Unauthorized Mexican workers in the 1990 Los Angeles County labour force

By analysing how unauthorized Mexicans compare with seven other ethno'racial groups in Los Angeles County, separately and collectively, by educational attainment and time spent in the US, we find that unauthorized Mexicans had relatively fewer years of formal education (either in the US or in Mexico) and had been in the US a relatively fewer number of years than in-migrants of other ethno-racial backgrounds in 1990. These findings are then used as proxies to compare the human capital endowments of different ethno-racial groups. We next estimate the number of unauthorized Mexicans by occupation, industry and class of workers, and compare these distributions with the total labour force and with the other ethno-racial groups in Los Angeles County. To the extent that unauthorized Mexicans are found to be substitutes (complements) in the labour market, they can be expected to be a valid (invalid) empirical source of social tension and hence contemporary restrictionist immigration policy sentiment. Results show that amounts of human capital are positively related to the kinds of occupations filled. Analysis of the percentage of discordant pairs shows that unauthorized Mexicans are found to be most dissimilar (potential complements) to non-Latino (1) Anglos; (2) Blacks; (3) American Indians, Aleuts, and Eskimos; and (4) Asians and Pacific Islanders. Results also show that those ethno-racial groups most similar to (potential substitutes for) unauthorized Mexicans are (1) legal Mexican in-migrants and (2) other Latino foreign-born persons (both authorized and unauthorized). The ethno-racial group which falls into the intermediate realm of (dis)similarity is US-born Mexican. Consequently, for most persons residing in Los Angeles County the rise of restrictionist immigrant sentiment is not consistent with their labour market experiences, and restrictionist immigration policy, to the extent it is based on a labour market competition assumptions, may not be justified.     

Patterns of economic cooperation among Israeli immigrants in Los Angeles

"This article examines economic activities developed among Israeli immigrants in Los Angeles. Previous studies have asserted that little cooperation exists among Israelis in the United States. However, our findings, based on participant observation and in-depth interviews, suggest that Israelis are involved in a host of collective social and economic endeavors.... Forms of cooperation among two...groups, Kibbutzniks and Persian-origin Israelis, are discussed here. Israeli immigrants' use of ethnic labor markets [is] explored, as well as the nature of co-ethnic cooperation in various industries. Conclusions suggest that Israeli immigrant cooperation is a complex matter, shaped by national loyalties, subgroup ties and the larger social and economic contexts in which they function."     

Social Capital is Associated with Earnings among Foreign‐born Mexican Men but not Women in Los Angeles County

The mechanisms through which social capital is accumulated may influence its relationship with hourly earnings. Because Mexican men and women accumulate social capital differently, for instance, gender may be an important factor for understanding social capital’s association with Mexican migrant earnings. Unlike past research that often fails to differentiate between various social capital metrics (e.g., social network member reciprocity, participation in civic group organizations, neighbourhood trust), this article estimates two of these associations with wages while controlling for individual‐, household‐ and neighbourhood‐level characteristics. Results suggest that foreign‐born Mexican men receive a wage premium from civic participation (bridging social capital) and a wage penalty from reciprocal social network exchange (bonding social capital). We also find that unauthorized legal status (among Mexican men and all migrants) and having children (among women) were negatively associated with hourly wages. We conclude with a discussion of the relative association of human and social capital with Mexican migrant wages.     

The unauthorized Mexican immigrant population and welfare in Los Angeles County: a comparative statistical analysis

"Using a unique 1994 Los Angeles County Household Survey of foreign-born Mexicans and the March 1994 and 1995 Current Population Surveys, we estimate the number of unauthorized Mexican immigrants (UMIs) residing in Los Angeles County, and compare their use of seven welfare programs with that of other non-U.S. citizens and U.S. citizens. Non-U.S. citizens were found to be no more likely than U.S. citizens to have used welfare, and UMIs were 11% (14%) less likely than other non-citizens (U.S.-born citizens).... We demonstrate how results differ depending on the unit of analysis employed, and on which programs constitute ?welfare'."     

Gender, acculturation, and health among Mexican Americans

This study examines whether the relationship between acculturation and physical health varies by gender among Mexican Americans, and if the mechanisms that mediate the acculturation-health relationship operate differently by gender. Using the 1998-2007 National Health Interview Study, we construct a composite measure of acculturation and estimate regression models for the total number of health conditions, hypertension, heart disease, and diabetes. Immigrants with the lowest levels of acculturation are the healthiest, but this association is stronger for men. Medical care plays a central role in accounting for gender and acculturation differences across health outcomes-increased access to and utilization of medical care is associated with worse health, which suggests that better health among recent arrivals (particularly men) partially results from their lack of knowledge about their own poor health.     

