The population of the entire county in 2010 was 423,895.In addition to being a popular tourist and resort destination, the city economy includes a large service sector, education, technology, health care, finance, agriculture, manufacturing, and local government. In 2004, the service sector accounted for fully 35% of local employment. Education in particular is well-represented, with five institutions of higher learning on the south coast (the University of California, Santa Barbara, Santa Barbara City College, Westmont College, Antioch University, and the Brooks Institute of Photography.) The Santa Barbara Airport serves the city, as does Amtrak. U.S. Highway 101 connects the Santa Barbara area with Los Angeles to the south and San Francisco to the north.
