This book is a detailed comparative analysis of development politics in four urban regions of Latin America, two in Mexico and two in Colombia. John Walton has based his studies on the assumption that the problems of economic growth are essentially political, that is, are problems of choice, decision-making, and the exercise of power. His fundamental purpose has been to discover how elites of different kinds are more and less successful in the promotion of economic development, which he defines as a process in the organization of a society leading not only to higher levels of efficient output but also to a more equitable distribution of benefits.

At the time, the four cities compared were the second- and third-largest metropolitan areas in each country, Guadalajara and Monterrey in Mexico, Medellín and Cali in Colombia. This selection allows the author to pair, across countries, cases of early and large-scale industrialization (Monterrey and Medellín) with cases of more recent industrial growth in agricultural-commercial centers (Guadalajara and Cali). Walton presents historical introductions to each of the regions and integrates these with original fieldwork and interviews with more than three hundred members of the political and economic elites.

The findings are extensive, but in general they demonstrate that where political and economic power is more broadly distributed, where elites are more open and accessible, and where organizational life is more active and coordinated, regions tend to develop qualitatively as well as quantitatively, showing increases both in productivity and in such benefits as public services, housing, education, and a more balanced distribution of income. If these characteristics are absent, regions may be industrialized but do not provide a broad sharing of the benefits. Walton places a good deal of emphasis on the role of foreign investments, demonstrating that the more penetrated regions are also the less developed.

Finally, the results of these studies are used to evaluate and advance theories of underdevelopment and particularly of economic dependency.

Much research on the city in developing societies has focused mainly on one of three areas—planning, demography, or economics—and has emphasized either power elites or the masses, but not both. The published literature on Latin America has reflected these interests and has so far failed to provide a comprehensive view of Latin American urbanization. Urban Latin America is an attempt to integrate research on Latin American social organization within a single theoretical framework: development as fundamentally a political problem. Alejandro Portes and John Walton have included material on both elites and marginal populations and on the three major areas of research in order to formulate and address some of the key questions about the structure of urban politics in Latin America.

Following an introduction that delineates the scope of Latin American urban studies, Portes discusses the Latin American city as a creation of European colonialism. He goes on to examine political behavior among the poor, with central reference to system support and countersystem potential. Walton provides material for a comparative study of four cities: Monterrey and Guadalajara in Mexico and Medellín and Cali in Colombia. He also summarizes a large number of urban elite studies and develops a theoretical interpretation of their collective results, based on class structure and vertical integration. Material in each chapter is cross-referenced to other chapters, and the authors have used a common methodological approach in synthesizing and interpreting the research literature. In the final chapter they generalize current findings, elaborating on the interface between elite and mass politics in the urban situation. They make some observations on approaching changes and pinpoint possible research strategies for the future.
