Migration stock and the issue of competing and complementary flows in United States interstate migration

The purpose of this paper is to study the determinants of interstate migration in the United States from 1965–1970 when a new change in direction of migration has started, and to examine the flow creation or flow diversion that results from migration to some appealing regions. Several related variables have been selected and tested for gross interstate migration flows. The results show that overall both push and pull factors have not been important. People from higher income regions migrate more, and migrants tend to move to states with higher incomes and larger population. Distance was not found to act as a significant deterrence to migration, whereas population density of origin and destination was significant. Previous migration was found to have a very strong effect on migration. The results of the study also suggested that there has been a major change in the location of growth areas in the United States during 1955–1970.The study of concurrent flow showed that the states of Texas, Louisiana, Mississippi, Alabama, Georgia, and Florida combined have positively influenced migratory flow between origin and destination states. Empirical results, however, also showed that California did not have flow creation or flow diversion effects on interstate migration.This research was supported partly through Organized Research Funds of The University of Texas at Arlington.     

Exploring Child Mortality Risks Associated with Diverse Patterns of Maternal Migration in Haiti

Internal migration is a salient dimension of adulthood in Haiti, particularly among women. Despite the high prevalence of migration in Haiti, it remains unknown whether Haitian women’s diverse patterns of migration influence their children’s health and survival. In this paper, we introduce the concept of lateral (i.e., rural-to-rural, urban-to-urban) versus nonlateral (i.e., rural-to-urban, urban-to-rural) migration to describe how some patterns of mothers’ internal migration may be associated with particularly high mortality among children. We use the 2006 Haitian Demographic and Health Survey to estimate a series of discrete-time hazard models among 7,409 rural children and 3,864 urban children. We find that compared with their peers with nonmigrant mothers, children born to lateral migrants generally experience lower mortality, whereas those born to nonlateral migrants generally experience higher mortality. Although there are important distinctions across Haiti’s rural and urban contexts, these associations remain net of socioeconomic factors, suggesting they are not entirely attributable to migrant selection. Considering the timing of maternal migration uncovers even more variation in the child health implications of maternal migration; however, the results counter the standard disruption and adaptation perspective. Although future work is needed to identify the processes underlying the differential risk of child mortality across lateral versus nonlateral migrants, the study demonstrates that looking beyond rural-to-urban migration and considering the timing of maternal migration can provide a fuller, more complex understanding of migration’s association with child health.     

Earnings adjustment of temporary migrants

The strong incentives of migrants to invest into human capital and the positive selective character of migration are the main explanations for the rapid decrease of the earnings gap between migrants and natives, and, in some cases, the cross-over of migrants' earings profiles with those of native workers, as found in a variety of empirical studies on migration to the USA, Canada and Australia. The present paper shows that in the case of temporary migration the optimal investment into country specific human capital should be lower than in the case of permanent migration. Investments may not be sufficient to allow migrants' earnings to catch up with those of native workers. Furthermore, it is shown that migration is positively selective only under certain labor market conditions. Empirical findings support the hypothesis that the migrant's length of stay in the host country has an effect on his investment into human capital and, consequently, on his earnings position. The results strongly suggest the need for carefully differentiating between temporary and permanent migration when investigating migrants' learnings assimilation.I am grateful to Augustin Maravall, John Micklewright, Graham Mizon, Christoph M.

Climate change and population migration in Brazil’s Northeast: scenarios for 2025–2050

This research contributes to an understanding of the relationship between climate change, economic impacts and migration. We model the long-term relationship (up to 45 years of projection) between demographic dynamics—particularly migration—driven by changes in the performance of the economy due to climate changes in the Northeast region of Brazil. The region is of particular relevance to the study of climate change impacts given its large human population (28% of Brazil’s population) and high levels of impoverishment, having an extensive semi-dry area which will be severely impacted by growing temperatures. Ultimately, the integrated model generates state- and municipal-level migration scenarios based on climate change impacts on the primary economic sectors and their articulations with other sectors. Results suggest that the predicted climate changes will impact severely the agriculture sector in the region, acting as a potential migration push factor to other regions in the country. Finally, we discuss how the increased vulnerability of some groups, particularly migrants, can be factored into Brazilian public policy and planning.     

Relative deprivation and international migration oded stark

This article provides theoretical reasoning and empirical evidence that international migration decisions are influenced by relative as well as absolute income considerations. Potential gains in absolute income through migration are likely to play an important role in households' migration decisions, but international migration by household members who hold promise for success as labor migrants can also be an effective strategy to improve a household's income position relative to others in the household's reference group. The findings reported in this article provide empirical support for the hypothesis that relative deprivation plays a significant role in Mexico-to-U.S. migration decisions. The findings also suggest that this migration is an effective mechanism for achieving income gains in households that send migrants to the U.S. and that households wisely choose as migrants those of their members who are most likely to provide net income gains.     

