Studies of urban ethnic enclaves, or residential areas where minorities experience cohesion as a group, are growing in popularity in the present era of globalization, which is marked by historically high rates of migration. Such studies almost universally treat the ethnic groups in question in relation to the "host societies" or "charter groups" that constitute the historically dominant peoples of the regions in which migrants settle (Pacione 2001: 362-366). In the case of ethnic enclaves of the United States, the host society is usually, but not always, Anglo. Mike Davis (2000), for example, shows us that traditionally black inner-city areas can become Latino-dominant enclaves as blacks migrate to suburbs, as has occurred in greater Los Angeles, New York, and other northern cities. Thus, as demonstrated throughout this volume, most Latino communities, whether urban or rural, have recently been established and, in many cases, constitute a new phase of the filtering process in historically Anglo or black areas of cities. Such is not the case, however, with Laredo, Texas, a historically Hispanic city comprising multiple generations of continuous occupation by Spaniards, Mexicans, and their offspring. This reality calls for a somewhat distinctive approach to the study of the Hispanic geography of Laredo, a city located directly on the border between Texas and Mexico. In Lower Rio Grande Valley cities of Texas such as McAllen, Brownsville, and Har-lingen, Anglo majorities historically dominated the community's social and economic structure. A Hispanic underclass existed chiefly as labor, and, with few exceptions, a Hispanic middle class has only recently emerged. In Laredo, on the other hand, Hispanics have been dominant politically and socially for three centuries and, as a result, have constructed the social geography of the city and its surrounding rural hinterland (Arreola 2002). Accordingly, this chapter examines the social geography of Laredo's neighborhoods and the increasing socioeconomic disparities that occur within the majority-Hispanic city. Such an approach will demonstrate the relatively unusual role that ethnicity and ethnic relations play in the social construction of this highly stratified community. Our study reveals that Laredo's historical isolation from other population centers in Texas and Mexico has created a geographical distinctiveness in this border city. Shared cultural traits transcend social class in Laredo, yet there are a variety of lifestyles and urban-design elements seen throughout the metropolitan area. When Yoder recently announced in a lower-division college world geography class comprising predominantly Laredoans that the Latino population of the United States had reached parity with that of African Americans, surprisingly few of the students in the class reacted in any visible way. Follow-up questions posed on the spot produced the same result. It would be reasonable to regard this as an indication that the average world-view of students born in Laredo is framed more in terms of Laredo than of "mainstream" Anglo America. Ethnic identity among Laredo's Mexican Americans is quite unlike what is found in Los Angeles, Houston, or other American cities with sizable Latino populations. One might argue that Laredo represents a departure from the cultural norms of mainstream America and, as such, exhibits a relationship between a distinctive group of people and their place that is typical of ethnic enclaves (Abrahamson 1996: 2). Many Laredoans identify with the particular place they occupy. Just as Latino enclaves within American cities are defined by language, local cuisine, family-run retail shops, architecture, and the like, Laredo is unique as an American city by virtue of such traits. Furthermore, despite strong kinship ties that bind the entire city, people nonetheless identify with particular neighborhoods in Laredo (Valdez 1993). This is especially evident in the dichotomy between the South Laredo of working-class barrios and low-income subdivisions and the North Laredo of middle- and upper-middle-class subdivisions and fast-paced, automobile-oriented commercial land uses that typify mainstream North American suburban style, or "suburbia Americana." In this chapter, we provide a brief overview of Laredo's settlement history, particularly those aspects that underlie the city's unique character among Hispanic places. The discussion then turns to a description of the contemporary Laredo economy and the city's role in international trade insofar as these relate to social variability throughout the city. We describe the various sectors of the city and its neighborhoods and discuss pertinent aesthetic and lifestyle characteristics, such as housing, with attention to spatial patterns. Case studies of five neighborhoods, from working class to upper middle class, indicate the unique character of each of Laredo's many inner-city barrios and suburban subdivisions. Significantly, the case studies also shed light on the universality of many cultural practices throughout Laredo, lifestyle preferences, and kinship patterns that transcend social class. Examination of the social geography of neighborhoods enables researchers better to understand the dynamics that occur between and among the various social classes that make up a city whose citizenry is 94 percent Hispanic, 37 percent of whom lived below the poverty line in 1990 (U.S. Bureau of the Census 1992; Valdez 1993).
