San Diego ( san-_-dee-AY-goh Spanish for Saint Didacus) is a city in the U.S. state of California on the coast of the Pacific Ocean and immediately adjacent to the Mexican border. With a 2020 population of 1,386,932, San Diego is the eighth most populous city in the United States and second most populous in California (after Los Angeles). The city is the county seat of San Diego County, the fifth most populous county in the United States, with 3,338,330 estimated residents as of 2019. The city is known for its mild year-round climate, natural deep-water harbor, extensive beaches and parks, long association with the United States Navy and Marine Corps, and recent emergence as a healthcare and biotechnology development center.
Historically home to the Kumeyaay people, San Diego is frequently referred to as the "Birthplace of California", as it was the first site visited and settled by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain, forming the basis for the settlement of Alta California 200 years later. 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 became part of the United States in 1848 following the Mexican–American War and was admitted to the union as a state in 1850.
San Diego's main economic engines are military and defense-related activities, tourism, international trade, research, and manufacturing. The city is the economic center of the San Diego–Tijuana conurbation, the second most populous transborder metropolitan area in the western hemisphere (after Detroit–Windsor), home to an estimated 4,922,723 people as of 2012. 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 (fourth-busiest overall). The city's primary airport, San Diego International Airport, is the busiest single-runway airport in the world.

The first European to visit the region was Portuguese-born explorer Juan Rodríguez Cabrillo sailing under the flag of Castile. Sailing his flagship San Salvador from Navidad, New Spain, Cabrillo claimed the bay for the Spanish Empire in 1542, and named the site "San Miguel". In November 1602, Sebastián Vizcaíno was sent to map the California coast. Arriving on his flagship San Diego, Vizcaíno surveyed the harbor and what are now Mission Bay and Point Loma and named the area for the Catholic Saint Didacus, a Spaniard more commonly known as San Diego de Alcalá. On November 12, 1602, the first Christian religious service of record in Alta California was conducted by Friar Antonio de la Ascensión, a member of Vizcaíno's expedition, to celebrate the feast day of San Diego.
In May 1769, Gaspar de Portolà established the Fort Presidio of San Diego on a hill near the San Diego River. It was the first settlement by Europeans in what is now the state of California. In July of the same year, Mission San Diego de Alcalá was founded by Franciscan friars under Junípero Serra. By 1797, the mission boasted the largest native population in Alta California, with over 1,400 neophytes living in and around the mission proper. Mission San Diego was the southern anchor in California of the historic mission trail El Camino Real. Both the Presidio and the Mission are National Historic Landmarks.
In 1821, Mexico won its independence from Spain, and San Diego became part of the Mexican territory of Alta California. In 1822, Mexico began attempting to extend its authority over the coastal territory of Alta California. The fort on Presidio Hill was gradually abandoned, while the town of San Diego grew up on the level land below Presidio Hill. The Mission was secularized by the Mexican government in 1833, and most of the Mission lands were sold to wealthy Californio settlers. The 432 residents of the town petitioned the governor to form a pueblo, and Juan María Osuna was elected the first alcalde ("municipal magistrate"), defeating Pío Pico in the vote. (See, List of pre-statehood mayors of San Diego.) However, San Diego had been losing population throughout the 1830s and in 1838 the town lost its pueblo status because its size dropped to an estimated 100 to 150 residents. Beyond town Mexican land grants expanded the number of California ranchos that modestly added to the local economy.
In 1846, the United States went to war against Mexico and sent a naval and land expedition to conquer Alta California. At first they had an easy time of it capturing the major ports including San Diego, but the Californios in southern Alta California struck back. Following the successful revolt in Los Angeles, the American garrison at San Diego was driven out without firing a shot in early October 1846. Mexican partisans held San Diego for three weeks until October 24, 1846, when the Americans recaptured it. For the next several months the Americans were blockaded inside the pueblo. Skirmishes occurred daily and snipers shot into the town every night. The Californios drove cattle away from the pueblo hoping to starve the Americans and their Californio supporters out. On December 1 the Americans garrison learned that the dragoons of General Stephen W. Kearney were at Warner's Ranch. Commodore Robert F. Stockton sent a mounted force of fifty under Captain Archibald Gillespie to march north to meet him. Their joint command of 150 men, returning to San Diego, encountered about 93 Californios under Andrés Pico. In the ensuing Battle of San Pasqual, fought in the San Pasqual Valley which is now part of the city of San Diego, the Americans suffered their worst losses in the campaign. Subsequently, a column led by Lieutenant Gray arrived from San Diego, rescuing Kearny's battered and blockaded command.
