Death at the Border: Efficacy and Unintended Consequences of US Immigration Control Policy

This article assesses the efficacy of the strategy of immigration control implemented by the US government since 1993 in reducing illegal entry attempts, and documents some of the unintended consequences of this strategy, especially a sharp increase in mortality among unauthorized migrants along certain segments of the Mexico–US border. The available data suggest that the current strategy of border enforcement has resulted in rechanneling flows of unauthorized migrants to more hazardous areas, raising fees charged by people‐smugglers, and discouraging unauthorized migrants already in the US from returning to their places of origin. However, there is no evidence that the strategy is deterring or preventing significant numbers of new illegal entries, particularly given the absence of a serious effort to curtail employment of unauthorized migrants through worksite enforcement. An expanded temporary worker program, selective legalization of unauthorized Mexican workers residing in the United States, and other proposals under consideration by the US and Mexican governments are unlikely to reduce migrant deaths resulting from the current strategy of border enforcement.     

Shifts in the employment outcomes among Mexican migrants to the United States, 1976–2009

Although studies have examined the impact of U.S. immigration policy shifts in the 1980s and 1990s on the employment outcomes of migrants, scholars have paid less attention to how the federal government's shifting approach to worksite enforcement has transformed the conditions in which Mexican migrants work. Consistent with previous research, we find a worsening of conditions for both unauthorized and legal Mexican migrants in the years following the passage of the Immigration Reform and Control Act (IRCA) and that unauthorized status is associated with more unfavorable workplace conditions relative to legal immigrants. However, in the first decade of the 21st century, we also find that unauthorized immigrants’ employment outcomes more closely resemble those of legal immigrants now than in the past, suggesting a dramatic shift in the ways that employers treat unauthorized immigrants on the job. This convergence between authorized and unauthorized migrants is consistent with federal policies and practices related to workplace enforcement.     

The new labor market: Immigrants and wages after IRCA

We examine the effect of the Immigration Reform and Control Act (IRCA) on migrants' wages using data gathered in 39 Mexican communities and their U.S. destination areas. We examine changes in the determinants of wages before and after the passage of IRCA, as well as the effects of its massive legalization program. Migrants' wages deteriorated steadily between 1970 and 1995, but IRCA did not foment discrimination against Mexican workers per se. Rather, it appears to have encouraged greater discrimination against undocumented migrants, with employers passing the costs and risks of unauthorized hiring on to the workers. Although available data do not permit us to eliminate competing explanations entirely, limited controls suggest that the post-IRCA wage penalty against undocumented migrants did not stem from an expansion of the immigrant labor supply, an increase in the use of labor subcontracting, or a deterioration of the U.S. labor market.     

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.     

The Migrant Border Crossing Study: A methodological overview of research along the Sonora–Arizona border

Increased border enforcement efforts have redistributed unauthorized Mexican migration to the United States (US) away from traditional points of crossing, such as San Diego and El Paso, and into more remote areas along the US–Mexico border, including southern Arizona. Yet relatively little quantitative scholarly work exists examining Mexican migrants’ crossing, apprehension, and repatriation experiences in southern Arizona. We contend that if scholars truly want to understand the experiences of unauthorized migrants in transit, such migrants should be interviewed either at the border after being removed from the US, or during their trajectories across the border, or both. This paper provides a methodological overview of the Migrant Border Crossing Study (MBCS), a unique data source on Mexican migrants who attempted an unauthorized crossing along the Sonora–Arizona border, were apprehended, and repatriated to Nogales, Sonora in 2007–09. We also discuss substantive and theoretical contributions of the MBCS.     

How Do Tougher Immigration Measures Affect Unauthorized Immigrants?

The recent impetus of tougher immigration-related measures passed at the state level raises concerns about the impact of such measures on the migration experience, trajectory, and future plans of unauthorized immigrants. In a recent and unique survey of Mexican unauthorized immigrants interviewed upon their voluntary return or deportation to Mexico, almost a third reported experiencing difficulties in obtaining social or government services, finding legal assistance, or obtaining health care services. Additionally, half of these unauthorized immigrants reported fearing deportation. When we assess how the enactment of punitive measures against unauthorized immigrants, such as E-Verify mandates, has affected their migration experience, we find no evidence of a statistically significant association between these measures and the difficulties reported by unauthorized immigrants in accessing a variety of services. However, the enactment of these mandates infuses deportation fear, reduces interstate mobility among voluntary returnees during their last migration spell, and helps curb deportees’ intent to return to the United States in the near future.     

