Santa Ana, the seat of California's Orange County, is the center of an area known as "the Golden Corridor." Surrounded by the rich farmland of the Santa Ana Valley, the city is part of a megalopolis that includes several incorporated cities; among them are Anaheim, Buena Park, and Fullerton. It is close to both the Los Angeles metropolitan area to the northwest and the San Diego metropolitan area to the southeast along the Pacific Coast. More than 76 percent of its residents are of Hispanic origin; thus, Santa Ana has retained its rich cultural heritage. Founded as a farming town, the city is now the financial and governmental center for Orange County.