Religious Involvement and Physical Functioning among Older Mexican Americans

BACKGROUND AND PURPOSE: Examine the association between attendance at religious services and incidence of ADL disability over a period of seven years among older Mexican Americans 65 years and older. METHODS: Using data from the Hispanic Established Population for the Epidemiological Study of the Elderly (H-EPESE), logistic generalized estimation equation (GEE) models were used to analyze the contribution of attendance at religious services to the differences in incidence of ADL disability over seven years, controlling for demographics, medical conditions, and physical mobility. RESULTS: Frequent attendees at religious services had 30% lower odds of developing ADL disability over seven years compared to the non-regular attendance group. The odds were reduced to 23%, but remained significant when physical and mental health were controlled. CONCLUSIONS: In this older Mexican American population, regular attendees at religious services were less likely to develop ADL disability over a period of seven years compared to those who attended services less often.     

洛杉矶的地面公交

洛杉矶是美国最大的集合城市之一。低密度扩散的土地使用政策使居民的居住点分散在范围很大的土地上,居民的出行都要依赖私人交通。交通拥堵和空气污染的问题日益严重,发展公共交通必须摆到议事日程。自20世纪90年代初以来,洛杉矶陆续建造了4条轨道交通线,但是轨道交通的服务范围所能覆盖的还不到洛杉矶整个面积的10％。大部分地区的公共交通主要依靠公共汽车,而公共汽车的服务质量则在不断下降。受到交通拥堵的影响,从80年代开始,公共汽车的运行速度平均每年降低1％。     

Comparison of two methods for estimating the number of undocumented Mexican adults in Los Angeles County

This article compares 2 different methods for estimating the number of undocumented Mexican adults in Los Angeles County. The 1st method, the survey-based method, uses a combination of 1980 census data and the results of a survey conducted in Los Angeles County in 1980 and 1981. A sample was selected from babies born in Los Angeles County who had a mother or father of Mexican origin. The survey included questions about the legal status of the baby's parents and certain other relatives. The resulting estimates of undocumented Mexican immigrants are for males aged 18-44 and females aged 18-39. The 2nd method, the residual method, involves comparison of census figures for aliens counted with estimates of legally-resident aliens developed principally with data from the Immigration and Naturalization Service (INS). For this study, estimates by age, sex, and period of entry were produced for persons born in Mexico and living in Los Angeles County. The results of this research indicate that it is possible to measure undocumented immigration with different techniques, yet obtain results that are similar. Both techniques presented here are limited in that they represent estimates of undocumented aliens based on the 1980 census. The number of additional undocumented aliens not counted remains a subject of conjecture. The fact that the proportions undocumented shown in the survey (228,700) are quite similar to the residual estimates (317,800) suggests that the number of undocumented aliens not counted in the census may not be an extremely large fraction of the undocumented population. The survey-based estimates have some significant advantages over the residual estimates. The survey provides tabulations of the undocumented population by characteristics other than the limited demographic information provided by the residual technique. On the other hand, the survey-based estimates require that a survey be conducted and, if national or regional estimates are called for, they may require a number of surveys. The residual technique, however, also requires a data source other than the census. However, the INS discontinued the annual registration of aliens after 1981. Thus, estimates of undocumented aliens based on the residual technique will probably not be possible for subnational areas using the 1990 census unless the registration program is reinstituted. Perhaps the best information on the undocumented population in the 1990 census will come from an improved version of the survey-based technique described here applied in selected local areas.     

Religion, suffering, and health among older Mexican Americans

Pain and suffering are deeply embedded in the ethos of Mexican American culture. Consequently, it is not surprising to find that many Mexican Americans turn to their faith in an effort to deal with the pain and suffering that arise in their lives. The purpose of the current study is to explore the interface between pain, suffering, religion, and health among older Mexican Americans. Three major themes emerged from in-depth qualitative interviews with 52 older Mexican Americans. The first is concerned with whether pain and suffering are a necessary part of religious life, the second has to do with the potential benefits that pain and suffering may provide, and the third involves whether it is necessary to bear pain and suffering in silence. In the process of reviewing these themes, an effort is made to show how they may be linked with the physical and mental health of older Mexican Americans.     