Stockton and Kearny went on to recover Los Angeles and force the capitulation of Alta California with the "Treaty of Cahuenga" on January 13, 1847. As a result of the Mexican–American War of 1846–48, the territory of Alta California, including San Diego, was ceded to the United States by Mexico, under the terms of the Treaty of Guadalupe Hidalgo in 1848. The Mexican negotiators of that treaty tried to retain San Diego as part of Mexico, but the Americans insisted that San Diego was "for every commercial purpose of nearly equal importance to us with that of San Francisco," and the Mexican–American border was eventually established to be one league south of the southernmost point of San Diego Bay, so as to include the entire bay within the United States.
The state of California was admitted to the United States in 1850. That same year San Diego was designated the seat of the newly established San Diego County and was incorporated as a city. Joshua H. Bean, the last alcalde of San Diego, was elected the first mayor. Two years later the city was bankrupt; the California legislature revoked the city's charter and placed it under control of a board of trustees, where it remained until 1889. A city charter was re-established in 1889 and today's city charter was adopted in 1931.
The original town of San Diego was located at the foot of Presidio Hill, in the area which is now Old Town San Diego State Historic Park. The location was not ideal, being several miles away from navigable water. In 1850, William Heath Davis promoted a new development by the Bay shore called "New San Diego", several miles south of the original settlement; however, for several decades the new development consisted only a few houses, a pier and an Army depot. In the late 1860s, Alonzo Horton promoted a move to the bayside area, which he called "New Town" and which became Downtown San Diego. Horton promoted the area heavily, and people and businesses began to relocate to New Town because of its location on San Diego Bay convenient to shipping. New Town soon eclipsed the original settlement, known to this day as Old Town, and became the economic and governmental heart of the city. Still, San Diego remained a relative backwater town until the arrival of a railroad connection in 1878.
In the early part of the 20th century, San Diego hosted two World's Fairs: the Panama-California Exposition in 1915 and the California Pacific International Exposition in 1935. Both expositions were held in Balboa Park, and many of the Spanish/Baroque-style buildings that were built for those expositions remain to this day as central features of the park. The buildings were intended to be temporary structures, but most remained in continuous use until they progressively fell into disrepair. Most were eventually rebuilt, using castings of the original façades to retain the architectural style. The menagerie of exotic animals featured at the 1915 exposition provided the basis for the San Diego Zoo. During the 1950s there was a citywide festival called Fiesta del Pacifico highlighting the area's Spanish and Mexican past. In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but the plans were abandoned when the organization tasked with putting on the celebration went out of business.
The southern portion of the Point Loma peninsula was set aside for military purposes as early as 1852. Over the next several decades the Army set up a series of coastal artillery batteries and named the area Fort Rosecrans. Significant U.S. Navy presence began in 1901 with the establishment of the Navy Coaling Station in Point Loma, and expanded greatly during the 1920s. By 1930, the city was host to Naval Base San Diego, Naval Training Center San Diego, San Diego Naval Hospital, Camp Matthews, and Camp Kearny (now Marine Corps Air Station Miramar). The city was also an early center for aviation: as early as World War I, San Diego was proclaiming itself "The Air Capital of the West". The city was home to important airplane developers and manufacturers like Ryan Airlines (later Ryan Aeronautical), founded in 1925, and Consolidated Aircraft (later Convair), founded in 1923. Charles A. Lindbergh's plane The Spirit of St. Louis was built in San Diego in 1927 by Ryan Airlines.
During World War II, San Diego became a major hub of military and defense activity, due to the presence of so many military installations and defense manufacturers. The city's population grew rapidly during and after World War II, more than doubling between 1930 (147,995) and 1950 (333,865). During the final months of the war, the Japanese had a plan to target multiple U.S. cities for biological attack, starting with San Diego. The plan was called "Operation Cherry Blossoms at Night" and called for kamikaze planes filled with fleas infected with plague (Yersinia pestis) to crash into civilian population centers in the city, hoping to spread plague in the city and effectively kill tens of thousands of civilians. The plan was scheduled to launch on September 22, 1945, but was not carried out because Japan surrendered five weeks earlier.