Measuring Geographic Migration Patterns Using <Emphasis Type="Italic">Matrículas Consulares</Emphasis>

In this article, we show how to use administrative data from the Matrícula Consular de Alta Seguridad (MCAS) identification card program to measure the joint distribution of sending and receiving locations for migrants from Mexico to the United States. Whereas other data sources cover only a small fraction of source or destination locations or include only very coarse geographic information, the MCAS data provide complete geographic coverage of both countries, detailed information on migrants’ sources and destinations, and a very large sample size. We first confirm the quality and representativeness of the MCAS data by comparing them with well-known household surveys in Mexico and the United States, finding strong agreement on the migrant location distributions available across data sets. We then document substantial differences in the mix of destinations for migrants from different places within the same source state, demonstrating the importance of detailed substate geographical information. We conclude with an example of how these detailed data can be used to study the effects of destination-specific conditions on migration patterns. We find that an Arizona law reducing employment opportunities for unauthorized migrants decreased emigration from and increased return migration to Mexican source regions with strong initial ties to Arizona.     

Two Decades of Negative Educational Selectivity of Mexican Migrants to the United States

Immigration is commonly considered to be selective of more educated individuals. Previous US studies comparing the educational attainment of Mexican immigrants in the United States to that of the Mexican resident population support this characterization. Upward educational‐attainment biases in both coverage and measurement, however, may be substantial in US data sources. Moreover, differences in educational attainment by place size are very large within Mexico, and US data sources provide no information on immigrants' places of origin within Mexico. To address these problems, we use multiple sources of nationally representative Mexican survey data to re‐evaluate the educational selectivity of working‐age Mexican migrants to the United States over the 1990s and 2000s. We document disproportionately rural and small‐urban‐area origins of Mexican migrants and a steep positive gradient of educational attainment by place size. We show that together these conditions induced strongly negative educational selection of Mexican migrants throughout the 1990s and 2000s. We interpret this finding as consistent with low returns to education among unauthorized migrants and few opportunities for authorized migration.     

Changing conditions in the US labor market

In this paper, we assess the extent to which the Immigration Reform and Control Act (IRCA) of 1986 affected US labor market conditions facing Mexican migrant workers. Using data gathered from migrants in ten Mexican communities, as well as out-migrants from those communities located in the USA, we examined whether and how IRCA affected US wages, hours worked, and the terms of employment. Estimated period effects did not indicate a clear break in most of these variables following IRCA's passage in 1986, except for hours worked and monthly income. Our analyses did reveal a fairly consistent pattern of deterioration in the labor market conditions facing undocumented migrants, however. Compared to illegal migrants working in the USA before IRCA, those migrating afterward worked fewer hours and were less likely to have taxes withheld from their pay. We also found evidence that undocumented migrants were pushed from the agrarian to the urban economy by the increase in labor supply occasioned by the SAW program.     

Mexican Migration to the United States Pacific Northwest

The migration of Mexicans to the Pacific Northwest region(PNW) of the United States has received little attention in scholarly literature. This is unfortunate, as Mexican migration has significantly affected this region, both economically and culturally. Using data supplied by the Mexican Migration Project, we compare the characteristics of Mexican migrantsto the Pacific Northwest with characteristics of Mexicans who migrate to other parts of the U.S. The data reveal significant differences between the two groups: Mexican migrants to the PNW earn lower U.S. wages, are less likely to migrate illegally, and more commonly work in agriculture. They also are more transitory in nature, making more frequent, shorter trips to the U.S. Most interesting is that PNW migrants send significantly more money back home compared to Mexican migrants in other parts of the U.S., even after controlling for the aforementioned differences in individual characteristics.     