Effects of migration on the educational levels of the black resident population at the origin and destination, 1955–1960 and 1965–1970

Using the 1960 and 1970 census data, this paper analyzes the net effects of the interregional migration of black males on the educational levels of the resident black male population at the regions of origin and destination. Significant variations are observed in the educational selectivity of out-migrants from each region, by region of destination. Comparing the educational levels of the return migrants to the South with those of the resident population in the nonsouthern regions provides no evidence that the return migrants are "failed" migrants. The net effect of interregional migration on the educational levels of the black male resident population at the regions of origin and destination is insignificant in most age groups, for both the 1955--1960 and 1965--1970 periods. In particular, in-migration from the South to nonsouthern regions has little effect on the educational levels of the resident population in most age groups. In fact, for nonsouthern regions, out-migration is more detrimental to the educational level of the resident black male population than is in-migration from the South. Furthermore, the net effect of interregional migration has declined from the 1955--1960 period to the 1965--1970 period.     

Migration as Development: Household Survey Evidence on Migrants’ Wage Gains

The study of the effects of migration on migrants themselves has not garnered nearly as much attention within the recent international migration literature as other topics, such as motives for migration, the effects of immigration on receiving countries, and the effects of emigration on countries of origin. Focusing instead on these effects on migrants themselves, an issue of primary importance to the discussion of international migration, I present novel data collected through household interviews in communities both in Mexico and the United States. Data gathered using an ethnosurvey approach, combining the techniques of ethnographic fieldwork with representative survey sampling in order to collect both quantitative and qualitative data, permit a careful comparison of absolute and relative wage gains for interviewees with data from existing Mexican surveys. Key findings include: (1) upon crossing the border, even given the cost of migration, migrants indeed stand to collect large net absolute gains, average incomes increasing more than fivefold immediately; (2) relative gains are large, many migrants moving from the lower deciles of origin wage distributions to the top deciles; and (3) average gains accruing to migrants surpass those of even the most successful current programs of economic development. In turn, these findings verify the importance of including consideration for the migrants themselves in any ongoing discussions of how to construct effective migration policy around the world.     

Networks Matter: Male Mexican Migrants’ Use of Hospitals

Using the behavioral model for health care use and unique data from the Mexican migration project, we explore the factors associated with hospital use among Mexican male migrants to the US. Twenty-eight percent of the respondents reported receiving healthcare from a hospital. In addition to established enabling factors of time in the US and English language ability, this research points to the importance of family social networks as enabling hospital health care use among migrants. Migrants with more ties to family members with migration experience have an increased likelihood of using emergency room healthcare. The research adds to the body of literature by providing evidence that ties to individuals with US migration experience increases migrants’ probability of accessing healthcare at hospitals.     

Interregional flows of economically active persons in France, 1975–1982

Recent net interregional migration into southern and western France is widely appreciated, but much less is known about the composition of these flows in terms of the occupational characteristics of economically active migrants. Using results from the 1982 census, this article disaggregates net flows to reveal inflows and outflows of migrants defined by gender and occupational groups. Important differences between these groups with regard to absolute flows and geographical mobility are uncovered and discussed in relation to the new spatial division of labor perspective on counterurbanization.     

The environment as a determinant of child mortality among migrants in frontier areas of Pará and RondÔnia, Brazil, 1980

This article examines child mortality as an indicator of the quality of life among migrants living in Brazilian Amazonia in 1980. I focus on migrants in the frontier states of Pará and RondÔnia, which experienced rapid settlement during the 1970s. The key question here is the effect of settlement location on child mortality rates. While RondÔnia had lower ratios of population per public health establishments and personnel than Pará, RondÔnia nonetheless exhibited a higher malaria prevalence in 1980. I therefore attribute locational differences in child mortality to environmental factors important to malaria transmission rather than to health care infrastructure. The findings from multivariate regression analysis show that net of the effects of human capital, migration history and migrant living standards, settling in Pará rather than RondÔnia resulted in significantly lower rates of child mortality. These findings suggest that environmental factors coinciding with location of frontier settlement had important consequences for the living standards of migrants in the Brazilian Amazon.     

The Consequences of Migration to the United States for Short-Term Changes in the Health of Mexican Immigrants

Although many studies have attempted to examine the consequences of Mexico-U.S. migration for Mexican immigrants’ health, few have had adequate data to generate the appropriate comparisons. In this article, we use data from two waves of the Mexican Family Life Survey (MxFLS) to compare the health of current migrants from Mexico with those of earlier migrants and nonmigrants. Because the longitudinal data permit us to examine short-term changes in health status subsequent to the baseline survey for current migrants and for Mexican residents, as well as to control for the potential health selectivity of migrants, the results provide a clearer picture of the consequences of immigration for Mexican migrant health than have previous studies. Our findings demonstrate that current migrants are more likely to experience recent changes in health status—both improvements and declines—than either earlier migrants or nonmigrants. The net effect, however, is a decline in health for current migrants: compared with never migrants, the health of current migrants is much more likely to have declined in the year or two since migration and not significantly more likely to have improved. Thus, it appears that the migration process itself and/or the experiences of the immediate post-migration period detrimentally affect Mexican immigrants’ health.