After World War II, the military continued to play a major role in the local economy, but post-Cold War cutbacks took a heavy toll on the local defense and aerospace industries. The resulting downturn led San Diego leaders to seek to diversify the city's economy by focusing on research and science, as well as tourism.
From the start of the 20th century through the 1970s, the American tuna fishing fleet and tuna canning industry were based in San Diego, "the tuna capital of the world". San Diego's first tuna cannery was founded in 1911, and by the mid-1930s the canneries employed more than 1,000 people. A large fishing fleet supported the canneries, mostly staffed by immigrant fishermen from Japan, and later from the Portuguese Azores and Italy whose influence is still felt in neighborhoods like Little Italy and Point Loma. Due to rising costs and foreign competition, the last of the canneries closed in the early 1980s.
Downtown San Diego was in decline in the 1960s and 1970s, but experienced some urban renewal since the early 1980s, including the opening of Horton Plaza, the revival of the Gaslamp Quarter, and the construction of the San Diego Convention Center; Petco Park opened in 2004.
According to SDSU professor emeritus Monte Marshall, San Diego Bay is "the surface expression of a north-south-trending, nested graben". The Rose Canyon and Point Loma fault zones are part of the San Andreas Fault system. About 15 miles (24 km) east of the bay are the Laguna Mountains in the Peninsular Ranges, which are part of the backbone of the American continents.
The city lies on approximately 200 deep canyons and hills separating its mesas, creating small pockets of natural open space scattered throughout the city and giving it a hilly geography. Traditionally, San Diegans have built their homes and businesses on the mesas, while leaving the urban canyons relatively wild. Thus, the canyons give parts of the city a segmented feel, creating gaps between otherwise proximate neighborhoods and contributing to a low-density, car-centered environment. The San Diego River runs through the middle of San Diego from east to west, creating a river valley which serves to divide the city into northern and southern segments. The river used to flow into San Diego Bay and its fresh water was the focus of the earliest Spanish explorers. Several reservoirs and Mission Trails Regional Park also lie between and separate developed areas of the city.
Notable peaks within the city limits include Cowles Mountain, the highest point in the city at 1,591 feet (485 m); Black Mountain at 1,558 feet (475 m); and Mount Soledad at 824 feet (251 m). The Cuyamaca Mountains and Laguna Mountains rise to the east of the city, and beyond the mountains are desert areas. The Cleveland National Forest is a half-hour drive from downtown San Diego. Numerous farms are found in the valleys northeast and southeast of the city.
In its 2013 ParkScore ranking, The Trust for Public Land reported that San Diego had the 9th-best park system among the 50 most populous U.S. cities. ParkScore ranks city park systems by a formula that analyzes acreage, access, and service and investment.
Communities and neighborhoods
The city of San Diego recognizes 52 individual areas as Community Planning Areas. Within a given planning area there may be several distinct neighborhoods. Altogether the city contains more than 100 identified neighborhoods.
Downtown San Diego is located on San Diego Bay. Balboa Park encompasses several mesas and canyons to the northeast, surrounded by older, dense urban communities including Hillcrest and North Park. To the east and southeast lie City Heights, the College Area, and Southeast San Diego. To the north lies Mission Valley and Interstate 8. The communities north of the valley and freeway, and south of Marine Corps Air Station Miramar, include Clairemont, Kearny Mesa, Tierrasanta, and Navajo. Stretching north from Miramar are the northern suburbs of Mira Mesa, Scripps Ranch, Rancho Peñasquitos, and Rancho Bernardo. The far northeast portion of the city encompasses Lake Hodges and the San Pasqual Valley, which holds an agricultural preserve. Carmel Valley and Del Mar Heights occupy the northwest corner of the city. To their south are Torrey Pines State Reserve and the business center of the Golden Triangle. Further south are the beach and coastal communities of La Jolla, Pacific Beach, Mission Beach, and Ocean Beach. Point Loma occupies the peninsula across San Diego Bay from downtown. The communities of South San Diego, such as San Ysidro and Otay Mesa, are located next to the Mexico–United States border, and are physically separated from the rest of the city by the cities of National City and Chula Vista. A narrow strip of land at the bottom of San Diego Bay connects these southern neighborhoods with the rest of the city.