Social bonding and loneliness after network disruption: A longitudinal study of East German refugees

After the 1989 breakdown of the communist system, 235 East Germans were interviewed three times during the two years following their transition to West Berlin. In moving to the west, the migrants had to deal with various stressors, among them the lack of social ties in their new environment. Fortunately, the number of their new friends increased steadily, and loneliness declined. These changes, however, differed between sexes and age groups. Men made more friends than women, in particular same-sex friends, whereas women knitted ties with both sexes. The young built larger networks than the intermediate age group. Loneliness emerged as an inhibiting factor in the bonding process. The study demonstrates how well these refugees coped with a social crisis. It also examines the roles that loneliness and social bonding played in the readjustment process.     

Mexico–US Migration: Views from Both Sides of the Border

Migration to the United States increased sharply in the 1980s and 1990s, raising political concerns. The immigrant flow from Mexico, both authorized and unauthorized, was particularly large. Good data would con‐tribute to rational discussion of this politically charged issue, but data on immigration, particularly of the unauthorized, are notoriously poor. This article applies residual estimation techniques to data from the 1990 and 2000 population censuses of Mexico and the United States (Mexico‐born population) to quantify the intercensal migration flow, arguing that the reasons why unauthorized migrants might avoid enumeration in the United States would not adversely affect data from Mexico. Results suggest that the annual net flow of migrants aged 10 to 80 years from Mexico to the United States averaged between 324,000 and 440,000 between 1990 and 2000. A sensitivity analysis indicates that these results are quite robust (especially those using US data) to likely errors.     

Can indigenous transborder migrants affect environmental governance in their communities of origin? Evidence from Mexico

Despite high rates of out-migration, Mexican indigenous communities play a crucial role in biodiversity conservation. However, little is known about migrants’ role in environmental management. This research brief explores the case of the Purépecha of San Pedro Ocumicho, Michoacán, and its transborder community in the Coachella Valley of California. We find that migrants maintain strong cultural ties to their community of origin. However, many are undocumented, are unable to access steady and well-paid employment, and would be unable to return to California were they to visit Mexico. Furthermore, government structures in Ocumicho are weak, providing few opportunities for migrants to contribute. These factors currently preclude migrants from influencing environmental decision making in their home community. Our findings point to the need for more comprehensive and longitudinal studies to better document and explain the variations in migrant support for environmental governance in their communities of origin.     

Gender, Job Searching, and Employment Outcomes among Mexican Immigrants

Past quantitative research has typically disregarded the effect of gender on the relationship between social capital and immigrant adaptation. However, recent theory and qualitative evidence suggest that gender is a significant factor moderating this association. I use Mexican Migration Project (MMP) data regarding Mexican immigrant experiences in the U.S. to examine quantitatively how the process of job searching, and the effects of network-based job searching, vary by gender. Results show no evidence of overall sex differences in the likelihood of using network (i.e., family-based or friend-based) or individual (i.e., non-network) job search methods, but there are sex differences in the processes affecting job search method used. Settlement increases women’s use of their friend networks to obtain work, while for men, it decreases the use of networks of any kind. Contrary to conventional wisdom, women who use network-based job searches are less likely to obtain formal sector employment than women who find work without network assistance. Conversely, using network-based job searches increases the likelihood that men will find work in the formal sector. Since employment in the formal sector is correlated with wages, as well as nonwage benefits, this suggests that using networks in the job search has markedly different effects on the overall economic well-being of male and female Mexican immigrants in the U.S.     

Engendering migrant networks: The case of Mexican migration

This article compares the impact of family migrant and destination-specific networks on international and internal migration. We find that migrant networks are more important for international moves than for internal moves and that female networks are more important than male networks for moves within Mexico. For moves to the United States, male migrant networks are more important for prospective male migrants than for female migrants, and female migrant networks lower the odds of male migration, but significantly increase female migration. We suggest that distinguishing the gender composition and destination content of migrant networks deepens our understanding of how cumulative causation affects patterns of Mexican migration.     

A demonstration of the effect of seasonal migration on fertility

Fertility estimates were calculated using own children data from the Mexican migrant town of Guadalupe, Michoacan. In this town, 75 percent of families have a member working in the United States, and wives are often regularly separated from their migrant husbands. Simulations by Menken (1979) and Bongaarts and Potter (1979) suggest that fertility among these women should be depressed. Our results confirmed this hypothesis, showing that the seasonal absence of migrant husbands disrupted both the level and timing of fertility. However, the effect was greater for legal than for illegal migrants, a pattern that stemmed from social factors as well as physical separation. A logistic regression analysis showed that reductions in birth probabilities are greater the longer a couple is separated, and that these reductions are in the range expected from prior simulations.     

