San Diego County, officially the County of San Diego, is a county in the southwestern corner of the state of California, in the United States. As of the 2010 census, the population was 3,095,313,[5] making it California's second-most populous county and the fifth-most populous in the United States. Its county seat is San Diego,[8] the second-most populous city in California and the eighth-most populous city in the United States. It is the southwesternmost county in the 48 contiguous United States, and is a border county.

San Diego County comprises the San Diego-Chula Vista-Carlsbad, CA Metropolitan Statistical Area,[9] which is the 17th most populous metropolitan statistical area and the 18th most populous primary statistical area of the United States as of July 1, 2012.[10][11] San Diego County is also part of the San Diego–Tijuana transborder metropolitan area, the largest metropolitan area shared between the United States and Mexico.

San Diego County has more than 70. miles (112.7 km) of coastline. This forms the most densely populated region of the county, which has a mild Mediterranean to semiarid climate and extensive chaparral vegetation, similar to the rest of the western portion of southern California. Precipitation and temperature extremes increase to the east, with mountains that receive frost and snow in the winter.[12] These lushly forested mountains receive more rainfall than average in southern California, while the desert region of the county lies in a rain shadow to the east, which extends into the Desert Southwest region of North America.

There are 16 military installations, of the U.S. Navy, U.S. Marine Corps, and the U.S. Coast Guard in San Diego County. These include Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, Naval Air Station North Island, and Coast Guard Air Station San Diego.

San Diego County is home to 18 Native American tribal reservations, the most of any county in the United States.

From north to south, San Diego County extends from the southern borders of Orange and Riverside Counties to the Mexico-U.S. border and the Baja California municipalities of Tijuana and Tecate. From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County, which separated from it in 1907.


The area which is now San Diego County has been inhabited for more than 12,000 years by Kumeyaay (also called Diegueno and Ipai/Tipai), Payómkawichum (Luiseño), Kuupangaxwichem (Cupeño), ʔívil̃uqaletem (Cahuilla), and the Acjachemen (Juaneño) Indians and their local predecessors.[13]

In 1542, the explorer Juan Rodríguez Cabrillo, who may have been born in Portugal but sailed on behalf of Spain, claimed San Diego Bay for the Spanish Empire, and he named the site San Miguel.[14] In November 1602, Sebastián Vizcaíno surveyed the harbor and what are now Mission Bay and Point Loma and named the area for Saint Didacus, a Spaniard more commonly known as San Diego.[15] European settlement in what is now San Diego County began with the founding of the San Diego Presidio and Mission San Diego de Alcalá by Spanish soldiers and clerics in 1769.[16] This county was part of Alta California under the Viceroyalty of New Spain until the Mexican declaration of independence. From 1821 through 1848 this area was part of Mexico.

San Diego County became part of the United States as a result of the Treaty of Guadalupe Hidalgo in 1848, ending the Mexican–American War. This treaty designated the new border as terminating at a point on the Pacific Ocean coast which would result in the border passing one Spanish league south of the southernmost portion of San Diego Bay, thus ensuring that the United States received all of this natural harbor.

San Diego County was one of the original counties of California, created at the time of California statehood in 1850.[17]:221

At the time of its establishment in 1850, San Diego County was relatively large, and included all of southernmost California south and east of Los Angeles County. It included areas of what are now Inyo and San Bernardino Counties, as well as all of what are now Riverside and Imperial Counties.[17]:221

During the later part of the 19th century, there were numerous changes in the boundaries of San Diego County, when various areas were separated to make up the counties mentioned above. The most recent changes were the establishments of Riverside County in 1893[17]:207 and Imperial County in 1907.[17]:113 Imperial County was also the last county to be established in California, and after this division, San Diego no longer extended from the Pacific Ocean to the Colorado River, and it no longer covered the entire border between California and Mexico.