For the most part, San Diego neighborhood boundaries tend to be understood by its residents based on geographical boundaries like canyons and street patterns. The city recognized the importance of its neighborhoods when it organized its 2008 General Plan around the concept of a "City of Villages".
San Diego 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. As the "New Town" – present-day Downtown – waterfront location quickly developed, it eclipsed Old Town as the center of San Diego.
The development of skyscrapers over 300 feet (91 m) in San Diego is attributed to the construction of the El Cortez Hotel in 1927, the tallest building in the city from 1927 to 1963. As time went on multiple buildings claimed the title of San Diego's tallest skyscraper, including the Union Bank of California Building and Symphony Towers. Currently the tallest building in San Diego is One America Plaza, standing 500 feet (150 m) tall, which was completed in 1991. The downtown skyline contains no super-talls, as a regulation put in place by the Federal Aviation Administration in the 1970s set a 500 feet (152 m) limit on the height of buildings within a one-mile (1.6 km) radius of the San Diego International Airport. An iconic description of the skyline includes its skyscrapers being compared to the tools of a toolbox.
San Diego is one of the top-ten best climates in the Farmers' Almanac and is one of the two best summer climates in America as scored by The Weather Channel. Under the Köppen–Geiger climate classification system, the San Diego area has been variously categorized as having either a semi-arid climate (BSh in the original classification and BSkn in modified Köppen classification) or a Mediterranean climate (Csa and Csb). San Diego's climate is characterized by warm, dry summers and mild winters with most of the annual precipitation falling between December and March. The city has a mild climate year-round, with an average of 201 days above 70 °F (21 °C) and low rainfall (9–13 inches [230–330 mm] annually).
The climate in San Diego, like most of Southern California, often varies significantly over short geographical distances resulting in microclimates. In San Diego, this is mostly because of the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover keeps the air cool and damp within a few miles of the coast, but yields to bright cloudless sunshine approximately 5–10 miles (8.0–16.1 km) inland. Sometimes the June gloom lasts into July, causing cloudy skies over most of San Diego for the entire day. Even in the absence of June gloom, inland areas experience much more significant temperature variations than coastal areas, where the ocean serves as a moderating influence. Thus, for example, downtown San Diego averages January lows of 50 °F (10 °C) and August highs of 78 °F (26 °C). The city of El Cajon, just 10 miles (16 km) inland from downtown San Diego, averages January lows of 42 °F (6 °C) and August highs of 88 °F (31 °C).
A sign of global warming, scientists at Scripps Institution of Oceanography say the average surface temperature of the water at Scripps Pier in the California Current has increased by almost 3 degrees since 1950.
Annual rainfall along the coast averages 10.65 inches (271 mm) and the median is 9.6 inches (240 mm). The months of December through March supply most of the rain, with February the only month averaging 2 inches (51 mm) or more. The months of May through September tend to be almost completely dry. Although there are few wet days per month during the rainy period, rainfall can be heavy when it does fall. Rainfall is usually greater in the higher elevations of San Diego; some of the higher areas can receive 11–15 inches (280–380 mm) per year. Variability from year to year can be dramatic: in the wettest years of 1883/1884 and 1940/1941 more than 24 inches (610 mm) fell, whilst in the driest years as little as 3.2 inches (80 mm). The wettest month on record is December 1921 with 9.21 inches (234 mm).
Snow in the city is so rare that it has been observed only five times in the century-and-a-half that records have been kept. In 1949 and 1967, snow stayed on the ground for a few hours in higher locations like Point Loma and La Jolla. The other three occasions, in 1882, 1946, and 1987, involved flurries but no accumulation.

Like most of southern California, the majority of San Diego's current area was originally occupied by chaparral, a plant community made up mostly of drought-resistant shrubs. The endangered Torrey pine has the bulk of its population in San Diego in a stretch of protected chaparral along the coast. The steep and varied topography and proximity to the ocean create a number of different habitats within the city limits, including tidal marsh and canyons. The chaparral and coastal sage scrub habitats in low elevations along the coast are prone to wildfire, and the rates of fire have increased in the 20th century, due primarily to fires starting near the borders of urban and wild areas.