Acculturation and Depressive Symptoms in Mexican American Couples

SUMMARY

Despite interest in examining the relationship between acculturation and depressive symptomatology among Latinos, limited attention has been given to these factors within the context of the Latino marital environment. The present study examines the role of acculturation in determining depressive symptoms among 173 married, Mexican American (MA) couples who participated in the 1992 Health and Retirement Survey, Wave I, while holding relevant variables (i.e., age, years of formal education, logged lower body difficulties, logged household income, logged household net worth, and logged household size) constant.

Aspects of acculturation are measured both at the individual level (language used during interview and nativity) and couple level (dyad concordance on language preference and nativity). Multilevel analysis revealed significant correlation between spouses' depressive symptomatology (intraclass correlation, ρ = .41), suggesting that the study of depressive symptoms in MA couples requires attention to their interpersonal contexts. Contrary to expectation, acculturation, logged household size, and socioeconomic variables (education, logged household income, and logged household net worth wealth) were not significantly associated with depressive symptoms. Age and logged lower body disability were significantly associated with depressive symptoms. Discussion focuses on the importance and challenge of assessing acculturation when exploring risk and protective factors on depressive symptomatology among mid-life and older MA couples.

Transnational Twist: Pecuniary Remittances and the Socioeconomic Integration of Authorized and Unauthorized Mexican Immigrants in Los Angeles County1

Annual U.S.‐Mexico pecuniary remittances are estimated to have more than doubled recently to at least $10 billion ‐ augmenting interest among policymakers, financial institutions, and transnational migrant communities concerning how relatively poor expatriate Mexicans sustain such large transfers and the impact on immigrant integration in the United States. We employ the 2001 Los Angeles County Mexican Immigrant Residency Status Survey (LAC‐MIRSS) to investigate how individual characteristics and social capital traditionally associated with integration, neighborhood context, and various investments in the United States influenced remitting in 2000. Remitting is estimated to have been inversely related to conventional integration metrics and influenced by community context in both sending and receiving areas. Contrary to straight‐line assimilation theories and more consistent with a transnational or nonlinear perspective, however, remittances are also estimated to have been positively related to immigrant homeownership in Los Angeles County and negatively associated with having had public health insurance such as Medicaid.     

Acculturation and Risk Behavior among Pregnant Mexican American Females: A Structural Equation Model

The purpose of this study was to test a theoretical model designed to predict risk behavior (i.e., cigarette and/or alcohol use) in a sample of Mexican American females who were pregnant and ranged in age from adolescence to early adulthood. The model consisted of six hypothesized predictors–acculturation status, intergenerational family conflict, acculturative stress, educational attainment, household income, and age of respondent, which were proposed as antecedents of risk behavior. Structural equation modeling was used to test both the direct and indirect effects for a set of proposed antecedents to the tendency for Mexican American females to engage in risk behaviors. Several of the hypothesized relationships were supported, with the strongest predictors of risk behavior being acculturation status, intergenerational family conflict, and acculturative stress. An important conclusion was that risk behavior by Mexican American females increased as they became more acculturated to the social circumstances of the U.S. Another notable result was that risk behavior increased among Mexican American females as they experienced higher levels of intergenerational conflict within their families.     

An Analysis of Differential Assimilation Rates among Middle-class Mexican Americans*

The investigation focused on the identification of variables which might help explain differential assimilation rates among middle-class Mexican Americans. The data were collected from a random probability sample of 151 middle-class Mexican Americans residing in Waco, Austin. McAllen, and Lubbock, Texas. Three Likert-type scales designed to measure various components of the assimilation process were developed out of items abstracted from standardized interview schedules. The multiple correlation technique was used to identify independent variables which contributed significantly to a regression model for explaining variation in scores on each of the three scales. The findings suggested that early socialization patterns incorporating a discontinuous status sequence and a lack of reinforcement as Mexican-American increase the probability that the individual will assimilate into the broader American cultural system.     

The industrial division of labor among immigrants and internal migrants to the Los Angeles economy

This study examined the industrial division of labor among immigrants and in-migrants in the Los Angeles, California, metropolitan area. It addresses debates about channeling of new arrivals into jobs among similar ethnic groups and human capital views. Data were obtained from the 1990 Census on resident native-born, resident foreign-born, in-migrants, and recent immigrants who arrived during 1985-90. Light and Rosenstein's (1995) concepts of groups and their resources were used to organize ideas about ethnic networks and their effectiveness in channeling migrant workers into 15 industrial sectors. Sectoral differences were revealed with the familiarity index of dissimilarity. Findings reveal that social networks were the strongest for Koreans, who supplied work for recent arrivals in the same sectors as Korean-born residents, regardless of education. Mexican new arrivals were less likely to work in the same sectors as their resident Mexican counterparts. Mexican networks placed new arrivals in durable manufacturing in the 1960s and 1970s when it was a key source of employment. By the 1980s and 1990s, the economy shifted and employment went down in durable manufacturing. Mexicans thus found employment elsewhere. Native White and Black in-migrants had the strongest channeling into same sector jobs. This is attributed to the small streams, the ability of the labor market to absorb these workers, and the availability of job vacancies among native out-migrants. Filipino migrants had similar patterns as Whites and Blacks. Mexican and Central American residents had more inter-ethnic competition over jobs than Whites or Blacks.     

