Los Angeles sprawls across 469 square miles of coastal Southern California, from the Pacific beaches of Venice and Santa Monica through downtown's financial district to the San Gabriel Valley communities of Pasadena and Glendale. The nation's second-largest city anchors a massive metropolitan region that includes the San Fernando Valley to the north, the South Bay cities stretching to Long Beach, and eastern neighborhoods reaching toward San Bernardino County. The economy runs on entertainment production, international trade through the ports, aerospace and defense manufacturing, healthcare systems, and professional services, with major employment centers in Century City, Burbank's media corridor, and the downtown Arts District.