San Diego's broad city limits encompass a number of large nature preserves, including Torrey Pines State Reserve, Los Peñasquitos Canyon Preserve, and Mission Trails Regional Park. Torrey Pines State Reserve and a coastal strip continuing to the north constitute the only location where the rare species of Torrey Pine, P. torreyana torreyana, is found.
Due to the steep topography that prevents or discourages building, along with some efforts for preservation, there are also a large number of canyons within the city limits that serve as nature preserves, including Switzer Canyon, Tecolote Canyon Natural Park, and Marian Bear Memorial Park in the San Clemente Canyon, as well as a number of small parks and preserves.
San Diego County has one of the highest counts of animal and plant species that appear on the endangered list of counties in the United States. Because of its diversity of habitat and its position on the Pacific Flyway, San Diego County has recorded 492 different bird species, more than any other region in the country. San Diego always scores highly in the number of bird species observed in the annual Christmas Bird Count, sponsored by the Audubon Society, and it is known as one of the "birdiest" areas in the United States.
San Diego and its backcountry suffer from periodic wildfires. In October 2003, San Diego was the site of the Cedar Fire, called the largest wildfire in California over the past century. The fire burned 280,000 acres (1,100 km2), killed 15 people, and destroyed more than 2,200 homes. In addition to damage caused by the fire, smoke resulted in a significant increase in emergency room visits due to asthma, respiratory problems, eye irritation, and smoke inhalation; the poor air quality caused San Diego County schools to close for a week. Wildfires four years later destroyed some areas, particularly within the communities of Rancho Bernardo, Rancho Santa Fe, and Ramona.

San Diego was named the ninth-most LGBT-friendly city in the U.S. in 2013. The city also has the seventh-highest population of gay residents in the U.S. Additionally in 2013, San Diego State University (SDSU), one of the city's prominent universities, was named one of the top LGBT-friendly campuses in the nation.
According to a 2014 study by the Pew Research Center, 68% of the population of the city identified themselves as Christians, with 32% professing attendance at a variety of churches that could be considered Protestant, and 32% professing Roman Catholic beliefs. while 27% claim no religious affiliation. The same study says that other religions (including Judaism, Buddhism, Islam, and Hinduism) collectively make up about 5% of the population.
Many popular museums, such as the San Diego Museum of Art, the San Diego Natural History Museum, the San Diego Museum of Man, the Museum of Photographic Arts, and the San Diego Air & Space Museum are located in Balboa Park, which is also the location of the San Diego Zoo. The Museum of Contemporary Art San Diego (MCASD) is located in La Jolla and has a branch located at the Santa Fe Depot downtown. The downtown branch consists of two building on two opposite streets. The Columbia district downtown is home to historic ship exhibits belonging to the San Diego Maritime Museum, headlined by the Star of India, as well as the unrelated San Diego Aircraft Carrier Museum featuring the USS Midway aircraft carrier.

The largest sectors of San Diego's economy are defense/military, tourism, international trade, and research/manufacturing. In 2014, San Diego was designated by a Forbes columnist as the best city in the country to launch a small business or startup company. San Diego recorded a median household income of $79,646 in 2018, an increase of 3.89% from $76,662 in 2017. The median property value in San Diego in 2018 was $654,700, and the average home has two cars per household.
Defense and military
The economy of San Diego is influenced by its deepwater port, which includes the only major submarine and shipbuilding yards on the West Coast. Several major national defense contractors were started and are headquartered in San Diego, including General Atomics, Cubic, and NASSCO.
San Diego hosts the largest naval fleet in the world: In 2008 it was home to 53 ships, over 120 tenant commands, and more than 35,000 sailors, marines, Department of Defense civilian employees and contractors. About 5 percent of all civilian jobs in the county are military-related, and 15,000 businesses in San Diego County rely on Department of Defense contracts.
Military bases in San Diego include US Navy facilities, Marine Corps bases, and Coast Guard stations. The city is "home to the majority of the U.S. Pacific Fleet's surface combatants, all of the Navy's West Coast amphibious ships and a variety of Coast Guard and Military Sealift Command vessels".