According to the U.S. Census Bureau, the county has an area of 4,526 square miles (11,720 km2), of which 4,207 square miles (10,900 km2) is land and 319 square miles (830 km2) (7.0%) is water.[18] The county is larger in area than the combined states of Rhode Island and Delaware.[19]

San Diego County has a varied topography. On its western side is more than 70. miles (112.7 km) of coastline.[20] Most of San Diego between the coast and the Laguna Mountains consists of hills, mesas, and small canyons. Snow-capped (in winter) mountains rise to the east, with the Sonoran Desert farther to the east. Cleveland National Forest is spread across the central portion of the county, while the Anza-Borrego Desert State Park occupies most of the northeast.

Although the county's western third is primarily urban, the mountains and deserts in the eastern two-thirds are primarily undeveloped backcountry. Most of these backcountry areas are home to a native plant community known as chaparral. San Diego County contains more than 1,000,000 acres (4,000 km2) of chaparral, twice as much as any other California county.[21]

North San Diego County is known as North County; the exact geographic definitions of "North County" vary, but it includes the northern suburbs and sometimes certain northern neighborhoods of the City of San Diego.

The eastern suburbs are collectively known as East County, though most still lie in the western third of the county. The southern suburbs and southern detached portion of the city of San Diego, extending to the Mexican border, are collectively referred to as South Bay.

Periodically the area has been subject to wildfires that force thousands to evacuate. The most recent are the December 2017 Lilac Fire and the May 2014 San Diego County wildfires; before them was the Witch Creek Fire in 2007 and the Cedar Fire in 2003. California defines a fire season in which fires are most likely to occur, usually between late July and late October (which are the driest months of the area). Signs posted in numerous spots of the county provide information on the level of threats from fires based on weather conditions.


Cleveland National Forest

Under the Köppen climate classification system, the urban and suburban San Diego area straddles areas of Mediterranean climate (CSa) to the north and semi-arid climate (BSh) to the south and east.[22] As a result, it is often described as "arid Mediterranean" and "semi-arid steppe." Farther east, arid desert conditions prevail. Western San Diego's climate is characterized by warm, dry summers and mild winters with most of the annual precipitation falling between November and March. The city has mild, mostly dry weather, with an average of 201 days above 70 °F (21 °C) and low rainfall (9–13 inches (23–33 cm) annually). Summer temperatures are generally warm, with average highs of 70–78 °F (21–26 °C) and lows of 55–66 °F (13–19 °C). Temperatures exceed 90 °F (32 °C) only four days a year. Most rainfall occurs from November to April. Winter temperatures are mild, with average high temperatures of 66–70 °F (19–21 °C) and lows of 50–56 °F (10–13 °C).

The climate in the San Diego area, like much of California, often varies significantly over short geographical distances resulting in microclimates. In San Diego's case this is mainly due to 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 will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 5–10 miles (8.0–16 km) inland. This happens every year in May and June.[23] Even in the absence of June gloom, inland areas tend to 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 48 °F (9 °C) and August highs of 77 °F (25 °C).[24] The city of El Cajon, just 10 miles (16 km) northeast of downtown San Diego, averages January lows of 42 °F (6 °C) and August highs of 89 °F (32 °C).[25] Julian, in the mountains, has an average January low of 29 °F (−2 °C) and August high of 85 °F (29 °C).[26] Borrego Springs, in the Colorado Desert, has an average January low of 43 °F (6 °C) and August high of 106 °F (41 °C).[27]

Rainfall along the coast averages about 10 inches (25 cm) of precipitation annually, which occurs mainly during the cooler months of December through April. Though there are few wet days per month during the rainy period, rainfall can be heavy when it does occur. However, the rainfall is greater in the higher elevations of San Diego. Some of the higher areas of San Diego, such as Palomar Mountain and the Laguna Mountains, receive 20–40 inches (51–100 cm) of rain per year, supporting lush forests similar to the Sierra Nevada and California Coast Range. The Colorado Desert portion of the county lies to the east of the mountains, which receives the least amount of precipitation; Borrego Springs, the largest population center in the desert, averages only 5 inches (13 cm), with a high evaporation rate.

