews, was used to collect data for the study.

Findings

The paper demonstrates that personal networks, not recruitment agencies, are the main drivers of physician migration from the country. However, the importance of recruitment agencies as channels of information about job opportunities abroad has grown substantially over the last decade. The research findings suggest that Zimbabwe will continue losing physicians to other countries until economic and political stability has been restored in the country.

Originality/value

By highlighting the patterns and causes of physician migration from Zimbabwe, the paper makes a contribution to the implementation of policy measures aimed at retaining physicians in the country.

Linking migration, mobility and HIV

Population mobility is commonly identified as a key driver of the HIV epidemic, both linking geographically separate epidemics and intensifying transmission through inducing riskier sexual behaviours. However, beyond the well-known case studies of South African miners and East African truck drivers, the evidence on the links between HIV and mobility is nuanced, contradictory and inconclusive and is in part attributed to the abstract definitions of mobility used in different studies. This problematic conception of mobility, with no reference to who moves, their motivations for moving, or the characteristics of sending and receiving areas, can have a dramatic impact on how one understands the influence which this structural factor has on HIV risk in different settings. Future research on mobility and HIV transmission must incorporate an understanding of migration and mobility as dynamic processes and link different patterns and forms of mobility with location-specific sexual networks and HIV epidemiology.

L’aide transnationale au sein des familles d’immigrés qualifiés établis en Australie: une comparaison entre les immigrés italiens et les réfugiés afghans1

Pour la plupart, les relations d’aide intergénérationnelle transnationale ont été centrées sur la prise en nourrice et la garde d’enfants. En revanche, le présent article s’intéresse à l’échange d’aide transnationale entre des immigrés établis en Australie et leurs parents vieillissants « restés au pays », ce qui est en contradiction avec l’idée que l’aide ne peut s’opérer que dans un contexte de proximité physique. Le modèle d’aide transnationale de Baldassar, Baldock et Wilding (2007) est appliqué à deux groupes de familles récemment immigrées en Australie: des immigrés italiens qualifiés et des réfugiés humanitaires afghans, dont plusieurs sont aussi des cols blancs. Bien que les deux groupes d’immigrés soient arrivés en Australie depuis 1980, munis de diplômes professionnels, leurs familles diffèrent sensiblement pour ce qui est de leur capacité, leur obligation et leurs engagements à échanger de l’aide à distance. Dans ce contexte, le moment de l’arrivée et les qualifications professionnelles sont moins pertinents que les autres facteurs qui nuisent aux pratiques et procédés d’aide transnationale. Parmi les facteurs particulièrement importants, notons les conditions économiques et sociales des familles dans le pays d’origine; les trajectoires d’établissement et d’intégration des immigrés dans leur pays d’accueil ainsi que la disponibilité des services de bien-être et des infrastructures de communications dans chaque pays.

Branch migration and the international dispersal of families

This paper discusses the dispersal of facilities where family members migrate to different destination countries. Terminology for internationally dispersed families is proposed, and the term branch migration is suggested for the migration of related people from the same source country to different destination countries. Data from two 1993 surveys of senior secondary students show that 22% of Sydney students and 20% of Hong Kong students have relatives in two or more other countries. The data suggest that many Asian migrant families have branched between the US, Canada, Australia and other migrant-receiving nations.

Information, communication and networks in international migration systems

"This paper focuses on the role of information and communication in international migration by means of a survey which covers economic and broader perspectives, both at the micro and macro levels. The human capital model of migration is reviewed and the likely impact of recent and anticipated developments in telecommunications technology is noted. The job search model is reformulated in the context of international migration but extensive modification is required to describe the potential sampling of job offers and other informational needs of international migrants. It is argued that spatial selectivity is to a large extent influenced by migration networks in which information flows play a critical role. This is further elucidated by offering an analytical framework based on the systems approach to migration."

Now flows of new settlers come predominantly from Asia and the Pacific....This paper is about return migration--a process that has been largely ignored in the literature on international migration to New Zealand."