The military infrastructure in San Diego is still growing and developing, with numerous military personnel stationed there, numbers of which are expected to rise. This plays a significant role in the city's economy, as of 2020, it provides roughly 25% of the GRP and provides 23% of the total jobs in San Diego.
Tourism is a major industry owing to the city's climate, beaches, and tourist attractions such as Balboa Park, Belmont amusement park, San Diego Zoo, San Diego Zoo Safari Park, and SeaWorld San Diego. San Diego's Spanish and Mexican heritage is reflected in many historic sites across the city, such as Mission San Diego de Alcalá and Old Town San Diego State Historic Park. Also, the local craft brewing industry attracts an increasing number of visitors for "beer tours" and the annual San Diego Beer Week in November; San Diego has been called "America's Craft Beer Capital."
San Diego County hosted more than 32 million visitors in 2012; collectively they spent an estimated $8 billion. The visitor industry provides employment for more than 160,000 people.
San Diego's cruise ship industry used to be the second-largest in California. Numerous cruise lines operate out of San Diego. However, cruise ship business has been in decline since 2008, when the Port hosted over 250 ship calls and more than 900,000 passengers. By 2016–2017, the number of ship calls had fallen to 90.
Local sightseeing cruises are offered in San Diego Bay and Mission Bay, as well as whale-watching cruises to observe the migration of gray whales, peaking in mid-January. Sport fishing is another popular tourist attraction; San Diego is home to southern California's biggest sport fishing fleet.
San Diego's commercial port and its location on the United States–Mexico border make international trade an important factor in the city's economy. The city is authorized by the United States government to operate as a Foreign Trade Zone.
The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third-highest volume of trucks and dollar value of trade among all United States-Mexico land crossings.
One of the Port of San Diego's two cargo facilities is located in Downtown San Diego at the Tenth Avenue Marine Terminal. This terminal has facilities for containers, bulk cargo, and refrigerated and frozen storage, so that it can handle the import and export of many commodities. In 2009 the Port of San Diego handled 1,137,054 short tons of total trade; foreign trade accounted for 956,637 short tons while domestic trade amounted to 180,417 short tons.
Historically tuna fishing and canning was one of San Diego's major industries, although the American tuna fishing fleet is no longer based in San Diego. Seafood company Bumble Bee Foods is headquartered in San Diego and Chicken of the Sea was until 2018.
San Diego hosts several major producers of wireless cellular technology. Qualcomm was founded and is headquartered in San Diego, and is one of the largest private-sector employers in San Diego. Other wireless industry manufacturers headquartered here include Nokia, LG Electronics, Kyocera International, Cricket Communications and Novatel Wireless. San Diego also has the U.S. headquarters for the Slovakian security company ESET. San Diego has been designated as an iHub Innovation Center for potential collaboration between wireless and the life sciences.
The University of California, San Diego and other research institutions have helped to fuel the growth of biotechnology. In 2013, San Diego had the second-largest biotech cluster in the United States, below the Boston area and above the San Francisco Bay Area. There are more than 400 biotechnology companies in the area. In particular, the La Jolla and nearby Sorrento Valley areas are home to offices and research facilities for numerous biotechnology companies. Major biotechnology companies like Illumina and Neurocrine Biosciences are headquartered in San Diego, while many other biotech and pharmaceutical companies have offices or research facilities in San Diego. San Diego is also home to more than 140 contract research organizations (CROs) that provide contract services for pharmaceutical and biotechnology companies.
According to the city's 2021 Annual Comprehensive Financial Report, the top employers in the city are:
|Naval Base San Diego||43,003|
|University of California, San Diego||35,807|
|County of San Diego||17,285|
|San Diego Unified School District||13,559|
|City of San Diego||11,295|
|Northrop Grumman Corporation||5,652|
San Diego has high real estate prices. San Diego home prices peaked in 2005, and then declined along with the national trend. As of December 2010, prices were down 36 percent from the peak, median price of homes having declined by more than $200,000 between 2005 and 2010. As of May 2015, the median price of a house was $520,000. In November 2018 the median home price was $558,000. The San Diego metropolitan area had one of the worst housing affordability rankings of all metropolitan areas in the United States in 2009.
