ABSTRACT
The San Diego global city region, in reality, is a binational region consisting of two cities—San Diego, California, in the United States, and Tijuana, Baja California, in Mexico—as well as suburbs on both sides of the border. Together, the region has a population of over 3.5 million and 1.5 million jobs; and, the county of San Diego is expected to grow by 1 million residents by 2020. The Tijuana region may grow by a similar amount in the same period. Many issues and problems are common to both areas and require joint planning and solutions. Both cities are at the edge of their countries. San Diego is at the southwest corner of the United States—south of southern California—a distinction that is very important to its residents. Tijuana is at the northwest corner of Mexico and bears little resemblance to the interior cities of Mexico. As a region, both cities see themselves as the gateway to Mexico and to the United States and jointly as a principal location on the Pacific Rim.
