context_page_description: San Diego–Tijuana is an international transborder agglomeration, straddling the border of the adjacent North American coastal cities of San Diego, California, United States and Tijuana, Baja California, Mexico. The 2012 population of the region was 4,922,723, making it the largest bi-national conurbation shared between the United States and Mexico, the third-largest shared between the US and another country, and the fourth-largest in the world. In its entirety, the region consists of San Diego County in the United States and the municipalities of Tijuana, Rosarito Beach, and Tecate in Mexico. It is the third most populous region in the California–Baja California region, smaller only than the metropolitan areas of Greater Los Angeles and the San Francisco Bay Area.
  The largest centers of the urban area maintain global city status and as a whole the metropolitan region is host to 13 consulates from Asian, European, North American, Oceanian, and South American nations. Over fifty million people cross the border each year between Tijuana and San Diego, giving the region the busiest land-border crossing in the world.
context_section_description: The economy of the urban area is influenced by the Port of San Diego which gives the region a strong maritime sector; the conurbation is the location of the only major submarine and shipbuilding yards on the West Coast and of the largest naval fleet in the world. The cruise ship industry, which is the second largest in the California-Baja California region, generates an estimated $2 million annually from the purchase of food, fuel, supplies, and maintenance services. In California alone, the port is the fastest-growing port in terms of cruise ship dockings and the second largest behind the Port of Los Angeles.