The energy and mass balance of Los Angeles County

We conducted an urban “metabolic” study of inputs and outputs of food, water, energy, and pollutants from Los Angeles County, USA. This region has been the subject of recent debate about the nature of population density and distribution as it relates to urban form and associated environmental impacts. We found that with the exception of food imports and wastewater outputs, inputs of resources and outputs of pollutants generally declined on a per capita basis from 1990 to 2000. Reductions likely reflected a combination of changes in public policy, improvements in technology and public infrastructure, and impacts of increases in population density. However, in comparison to other municipalities and urban regions, resource consumption per capita was still relatively high in some categories, particularly inputs of water and transportation energy. Per capita greenhouse gas emissions were lower in Los Angeles County than for the average of the USA as a whole but higher than previous analyses of urban areas internationally, largely due to comparatively high emissions from the transportation sector. Wastewater discharge accounted for less than 40% of water inputs excluding precipitation; however the partitioning of water outputs through other potential losses, specifically evapotranspiration, runoff, and groundwater recharge, remains highly uncertain. We suggest that more detailed information about water losses will greatly improve future mass and energy accounting for analyses of urban environmental sustainability in this semi-arid region.     

Immigrant incorporation in the garment industry of Los Angeles

This study expands immigrant social network theory and examined employment patterns in the garment industry in Los Angeles, California, among Latino workers employed by Asian immigrant entrepreneurs. The study determined that a large percentage of immigrant employees found their jobs through the immigrant economy. Entrepreneurship increased the supply of local jobs and expanded the economy at destination at no expense to natives. Immigrant entrepreneurs bought firms from nonimmigrant owners or started new ones with an immigrant labor supply. Massey's index is flawed due to its exclusion of the role of entrepreneurs. Migration networks facilitate entrepreneurship, but some ethnic groups have fewer entrepreneurs, such as Mexicans and Central Americans. A 1993 Los Angeles survey identified 3642 garment factories in its county. Mean employment was 27.1 persons. The garment industry was the 4th largest industry in the area in 1996, with 98,700 employees. It represented 6% of all wage and salary employees in the City and 5.5% of the immigrant labor force in the County in 1990. 93% of garment workers in 1990 were immigrants. It is estimated that 51% of garment factory owners were Asians; most employees were Latinos. Census figures on sewing machine operators indicated 47.3% of owners were Whites and 42.45 were Asians. 53.3% of employees were other ethnic groups, 14.5% were Asians, and 32.2% were Whites. It is estimated that 47.2% of total employment was due to the immigration economy. 71.5% of the total employment in the garment industry was in the immigrant sector.     

A time series of urban forestry in Los Angeles

There has been an increasing interest in the evolution of urban forests. This research uses historic and digital aerial photography to quantify changes in tree density in Los Angeles, California since the 1920’s. High-resolution geographic information system analysis (4 to 6 time periods) of three regions (San Fernando Valley, Hollywood, Los Angeles Basin) of Los Angeles reveals that there has not always been an increase in tree density with time. Tree densities on public and private land were highest in the 1940’s in Hollywood, while the San Fernando Valley and Los Angeles Basin experienced a near linear increase in tree density on both private and public land since the 1920’s. When historic tree density reconstructions were examined for the 15 Los Angeles city council districts from the 1920’s, 1950’s and 2006, most districts in Los Angeles have experienced a significant increase in tree density, however, there has been wide variation in tree densities among city council districts. Trees densities have generally been higher on private land since the 1920’s and currently tree densities on private land are significantly higher than on public land. Results suggest the evolution of urban forests in Los Angeles mirrors the dynamics of urban forests in desert and grassland cities. It is possible to reconstruct the development of urban forests in sections of cities using historic and contemporary aerial photography. We estimated that Los Angeles averages approximately 104 trees per hectare (82 private land, 22 public land) based on 2006 imagery at 0.3 m resolution, however, field validation suggests that we identified only 73% of trees. Although there is still space to plant trees on public land, private land owners will need to be heavily involved in order to achieve the goals of Los Angeles’ Million Tree Initiative.
