San Diego /ˌsæn diːˈeɪɡoʊ/ is the eighth-largest city in the United States and second-largest city in California. The city is located on the coast of the Pacific Ocean in Southern California, immediately adjacent to the Mexican border. The birthplace of California, San Diego is known for its mild year-round climate, natural deep-water harbor, extensive beaches, long association with the U.S. Navy, and recent emergence as a healthcare and biotechnology enclave. The population was 1,301,617 at the 2010 census.
Historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Cabrillo claimed the entire area for Spain, forming the basis for the settlement of Alta California 200 years later. The Presidio and Mission of San Diego, founded in 1769, were the first European settlement in what is now California. In 1821, San Diego became part of newly independent Mexico, and in 1850, became part of the United States following the Mexican-American War and the admission of California to the union.
Tijuana (/tiːəˈwɑːnə/ tee-ə-WAH-nə or /tiːˈwɑːnə/; Spanish: [tiˈxwana]) is the largest city on the Baja California Peninsula and center of the Tijuana metropolitan area, part of the international San Diego–Tijuana metropolitan area. An industrial and financial center of Mexico, Tijuana exerts a strong influence on economics, education, culture, art, and politics. As the city has become a leading center in the country, so has the surrounding metropolitan area, a major industrial and paramount metropolis in northwestern Mexico. Currently one of the fastest growing cities in Mexico, Tijuana maintains global city status.
On the Gold Coast of Baja California, Tijuana is the municipal seat, cultural, and commercial center of Tijuana Municipality. A dominant manufacturing center of the North American continent, the city maintains facilities of numerous multinational conglomerate companies. The 2000's saw Tijuana become the medical device manufacturing capital of North America. Also a growing cultural center, Tijuana has been recognized as one of most important new cultural meccas. The city is the most visited border city in the globe; sharing an approximate 24-kilometre-long border (15 mi) with its sister city San Diego, over fifty million people annually cross the border between these two cities. This metropolitan crossing makes the San Ysidro Port of Entry the busiest land-border crossing in the world. It is estimated that the two border crossing stations between the cities proper of San Diego and Tijuana account for 300,000 daily border crossings alone.