Males had a median income of $36,952 versus $30,356 for females. The per capita income for the county was $22,926. About 8.9% of families and 12.4% of the population were below the poverty line, including 16.5% of those under age 18 and 6.8% of those age 65 or over.

Much of the county's high-income residents are concentrated in the northern part of the city of San Diego. The San Diego metropolitan area has two places with both a population of over 50,000 and a per capita income of over $40,000: Carlsbad and Encinitas.

The county's largest continuous high-income urban area is a triangle from a first point on the northern edge of Carlsbad, a second point southeast of Escondido, and a third point on the southern edge of La Jolla. It contains all or most of the cities of Carlsbad, Encinitas, Solana Beach, Del Mar, and Poway in addition to a substantial portion of northern San Diego.[62]


According to a Point-In-Time count taken for the San Diego Regional Task Force on the Homeless, there were 8,576 homeless individuals on January 6, 2018, a 6% decrease from 2017. 3,586 were sheltered, and 4,990 were not. 4,912 (75.3%) were in the City of San Diego. North County Inland had 1,153 (13.4%), North County Coastal with 822 homeless (9.6%), 602 (7%) were found in South County, and 1,087 (12.7%) in East County.[63]


According to the Pew Research Center as of 2014, 68% of adults in the county are Christian, of whom 32% are Catholic. 27% were unaffiliated, and 5% adhered to a Non-Christian faith.[64] According to the University of Southern California, in 2010, the largest faith in the county was Catholicism, followed by Nondenominational Christians, and Mormons.[65]

In 2014, the county had 978 religious organizations, the seventh most out of all US counties.[66]

Immigration Data

In 2014 according to Pew Research Center, there are about 170,000 illegal aliens living in the region.[67] San Diego has been a destination for trafficked minors from Mexico and the Philippines.[68] In 2018, the United States Border Patrol caught an average of over a hundred individuals crossing the border illegally each day.[69]


San Diego County and Imperial County are part of the Southern Border Region, one of nine such regions. As a regional economy, the Southern Border Region is the smallest but most economically diverse region in the state. However, the two counties maintain weak relations and have little in common aside from their common border.[70] The region has a high cost of living.[71] This includes the highest cost of water in the United States.[72] As of 2018, San Diego County is within the top ten highest cost of rent in the United States;[73] this has led to people moving out of the county.[74]


San Diego County's agriculture industry was worth $1.85 billion in 2013,[75] and is one of the top five egg producing counties in the United States.[76] In 2013, San Diego County also had the most small farms of any county in the United States, and had the 19th largest agricultural economy of any county in the United States.[77] According to the San Diego Farm Bureau, San Diego County is the United States' leading producer of avocados and nursery crops.[78] Until the early 20th century, San Diego County had a thriving wine industry; however the 1916 Charles Hatfield flood was the beginning of the end of the industry which included the destruction of the Daneri winery in Otay Valley.[79] As of October 2016, there are roughly one hundred vineyards and wineries in San Diego County.[80]


The county has been called "the Craft Beer Capital of America".[81] Brewing has been one of the fastest-growing business sectors with local breweries ranking among the 50 largest craft brewers in the United States and breweries that are consistently rated among the top breweries in the world.


Commercial operations to grow, test, or sell cannabis are not allowed in the unincorporated areas of the county. Companies must be licensed by the local agency to operate and each city or county may authorize none or only some of these activities. Local governments may not prohibit adults, who are in compliance with state laws, from growing, using, or transporting marijuana for personal use.[82]

