Los Angeles County is one of the original counties of California, created at the time of statehood in 1850.[12] The county originally included parts of what are now Kern, San Bernardino, Riverside, Inyo, Tulare, Ventura, and Orange counties. In 1851 and 1852, Los Angeles County stretched from the coast to the border of Nevada.[13] As the population increased, sections were split off to organize San Bernardino County in 1853, Kern County in 1866, and Orange County in 1889.

Prior to the 1870s, Los Angeles County was divided into townships, many of which were amalgamations of one or more old ranchos. They were:

According to the U.S. Census Bureau, the county has an area of 4,751 square miles (12,310 km2), of which 4,058 square miles (10,510 km2) is land and 693 square miles (1,790 km2) (15%) is water.[15] Los Angeles County borders 70 miles (110 km) of coast on the Pacific Ocean and encompasses mountain ranges, valleys, forests, islands, lakes, rivers, and desert. The Los Angeles River, Rio Hondo, the San Gabriel River and the Santa Clara River flow in Los Angeles County, while the primary mountain ranges are the Santa Monica Mountains and the San Gabriel Mountains. The western extent of the Mojave Desert begins in the Antelope Valley, in the northeastern part of the county.

Other population centers are found in the Santa Clarita Valley, Pomona Valley, Crescenta Valley and Antelope Valley.

The county is divided west-to-east by the San Gabriel Mountains, which are part of the Transverse Ranges of southern California, and are contained mostly within the Angeles National Forest. Most of the county's highest peaks are in the San Gabriel Mountains, including Mount San Antonio 10,068 feet (3,069 m)) at the Los Angeles-San Bernardino county lines, Mount Baden-Powell 9,399 feet (2,865 m), Mount Burnham 8,997 feet (2,742 m) and Mount Wilson 5,710 feet (1,740 m). Several lower mountains are in the northern, western, and southwestern parts of the county, including the San Emigdio Mountains, the southernmost part of Tehachapi Mountains and the Sierra Pelona Mountains.

Los Angeles County includes San Clemente Island and Santa Catalina Island, which are part of the Channel Islands archipelago off the Pacific Coast.

Law, government and politics

Los Angeles County Charter rev2016.pdf
Charter of the County of Los Angeles, with amendments through March 2002


The Government of Los Angeles County is defined and authorized under the California Constitution, California law and the Charter of the County of Los Angeles.[38] Much of the Government of California is in practice the responsibility of local governments such as the Government of Los Angeles County.

The county's voters elect a governing five-member Los Angeles County Board of Supervisors. The small size of the board means each supervisor represents over 2 million people. 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, and holds public hearings on various agenda items.

As of 2008, the Board of Supervisors oversees a $22.5 billion annual budget and approximately 100,000 employees.[39] The county government is managed on a day-to-day basis by a Chief Executive Officer and is organized into many departments, each of which is enormous in comparison to equivalent county-level (and even many state-level) departments anywhere else in the United States. Some of the larger or better-known departments include:

  • Los Angeles County Department of Consumer and Business Affairs – offers consumers in the county a variety of services including: consumer and real estate counseling, mediation, and small claims counseling investigates consumer complains, real estate fraud and identity theft issues. The department also provides small business certifications and helps entrepreneurs navigate the process of opening a business.
  • Los Angeles County Department of Children and Family Services – administers foster care
  • Los Angeles County Fire Department – provides firefighting services for the unincorporated parts of Los Angeles County, as well as 58 cities.
  • Los Angeles County Department of Health Services – operates several county hospitals and a network of primary care clinics,
  • Los Angeles County Department of Public Health - administers public health programs including STD programs, smoking cessation, and restaurant inspection. In the majority of the county LACDPH puts letter grades relating to the food cleanliness and safety of a restaurant in the front window of restaurants.
  • Los Angeles County Department of Public Social Services – administers many federal and state welfare programs
  • Los Angeles County Department of Public Works – operates countywide flood control system, constructs and maintains roads in unincorporated areas
  • Los Angeles County District Attorney – prosecutes criminal suspects.
  • Los Angeles County Office of the Public Defender – Defends indigent people accused of criminal offenses.
  • Los Angeles County Probation Department
  • Los Angeles County Sheriff's Department – provides law enforcement services for the unincorporated parts of Los Angeles County, as well as 42 cities.

The Los Angeles County Metropolitan Transportation Authority, despite its name, is not a County department. Technically it is a state-mandated county transportation commission that also operates bus and rail.



Los Angeles County has voted for the Democratic candidate in most of the presidential elections in the past four decades, and has gone Democratic in every election since 1988. However, it did vote twice for Dwight Eisenhower (1952, 1956), Richard Nixon (1968, 1972), and Ronald Reagan (1980, 1984) the latter two of whom were Californians. From 1920 to 1984 it was a bellwether county that always voted for the eventual national winner. Since 1984, it has only voted against the national popular vote winner in 1988 & 2004. In 2008 and 2012, 69% of the electorate voted for Democrat Barack Obama. In 2016, Democrat Hillary Clinton won 71% of the vote, marking the largest percentage of the electorate ever won by a single candidate in the county.

Legal system

The Los Angeles Superior Court, is the county's court of general jurisdiction, while the U.S. District Court for the Central District of California may hear cases where federal jurisdiction is present. Both are headquartered in a large cluster of government buildings in the city's Civic Center.

Historically, the courthouses were county-owned buildings that were maintained at county expense, which created significant friction since the trial court judges, as officials of the state government, had to lobby the county Board of Supervisors for facility renovations and upgrades. In turn, the state judiciary successfully persuaded the state Legislature to authorize the transfer of all courthouses to the state government in 2008 and 2009 (so that judges would have direct control over their own courthouses). Courthouse security is still provided by the county government under a contract with the state.

Unlike the largest city in the United States, New York City, all of the city of Los Angeles and most of its important suburbs are located within a single county. As a result, both the county superior court and the federal district court are respectively the busiest courts of their type in the nation.[46][47]

Many celebrities like O. J. Simpson have been seen in Los Angeles courts. In 2003, the television show Extra (based in nearby Glendale) found itself running so many reports on the legal problems of local celebrities that it spun them off into a separate show, Celebrity Justice.

State cases are appealed to the Court of Appeal for the Second Appellate District, which is also headquartered in the Civic Center, and then to the California Supreme Court, which is headquartered in San Francisco but also hears argument in Los Angeles (again, in the Civic Center). Federal cases are appealed to the Court of Appeals for the Ninth Circuit, which hears them at its branch building in Pasadena. The court of last resort for federal cases is the U.S. Supreme Court in Washington, D.C.
