Sunnyvale sits in the heart of Silicon Valley between San Jose and Mountain View, bordered by El Camino Real to the east and stretching west toward the bay. The city encompasses distinct areas from the Moffett Park office corridor near NASA Ames Research Center to the residential neighborhoods around Lakewood and the Cherry Chase district. Major employers include tech companies, defense contractors, and the sprawling campuses along Mathilda Avenue and Lawrence Expressway, with Caltrain providing direct access to San Francisco and the Peninsula. The population includes long-established families, tech workers, and a significant Asian American community, particularly concentrated around Murphy Avenue downtown.