Consequently, San Diego has experienced negative net migration since 2004. A significant number of people moved to adjacent Riverside County, commuting daily to jobs in San Diego, while others are leaving the region altogether and moving to more affordable regions.
San Diego is currently home to one major professional sports team and several other highest-level professional teams, as well as minor league teams, semi-pro and amateur teams, and college athletics teams, in addition to individual and other sporting events.

Primary and secondary schools
Public schools in San Diego are operated by independent school districts. The majority of the public schools in the city are served by the San Diego Unified School District, the second-largest school district in California, which includes 11 K–8 schools, 107 elementary schools, 24 middle schools, 13 atypical and alternative schools, 28 high schools, and 45 charter schools.
Several adjacent school districts which are headquartered outside the city limits serve some schools within the city; these include the Poway Unified School District, Del Mar Union School District, San Dieguito Union High School District, and Sweetwater Union High School District. In addition, there are a number of private schools in the city.
Colleges and universities
According to education rankings released by the U.S. Census Bureau in 2017, 44.4% of San Diegans (city, not county) ages 25 and older hold bachelor's degrees, compared to 30.9% in the United States as a whole. The census ranks the city as the ninth-most educated city in the United States, based on these figures.
The largest university in the area is the University of California, San Diego (UCSD). The university is the southernmost campus of the University of California system and is the second largest employer in the city. It is the only university in the city that is classified "R1: Doctoral Universities – Very high research activity", and it has the 7th largest research expenditure in the country.
Other public colleges and universities in the city include San Diego State University (SDSU) and the San Diego Community College District, which includes San Diego City College, San Diego Mesa College, and San Diego Miramar College.
Private non-profit colleges and universities in the city include the University of San Diego (USD), Point Loma Nazarene University (PLNU), National University's San Diego campus, University of Redlands' School of Business San Diego campus, Brandman University's San Diego campus, San Diego Christian College, and John Paul the Great Catholic University. For-profit institutions include Alliant International University (AIU), California International Business University (CIBU), California College San Diego, Fashion Institute of Design & Merchandising's San Diego campus, NewSchool of Architecture and Design, Platt College, Southern States University (SSU), UEI College, and Woodbury University School of Architecture's satellite campus.
There is one medical school in the city, the UCSD School of Medicine. There are three ABA accredited law schools in the city, which include California Western School of Law, Thomas Jefferson School of Law, and University of San Diego School of Law. There is also one law school, Western Sierra Law School, not accredited by the ABA.
The city-run San Diego Public Library system is headquartered downtown and has 36 branches throughout the city. The newest location is in Skyline Hills, which broke ground in 2015. The libraries have had reduced operating hours since 2003 due to the city's financial problems. In 2006 the city increased spending on libraries by $2.1 million. A new nine-story Central Library on Park Boulevard at J Street opened on September 30, 2013.
In addition to the municipal public library system, there are nearly two dozen libraries open to the public run by other governmental agencies, and by schools, colleges, and universities. Noteworthy are the Malcolm A. Love Library at San Diego State University, and the Geisel Library at the University of California, San Diego.
Water is supplied to residents by the Water Department of the City of San Diego. The city receives most of its water from the Metropolitan Water District of Southern California.
Gas and electric utilities are provided by San Diego Gas & Electric, a division of Sempra Energy.
In the mid-20th century the city had mercury vapor street lamps. In 1978, the city decided to replace them with more efficient sodium vapor lamps. This triggered an outcry from astronomers at Palomar Observatory 60 miles (100 km) north of the city, concerned that the new lamps would increase light pollution and hinder astronomical observation. The city altered its lighting regulations to limit light pollution within 30 miles (50 km) of Palomar.
In 2011, the city announced plans to upgrade 80% of its street lighting to new energy-efficient lights that use induction technology, a modified form of fluorescent lamp producing a broader spectrum than sodium vapor lamps. The new system is predicted to save $2.2 million per year in energy and maintenance. The city stated the changes would "make our neighborhoods safer." They also increase light pollution.
In 2014, San Diego announced plans to become the first U.S. city to install cyber-controlled street lighting, using an "intelligent" lighting system to control 3,000 LED street lights.