Tourism plays a large part in the economics of the San Diego metropolitan area. Tourists are drawn to the region for a well rounded experience, everything from shopping to surfing as well as its mild climate. Its numerous tourist destinations include Westfield UTC, Seaport Village, Westfield Mission Valley and Fashion Valley Mall for shopping. SeaWorld San Diego and Legoland California as amusement parks. Golf courses such as Torrey Pines Golf Course and Balboa Park Golf Course. Museums such as the San Diego Museum of Man, San Diego Museum of Art, Reuben H. Fleet Science Center, San Diego Natural History Museum, USS Midway Museum, and the San Diego Air and Space Museum. Historical places such as the Gaslamp Quarter, Balboa Park and Old Town San Diego State Historic Park. Wildlife refuges, zoos, and aquariums such as the Birch Aquarium at Scripps, San Diego Zoo's Safari Park, San Diego Zoo and San Diego-La Jolla Underwater Park. Outdoor destinations include the Peninsular Ranges for hiking, biking, mountainboarding and trail riding. Surfing locations include Swami's, Stone Steps Beach, Torrey Pines State Beach, Cardiff State Beach, San Onofre State Beach and the southern portion of Black's Beach.

The region is host to the second largest cruise ship industry in California which generates an estimated $2 million annually from purchases of food, fuel, supplies, and maintenance services.[83] In 2008 the Port of San Diego hosted 252 ship calls and more than 800,000 passengers.[84]


The culture of San Diego is influenced heavily by American and Mexican cultures due to its position as a border town, its large Hispanic population, and its history as part of Spanish America and Mexico. The area's longtime association with the U.S. military also contributes to its culture. Present-day culture includes many historical and tourist attractions, a thriving musical and theatrical scene, numerous notable special events, a varied cuisine, and a reputation as one of America's premier centers of craft brewing.

San Diego County Administration Center

The Government of San Diego County is defined and authorized under the California Constitution, California law, and the Charter of the County of San Diego.[85] Much of the Government of California is in practice the responsibility of county governments such as the Government of San Diego County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, and social services. In addition the County serves as the local government for all unincorporated areas.[86] Some chartered cities such as San Diego and Chula Vista provide municipal services such as police, public safety, libraries, parks and recreation, and zoning. Other cities such as Del Mar and Vista arrange to have the County provide some or all of these services on a contract basis.

The county government is composed of the elected five-member Board of Supervisors, several other elected offices and officers

Office Official Party
Clerk Ernest J. Dronenburg Jr. Republican
District Attorney Summer Stephan Republican
Sheriff William Gore Republican
Treasurer Dan McAllister Republican

and numerous county departments and entities under the supervision of the Chief Administrative Officer such as the Probation Department. In addition, several entities of the government of California have jurisdiction conterminous with San Diego County, such as the San Diego Superior Court.

Under its foundational Charter, the five-member elected San Diego County Board of Supervisors is the county legislature. The board operates in a legislative, executive, and quasi-judicial capacity. As a legislative authority, it can pass ordinances for the unincorporated areas (ordinances that affect the whole county, like posting of restaurant ratings, must be ratified by the individual city). As an executive body, it can tell the county departments what to do, and how to do it. As a quasi-judicial body, the Board is the final venue of appeal in the local planning process.

As of January 2021, the members of the San Diego County Board of Supervisors are:[87]

District Supervisor Party
1 Nora Vargas (Vice Chair) Democrat
2 Joel Anderson Republican
3 Terra Lawson-Remer Democrat
4 Nathan Fletcher (Chair) Democrat
5 Jim Desmond Republican

For several decades, ending in 2013, all five supervisors were Republican, white, graduates of San Diego State University, and had been in office since 1995 or earlier. The Board was criticized for this homogeneity, which was made possible because supervisors draw their own district lines and are not subject to term limits.[88] (In 2010 voters put term limits in place, but they only apply going forward, so that each incumbent supervisor can serve an additional two terms before being termed out.[89]) That pattern was broken in 2013 when Slater-Price retired; she was replaced by Democrat Dave Roberts, who won election to the seat in November 2012 and was inaugurated in January 2013.[90]

The San Diego County Code is the codified law of San Diego County in the form of ordinances passed by the Board of Supervisors. The Administrative Code establishes the powers and duties of all officers and the procedures and rules of operation of all departments.

