San Diego County is a large county located in the southwestern corner of the U.S. state of California. Hence, San Diego County is also located in the southwestern corner of the 48 contiguous United States. Its county seat and largest city is San Diego. Its population was about 2,813,835 in the 2000 U.S. Census. According to the 2010 U.S. Census, San Diego County had a population of 3,095,313 people, making it the second-most-populous county in California, just behind its northern neighbor Los Angeles County. Its population in 2009 was estimated at 3,208,466, making it the fifth most-populous county in the United States and giving it a population greater than 20 of the 50 U.S. states.
San Diego County has 70 miles (110 km) of coastline. It has a mild Mediterranean to semi-arid climate. Also in this county are 16 significant naval and military locations of the United States Navy, U.S. Marine Corps and the U.S. Coast Guard, including Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, and Naval Air Station North Island.
San Diego County defines the metropolitan statistical area of San Diego-Carlsbad-San Marcos, and in its metropolitan capacity is also known as Greater San Diego. In addition, San Diego County is part of the San Diego–Tijuana metropolitan area, an area with above five million people and the largest bi-national metropolitan area shared between the United States and Mexico. 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, though the two counties maintain weak relations and have little in common, aside from their border proximity.
San Diego County extends south all the way to the Mexican border, which is also the northern border of the State of Baja California and the northern municipal limits of Tijuana Municipality and Tecate Municipality. San Diego County is bordered by Orange County and Riverside County on its north, by Imperial County on its east, and the Pacific Ocean on its west and southwest.
European settlement in what is now San Diego County began with the founding of the Mission San Diego de Alcalá, by Spanish pioneers, in 1769. This county was part of Alta California under the Viceroyalty of New Spain until the Mexican revolution. 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. San Diego County was named for San Diego Bay, which had been rechristened in 1602 by Sebastián Vizcaíno in honor of the Franciscan St. Didacus of Alcalá, known in Spanish as San Diego de Alcalá de Henares, and whose name was borne by Vizcaíno's flagship.
As originally created in 1850 San Diego County was quite large, and it included all of southmost California that was south and east of Los Angeles County. As such it included major parts of what are now Inyo County and San Bernardino County, and all of Riverside County and Imperial County.
During the later part of the 19th century, there were numerous changes in the boundaries of San Diego County, when various areas were sliced off to form the newer counties mentioned above. The most recent changes were the creation of Riverside County in 1893 and Imperial County in 1907. Imperial County was the last new 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 2000 census, the county has a total area of 4,525.52 square miles (11,721.0 km2), of which 4,199.89 square miles (10,877.7 km2) (or 92.80%) is land and 325.62 square miles (843.4 km2) (or 7.20%) is water.
The county is bigger 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.

San Diego County has historically been a Republican stronghold: 2008 was the first time in decades that a Democratic presidential nominee won a majority of the county's votes (though in 1992 Bill Clinton won a plurality). The city of San Diego itself is more Democratic than the county's average (though fairly moderate for a large city) and has voted for Democrats Clinton, Gore, Kerry, and Obama in the last five presidential elections respectively. The city of San Diego, as well as Coronado and Imperial Beach, is part of the 53rd congressional district which has a Cook Partisan Voting Index (CPVI) of D +12. San Diego's northern and eastern suburbs tend to be very conservative. Northern suburbs including Carlsbad are part of the 50th district with a CPVI of R +5. 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. In 2008, Barack Obama became the first Democrat to win a majority of votes in San Diego County since World War II. Obama captured Chula Vista, Oceanside, and Carlsbad.
One unique feature of the political scene is the use of Golden Hall, a convention facility next to City Hall, as a central elections center. The County Registrar of Voters rents the hall to distribute election results. Supporters and political observers are invited to watch the results come in, candidates give their victory and concession speeches and host parties for campaign volunteers and donors at the site, and television stations broadcast from the floor of the convention center. Golden Hall was scheduled to be closed in 2004, but was reused again for the November 2005 special election. The atmosphere on the evening of election day is often comparable to the voting portion of a political party national convention.
In the House of Representatives, all of California's 50th, 52nd, and 53rd districts and parts of the 49th and 51st districts are in the county. By district, the seats are held by Republican Darrell Issa, Republican Brian Bilbray, Democrat Bob Filner, Republican Duncan D. Hunter, and Democrat Susan Davis.
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.
In the State Assembly, parts of the 66th and 73rd districts, and all of the 74th–79th districts are in the county. Assemblymembers are: District 66, Kevin Jeffries (R); District 73, Diane Harkey (R); District 74, Martin Garrick (R); District 75, Nathan Fletcher (R); District 76, Toni Atkins (D); District 77, Brian W. Jones (R); District 78, Marty Block (D); and District 79, Ben Hueso (D).
In the State Senate, all of the 38th and 39th district and parts of the 36th and 40th districts are in the county. Senators are: District 36, Joel Anderson (R); District 38, Mark Wyland (R); District 39, Christine Kehoe (D); and District 40 Juan Vargas (D).
