San Diego (SAN dee-AY-goh, Spanish: [san djeo]; Spanish for 'Saint Didacus') is a city on the Pacific Ocean coast of Southern California. With a 2020 population of 1,386,932, it is the eighth most populous city in the United States. San Diego is the economic center of the San DiegoTijuana conurbation, the second most populous transborder metropolitan area in the Western Hemisphere. The primary border crossing between San Diego and Tijuana, the San Ysidro Port of Entry, is the busiest international land border crossing in the world outside of Asia. The city is known for its mild year-round climate, natural deep-water harbor, extensive beaches and parks, and recent emergence as a healthcare and biotechnology development center. The first European to visit the region was explorer Juan Rodríguez Cabrillo, sailing under the flag of Castile but possibly born in Portugal. The Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly declared Mexican Empire, which reformed as the First Mexican Republic two years later. California was admitted to the union as a state in 1850 and became the state of California in 1848 following the MexicanAmerican War. The original inhabitants of the region are now known as the San Dieguito and La Jolla people. The Kumeyaay people migrated into the area of San Diego around 1000 CE.


San Diego is the primary city name, but also Nas N Island, Nas North Island are acceptable city names or spellings. The official name is City of San Diego. The original inhabitants of the region are now known as the San Dieguito and La Jolla people. The first European to visit the region was explorer Juan Rodríguez Cabrillo, sailing under the flag of Castile but possibly born in Portugal. In November 1602, Sebastián Vizcaíno was sent to map the California coast. The permanent European colonization of both California and San Diego began in 1769 with the arrival of four contingents of Spaniards from New Spain and the Baja California peninsula. In July of the same year, Mission San Diego de Alcalá was founded by Franciscan friars under Serra. The mission became a site for a Kumeyaay revolt in 1775, which forced the mission to relocate six miles (10 km) up the San Diego River. By 1797, the mission boasted the largest native population in Alta California, with over 1,400 neophytes living in and around the mission proper. The Mission was secularized by the Mexican government in 1834, and most of the Mission lands were granted to former soldiers. By 1838, San Diego had been losing population throughout 1830, and in 1838 the town lost its pueblo status because its size dropped to an estimated 100 to 150 residents. Between the late 1830s and the 1840s, the town would face raids in the North-Western Coast of America, often officially forbidden to foreigners. San Diego was a major port and the only one with an adequate harbor.


The city lies on approximately 200 deep canyons and hills separating its mesas. The San Diego River runs through the middle of San Diego from east to west, creating a river valley that serves to divide the city into northern and southern segments. Cowles Mountain, the highest point in the city limits, is at 1,591 feet (485 m) The city was originally centered on the Old Town district, but by the late 1860s the focus had shifted to the bayfront, in the belief that this new location would increase trade.