Types of Personal Social Networks of Older Adults in Portugal

This study presents and discusses a three-dimensional typology for personal social networks of Portuguese older adults. We used a K-means cluster analysis of structural, functional and relational-contextual variables of the networks of 612 participants aged 65?+?(M?=?76?±?7.6), mostly women (63%). Four types of networks emerged: family networks, friendship networks, neighbourhood networks and institutional networks. The most frequent are family networks (61.8%), constituted by 94.6% of family ties, on average, attesting the familistic nature of the older persons’ networks in Portugal, followed by friendship networks (23.5%) and neighbourhood networks (11.9%). The less frequent type is the institutional network (2.8%), dominated by formal ties (M?=?59.3%). Sociographic profiles reveal that family networks are more likely to be held by middle-old focal subjects, married or widowed, and with children. Friendship and neighbourhood networks are held by young-old subjects with different marital status, many of them living alone, with a higher proportion of men with friendship networks. Institutional networks are held by old–old, widowed or single with no children. The presented typology contributes to understand social support needs and social isolation. The conclusions allow to anticipate social services’ demand trajectories and to propose intervention plans and social policy measures to promote the wellbeing of the older population.

     

How Job Characteristics Affect International Migration: The Role of Informality in Mexico

Despite the importance given to employment opportunities as a primary motive for migration, previous studies have paid insufficient attention to the kinds of jobs that are more likely to retain workers in their countries of origin. We use information from a panel survey of Mexican adults to examine how job characteristics affect the risk of international migration. The sampling strategy and overall size of the survey allow us to analyze the effect of employment characteristics on migration from urban areas, which have much greater labor market diversity, and to separate our analysis by gender. We also distinguish migrants according to whether they migrate for work or for other reasons. We find informality to be a significant predictor of international migration. Even after controlling for individual factors including workers’ wages, as well as various household- and community-level predictors, we find that workers employed in the informal sector have significantly higher odds of migrating than their counterparts in the formal sector. The pervasive nature of informality in many developing countries from which a high proportion of international migrants originate may therefore create a constant supply of workers who are predisposed to migrate. Our findings thus have important implications for a proper understanding of the effects of economic development on migration.     

Status Homophily,Sexual Identity,and Lesbian Social Ties

The literature on friendship and social networks finds that individuals form social ties with people who are like them—a much studied concept called homophily. However, few studies have explicitly examined sexual identity as a point of homophily. Scholars from multiple disciplines have long argued that sexuality influences the organization of our social worlds, yet most studies of friendship and social networks under-examine or overlook the influence of sexual identity. This study addresses that gap by looking at status homophily among lesbian social ties to examine the influence of sexual identity, as well as gender, race, class, and family, on their personal networks. Using survey data from 544 U.S. lesbian respondents, the findings make visible some of the factors and forces that shape social ties for lesbians. The results point to the importance of sexuality as an organizing element of social life, and suggest that studies that examine social networks or friendships more often make sexual identity, gender, and intersecting social locations a central focus.     

Intra-household conflicts in migration decisionmaking: return and pendulum migration in Morocco

By analyzing the migration behavior and transnational residential strategies of first-generation, aging migrants from a particular Moroccan sending region, this study contributes to a conceptual critique of migration theories that identify the household as the most relevant decisionmaking unit. It highlights the role of intra-household power inequalities and conflicts in migration decisionmaking as well as the effects of migration decisions for intra-household power relations. Many labor migrants who left Morocco to work in Europe in the 1960s and 1970s did not realize their wish to return but instead ended up reunifying their families at the destination. An increasing proportion adopts a pendulum migration strategy to reconcile their own wish to retain strong ties with Morocco with the reluctance of children and spouses to return. Migrants who unilaterally decided not to reunify their families usually return after their active working life. However, this unilateral decision also blocks legal entry into Europe for their children, which has generated considerable intergenerational tensions.