With the automobile being the primary means of transportation for over 80 percent of residents, San Diego is served by a network of freeways and highways. This includes Interstate 5, which runs south to Tijuana and north to Los Angeles; Interstate 8, which runs east to Imperial County and the Arizona Sun Corridor; Interstate 15, which runs northeast through the Inland Empire to Las Vegas and Salt Lake City; and Interstate 805, which splits from I-5 near the Mexican border and rejoins I-5 at Sorrento Valley.
Major state highways include SR 94, which connects downtown with I-805, I-15 and East County; SR 163, which connects downtown with the northeast part of the city, intersects I-805 and merges with I-15 at Miramar; SR 52, which connects La Jolla with East County through Santee and SR 125; SR 56, which connects I-5 with I-15 through Carmel Valley and Rancho Peñasquitos; SR 75, which spans San Diego Bay as the San Diego-Coronado Bridge, and also passes through South San Diego as Palm Avenue; and SR 905, which connects I-5 and I-805 to the Otay Mesa Port of Entry.
The stretch of SR 163 that passes through Balboa Park is San Diego's oldest freeway, and has been called one of America's most beautiful parkways.
San Diego's roadway system provides an extensive network of cycle routes. Its dry and mild climate makes cycling a convenient year-round option; however, the city's hilly terrain and long average trip distances make cycling less practicable. Older and denser neighborhoods around the downtown tend to be oriented to utility cycling. This is partly because of the grid street patterns now absent in newer developments farther from the urban core, where suburban style arterial roads are much more common. As a result, the majority of cycling is recreational. In 2006, San Diego was rated the best city (with a population over 1 million) for cycling in the U.S.
San Diego is served by the San Diego Trolley light rail system, by the SDMTS bus system, private jitneys in some neighborhoods, and by Coaster and Amtrak Pacific Surfliner commuter rail; northern San Diego county is also served by the Sprinter light rail line. The trolley primarily serves downtown and surrounding urban communities, Mission Valley, east county, and coastal south bay. A mid-coast extension of the Trolley operates from Old Town to University City and the University of California, San Diego along the I-5 Freeway since November 2021. The Amtrak and Coaster trains currently run along the coastline and connect San Diego with Los Angeles, Orange County, Riverside, San Bernardino, and Ventura via Metrolink and the Pacific Surfliner. There are two Amtrak stations in San Diego, in Old Town and the Santa Fe Depot downtown. San Diego transit information about public transportation and commuting is available on the Web and by dialing "511" from any phone in the area.
The city has two major commercial airports within or near its city limits. Downtown San Diego International Airport (SAN), also known as Lindbergh Field, is the busiest single-runway airport in the United States. It served over 24 million passengers in 2018, and is dealing with larger numbers every year. It is located on San Diego Bay, three miles (4.8 km) from downtown, and maintains scheduled flights to the rest of the United States (including Hawaii), as well as to Canada, Germany, Mexico, Japan, and the United Kingdom. It is operated by an independent agency, the San Diego Regional Airport Authority. Tijuana International Airport has a terminal within the city limits in the Otay Mesa district connected to the rest of the airport in Tijuana, Mexico, via the Cross Border Xpress cross-border footbridge. It is the primary airport for flights to the rest of Mexico, and offers connections via Mexico City to the rest of Latin America. In addition, the city has two general-aviation airports, Montgomery Field (MYF) and Brown Field (SDM).
Recent regional transportation projects have sought to mitigate congestion, including improvements to local freeways, expansion of San Diego Airport, and doubling the capacity of the cruise ship terminal. Freeway projects included expansion of Interstates 5 and 805 around "The Merge" where these two freeways meet, as well as expansion of Interstate 15 through North County, which includes new high-occupancy-vehicle (HOV) "managed lanes". A tollway (the southern portion of SR 125, known as the South Bay Expressway) connects SR 54 and Otay Mesa, near the Mexican border. According to an assessment in 2007, 37 percent of city streets were in acceptable condition. However, the proposed budget fell $84.6 million short of bringing streets up to an acceptable level. Expansion at the port has included a second cruise terminal on Broadway Pier, opened in 2010. Airport projects include expansion of Terminal Two.
