San Diego County is a county located in the southwestern corner of the state of California. As of the 2010 census, the population was 3,095,313. making it the second-most populous county in California and the fifth-most populous in the United States. Its county seat is San Diego, the eighth-most populous city in the United States. It is the south-westernmost county in the 48 contiguous United States.
San Diego County comprises the San Diego-Carlsbad, CA Metropolitan Statistical Area. It is also part of the San Diego–Tijuana metropolitan area, the largest metropolitan area shared between the United States and Mexico.
San Diego County has 70 miles (110 km) of coastline. Most of the county has a mild Mediterranean climate to semiarid climate, though there are mountains that receive frost and snow in the wintertime.
There are also 16 naval and military installations of the U.S. Navy, U.S. Marine Corps, and the U.S. Coast Guard in San Diego County. These include the Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, and Naval Air Station North Island.
Arising from an effort by the state government to identify regional economies, 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.
From north to south, San Diego County extends from the southern borders of Orange County and Riverside County to the Mexico–United States border and Baja California. From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County.

In 1542, the Portuguese-born explorer Juan Rodríguez Cabrillo, sailing for Spain, claimed San Diego Bay for the Spanish Empire, and he named the site San Miguel. 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. 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. 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 U.S.-Mexican 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, and it was created at the time of California statehood in 1850.:221
At the time of its establishment in 1850, San Diego County was relatively large, and included all of southernmost California which was south and east of Los Angeles County. As such it included areas of what are now Inyo County and San Bernardino County, as well as all of what is now Riverside County and Imperial County.:221
During the later part of the 19th century, there were numerous changes in the boundaries of San Diego County, when various areas became separated for the counties mentioned above. The most recent changes were the establishments of Riverside County in 1893:207 and Imperial County in 1907.: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 a total 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. The county is larger in area than the combined states of Rhode Island and Delaware.
San Diego County has a varied topography. On its western side is 70 miles (110 km) of coastline. 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 northeast, with the Sonoran Desert to the far 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 western third of the county is primarily urban, the mountains and deserts in the eastern two-thirds of the county consist primarily of undeveloped backcountry. Most of these backcountry areas are home to a native plant community known as chaparral. San Diego County contains more than a million acres (4,000 km²) of chaparral, twice as much as any other California county.
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 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 the months of late July and late October (which are the driest months of the area). Signs are posted in numerous spots of the county providing information on the level of threats from fires based on weather conditions.
Under the Köppen climate classification system, the San Diego area straddles areas of Mediterranean climate (CSa) to the north and semi-arid climate (BSh) to the south and east. As a result, it is often described as "arid Mediterranean" and "semi-arid steppe". 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 (8.0–16.1 km) inland. This happens every year in May and June. 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 50 °F (10 °C) and August highs of 78 °F (26 °C). 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 88 °F (31 °C).
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 fall. However, the rainfall is greater in the higher elevations of San Diego. Some of the higher areas of San Diego can receive 11–13 inches (28–33 cm) of rain a year.

Despite having a per capita income that ranks between the Los Angeles metropolitan area and the San Francisco Bay Area, San Diego County has relatively few places with a both a high population and levels of income significantly higher than its state and the United States. The San Diego metropolitan area only has two places with a both a population of over 50,000 per capita income of over $40,000: Carlsbad and Encinitas. In contrast, the Los Angeles metropolitan area has 10 and the San Francisco Bay Area has 12. (See California locations by income.) Even when controlling for population, the San Diego metropolitan area has unusually few large areas with high per capita incomes compared to the state's other two major metropolitan areas. This is because much of the county's high-income residents are concentrated in the northern part of the city of San Diego, which is reported as one unit for most demographic purposes.
The county's largest continuous high-income urban area has the appearance of a triangle constructed 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. The region is pictured to the right. 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.

Metropolitan Statistical Area
The United States Office of Management and Budget has designated San Diego County as the San Diego-Carlsbad, CA Metropolitan Statistical Area. The United States Census Bureau has ranked the San Diego-Carlsbad, CA Metropolitan Statistical Area as the 17th most populous metropolitan statistical area and the 18th most populous primary statistical area of the United States as of July 1, 2012. Greater San Diego ranks as the 38th largest metropolitan area in the Americas.
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. 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. 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 including the Sheriff, the District Attorney, Assessor/Recorder/County Clerk, and Treasurer/Tax Collector, 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 2013 the members of the San Diego County Board of Supervisors are:
- Greg Cox, District 1, Chairman
- Dianne Jacob, District 2
- Dave Roberts, District 3
- Ron Roberts, District 4 (no relation)
- Bill Horn, District 5
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. (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.) 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.
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 establishing 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.

San Diego County has 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.

The city of San Diego itself is more Democratic than the county's average and has voted for Democrats Clinton, Gore, Kerry, and Obama, respectively, in the last six presidential elections. In the 2004 presidential election, San Diego, Encinitas, National City, Del Mar, and some other areas voted for John Kerry; San Marcos, Escondido, Carlsbad, Oceanside, Coronado, Santee, Poway, El Cajon, and Vista overwhelmingly backed George W. Bush. Chula Vista, La Mesa, Lemon Grove, Solana Beach, and Imperial Beach are considered swing areas of the county – Chula Vista and Imperial Beach narrowly backed Al Gore in 2000 but narrowly voted for Bush in 2004, while Solana Beach switched from Bush in 2000 to Kerry in 2004. La Mesa narrowly voted for Bush both times, and Lemon Grove narrowly went Democratic both times. However, all of these swing areas as well as Oceanside voted for Obama in 2008.
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. The atmosphere at Election Central on the evening of election day has been compared to the voting portion of a political party national convention.
On Nov 4, 2008 San Diego County voted 53.8% 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 Del Mar, Encinitas, and Solana Beach, voted against Proposition 8.