Female Migration and Child Occupation in Rural El Salvador

This article looks at the consequences of migration in terms of child education and child labor using a unique rural panel dataset for El Salvador. Results suggest gender differences in the consequences of migration on child activities that remain in El Salvador. While female migration tends to reduce child labor, both in domestic and non-domestic activities, male migration seems to stimulate it, in particular in terms of domestic labor. In contrast, while male migration has null or slightly positive impact in terms of school enrollment rates, female migration apparently reduces the likelihood that a particular child stays at school. Some of these results differ according to the gender of the child. The results do not seem to be driven by female migrants remitting more than males, but rather to alternative competing explanations, such as the existence of child–adult male labor substitution, differences in the use of remittances by gender of the recipient person, or limited ability to monitor funds when remitted by female migrants.     

The politics of leisure and labor mobilities: discourses of tourism and transnational migration in Central Java,Indonesia

This article presents narratives and tropes of transnational tourism from a less considered perspective: rural migrant-origin villagers of Central Java. Drawing from ethnographic fieldwork conducted in Cilacap and Yogyakarta, I analyze how and why some former temporary labor migrants depict their typically harsh experiences in terms of tourism and leisure. Addressing the tendency in current research to approach labor migration and tourism as mutually exclusive or unrelated class categories and experiences, I consider the ways in which former migrants and non-migrant villagers evaluate or identify labor migration in terms of gender, class, religious, and ethno-national subjectivities associated with ‘tourist’ and/or ‘migrant’ categories. Popular and commercial imaginations of leisure travel and tourism importantly shape the subjectivities and positionalities of precarious labor migrants. Foregrounding the relations between tourism and labor migration reveals the multi-scalar ways in which associated discourses and infrastructures of both mutually shape and constitute global socio-economic inequalities.     

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。     

进城还是回村？——跨省婚迁者的空间选择

在经济社会转型、人口频繁流动的条件下,婚迁由乡到城的单向迁移转变成为城乡互动的双向流动。婚迁者留在城市还是回到乡村,要取决于多种条件。本研究通过测度跨省婚迁的性别比发现,自1990年来的20年间我国省际婚迁性别比下降近一半。全国省际婚迁性别比呈现城市-城镇-乡村两端大中间小的“微笑曲线”。在婚迁的空间选择上,男性以城市为主,女性则以乡村为主。进一步分析影响婚姻迁移的因素发现,经济变量中人均GDP对总婚迁和城市婚迁呈正向影响,城镇和乡村呈负向影响;居民收入和消费状况对婚姻迁移产生正向影响,但消费的城乡差别则对其产生负向影响;人口的城乡流动与迁移以及社会变量中各因素对跨省婚迁产生正向影响,而文化变量中的各因素则形成负向影响。     

Multiple Migration Flows of Romanians

Abstract

Most studies on international migration examine population movement between a country of origin and a destination. This article aims to show that migrants often change destinations, a less studied pattern of ‘multiple migrations’. This article explores how such migration occurs and analyses the variables accounting for it. Drawing on qualitative fieldwork research amongst Romanian migrants in Portugal, the article concludes that the growth in multiple migrations of Romanian migrants throughout Europe can be explained by a combination of migration policies and social networks, mediated by migrants’ level of education and type of occupation at the destination.     

Migration and Health Selectivity in the Context of Internal Migration in China, 1997–2009

Using data from the 1997?C2009 waves of the China Health and Nutrition Survey, we examine the ??healthy migrant hypothesis?? in a setting where internal migrants face significant barriers to movement. Going beyond much of the existing literature in the Chinese context, we use an appropriate comparison between migrants and non-migrants at origin, using detailed health measures, and data spanning a wider geographic and temporal extent than had been previously considered. Consistent with research from both international migration contexts and other internal migration settings, we find that migrants are positively selected on the basis of health, although the relationship between health and migration diminishes across time. The strongest evidence for health selection comes from a subjective self-reported health measure, although we also find evidence for selection against those experiencing acute health conditions. We speculate that the across-time differentiation may be caused by the rapid social, economic and policy changes in China??s economic reform era. Thus, we suggest that migration scholars should consider the changing macro context when theorizing about selection factors.     

Rethinking measures of migration: On the decomposition of net migration

The purpose of this paper is to “resurrect” the measure of net migration and defend its continued use under specific research circumstances, despite the current dissatisfaction with the measure as expressed by some scholars. We employ data from the 1980 Census of Population to compare five measures of migration, including net migration rates, in- and out-migration rates, migration efficiency ratios and migration turnover rates. We demonstrate the additivity of in- and out-migration rates with net migration rates and migration turnover rates. Also, we show how the migration efficiency ratio and turnover rates are conceptually and mathematically related. Finally, a simple multivariate model is estimated to show how regression coefficients from in-and out-migration rate models are related to net migration and migration turnover rates.