The county motto is "The noblest motive is the public good." County government offices are housed in the historic County Administration Center Building, constructed in 1935–1938 with funding from the Works Progress Administration.[91]

San Diego County had historically been a Republican stronghold. The Republican presidential nominee carried the county in every presidential election from 1948 through 2004, except in 1992 when Bill Clinton won a plurality. In 2008, Barack Obama became the first Democratic presidential candidate to win a majority of votes in San Diego County since World War II; he won a majority of county votes again in 2012. In 2020, the county voted in favor of the Democratic presidential nominee Joe Biden by 22.8%, the largest margin for a Democrat since 1936.

The city of San Diego itself is more Democratic than the county's average and has voted for Democrats in each presidential election since 1992. Various cities within the county are swing areas that have split their votes in elections since 2000. Republican strength is concentrated in North County, East County and the eastern backlands. Coronado has also traditionally been a Republican stronghold.

One unique feature of the political scene is the use of Golden Hall, a convention facility next to San Diego's City Hall, as "Election Central." The County Registrar of Voters rents the hall to distribute election results. Supporters and political observers gather to watch the results come in; supporters of the various candidates parade around the hall, carrying signs and chanting; candidates give their victory and concession speeches and host parties for campaign volunteers and donors at the site; and television stations broadcast live from the floor of the convention center.[95] The atmosphere at Election Central on the evening of election day has been compared to the voting portion of a political party national convention.[96]

On November 4, 2008, San Diego County voted 53.71% for Proposition 8 which amended the California Constitution to ban same-sex marriages, thus restoring Proposition 22 which was overturned by a ruling from the California Supreme Court. However the city of San Diego, along with the North County coastal cities of Del Mar, Encinitas, and Solana Beach, voted against Proposition 8. La Mesa was a virtual tie for Prop 8 support, while Carlsbad supported the referendum by only a 2% margin.[97]

San Diego County is primarily served by media in San Diego, including TV and radio stations based in the city.


San Diego County is served by many newspapers. The major regional paper is The San Diego Union-Tribune, also known as U-T San Diego, is ranked 23rd in the country (by daily circulation) as of March 2013.[108] The Union-Tribune serves both San Diego County and neighboring Imperial County. The former North County Times, based in Escondido and serving portions of Riverside County and North County, was purchased by the Union-Tribune in 2012 and closed down. For about a year after absorbing the North County Times the Union-Tribune published a North County edition,[109] but the regional edition was later abandoned.[110] The Los Angeles Times is also delivered in portions of the county. Many of the area's cities, towns and neighborhoods have their own local newspapers; the Union Tribune bought eight local weeklies in 2013 and is continuing to publish them as independent local newspapers.[110] The San Diego Daily Transcript reports business and legal news. Privately published papers like the Military Press Newspaper and the Navy Dispatch serve the military community both on and off base.

Other media

Potential future incorporations and past efforts

Some CDP's and other unincorporated communities of San Diego County have explored incorporating as independent cities/towns in the past, some of which have seen efforts culminate in ballot initiatives. Alpine, Fallbrook, Lakeside, Ramona, Rancho Santa Fe and Spring Valley have been tied to various incorporation studies, organized efforts and discussions in the past.[113] Voters in Fallbrook previously rejected incorporation in 1981 and 1987.[114] Rancho Santa Fe residents also rejected incorporation in 1987.[115] Among the existing cities of San Diego County, some had multiple failed incorporation efforts before ultimately succeeding in becoming a city. Lemon Grove, for example, saw incorporation measures fail in 1955, 1958 and 1964 before a successful incorporation vote in 1977.[116] Other cities have seen incorporation success thanks to mergers of neighboring unincorporated communities. Encinitas, for example, became a city through a combined effort between the then-unincorporated communities of Cardiff-by-the-Sea, Leucadia, New Encinitas, Old Encinitas and Olivenhain in 1986.[117] Encinitas and Solana Beach in 1986 remain the most recent examples of successful campaigns for cityhood within the County of San Diego.

Indian reservations

San Diego County has 18 federally recognized Indian reservations, more than any other county in the United States.[118] Although they are typical in size to other Indian reservations in California (many of which are termed "Rancherías"), they are relatively tiny by national standards, and all together total 200.2 sq mi (519 km2) of area.
