Seal prior to 2004 lawsuit threat
Los Angeles County is a county in Californiamarker and is by far the most populous county in the United Statesmarker. Figures from the U.S. Census Bureau give an estimated 2008 population of 9,862,049 residents, while the California State government's population bureau lists a January 1, 2009, estimate of 10,393,185. The county seat is the city of Los Angelesmarker, the largest city in Californiamarker.

The county is home to 88 incorporated cities and many unincorporated areas. The southern portion is the most heavily urbanized area and is home to the vast majority of the population which lives along the Southern California coastline and the inland basins and valleys. The northern half is a large expanse of less-populated desert including the Santa Clarita Valleymarker and the Antelope Valleymarker, which encompasses the northeastern part of the county and is adjacent to Kern Countymarker. In between these portions of the county sit the San Gabriel Mountainsmarker and the vast wilderness known as the Angeles National Forestmarker.

One of the most diverse counties in the country, it holds most of the principal cities encompassing the Greater Los Angeles Area and is the core of the five counties that make up the area. In 2004, the county's population was larger than the individual populations of 42 states considered separately, and on that basis, is more populous than the aggregate of the 11 least populous states. Similar in land area to the state of Connecticutmarker and in population to the state of Michiganmarker, the county is home to over a quarter of all California residents. According to the United States Conference of Mayors, if Los Angeles County were a nation, it would boast a GDP among the twenty largest countries in the world.


Los Angeles County was one of the original counties of Californiamarker, created at the time of statehood in 1850. The large area once included parts of what is now known as Kern County, San Bernardino County, Riverside County and Orange County. These parts of the county's territory were given to San Bernardino Countymarker in 1853, to Kern Countymarker in 1866 and to Orange Countymarker in 1889. In 1893, part of San Bernardino county became Riverside County.

The county was targeted with the threat of legal action by the ACLU in 2004 regarding a small cross on its seal. The ACLU said that separation of church and state prohibited this display.


With 4,061 square miles (10,517 km²), Los Angeles County borders of coast on the Pacific Oceanmarker and encompasses numerous other natural landscapes including towering mountain ranges, deep valleys, forests, islands, lakes, rivers, and desert. The county contains the following rivers: Los Angeles River, Rio Hondo, the San Gabriel River and the Santa Clara River. The primary mountain ranges are the Santa Monica Mountainsmarker and the San Gabriel Mountainsmarker. It also includes the westernmost part of the Mojave Desert, and San Clemente Islandmarker and Santa Catalina Islandmarker in the Pacific Ocean.

Most of the population of Los Angeles County is located in the south and southwest. The major population centers are the Los Angeles Basin and the San Fernandomarker and San Gabriel Valleys. Moderate populations are in the Santa Claritamarker, Crescenta and The Antelope Valleymarker. The area north of the Santa Clarita Valley (Northwest Los Angeles County, adjacent to Venturamarker and Kernmarker counties) is mostly mountainous, rugged, well-timbered and filled with coniferous forests that receives plentiful snow in the winter, right to the point of blizzard conditions. This area is less populated. Mountains in this area include San Emigdio Mountainsmarker, the southernmost part of Tehachapi Mountains, and the Sierra Pelona Mountains.

Most of the highest peaks in the county are located in the San Gabriel Mountainsmarker, which are part of the Transverse Ranges. They include Mount San Antoniomarker (10,064 ft) at the Los Angeles-San Bernardinomarker county lines, Mount Baden-Powellmarker (9,399 ft), Mount Burnhammarker (8,997 ft), and the well-known Mount Wilsonmarker (5,710 ft) where the Mount Wilson Observatorymarker is located. Several smaller, lower peaks are located in the northern, western, and southwestern Los Angeles County.

The county has a total area of 4,752 square miles (12,308 km²), of which, 4,061 square miles (10,518 km²) of it is land and 691 square miles (1,791 km²) of it (14.55%) is water.

For more information about the primary exception, see the Transportation in Los Angeles article.

Both the freeways and streets are notorious for severe traffic congestion, and the area's freeway-to-freeway interchanges regularly rank among the top 10 most congested points in the country.

Law, government and politics

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. The county government is managed on a day-to-day basis by a Chief Executive Officer, currently William T Fujioka, and is organized into many departments, each of which is enormous in comparison to equivalent county-level (and even state-level) departments anywhere else in the United States. Some of the larger or better-known departments include:

The Grand Avenue entrance of the Stanley Mosk Courthouse.

  • Los Angeles County Coronermarker – performs autopsies and determines the cause of death for those who die without medical supervision.
  • Los Angeles County Community Development Commission – serves as the County's housing authority as well as the housing and community and economic development agency with wide-ranging programs that benefit residents and business owners in unincorporated County areas and in various incorporated cities.
  • Los Angeles County Department of Beaches and Harbors
  • Los Angeles County Department of Children and Family Services – administers foster care
  • Los Angeles County Fire Department – provides fire protection, suppression, and prevention as well as emergency medical services
  • Los Angeles County Department of Health Services – operates several county hospitals and a network of primary care clinics, and also runs the public health system, which has a requirement that all restaurants in the unincorporated County and the majority of independent cities prominently post their food safety inspection grade in their front window
  • Los Angeles County Department of Parks and Recreation – administers public parks and the largest public golf course system in the U.S.
  • Los Angeles County Department of Public Social Services – administers many federal and state welfare programs
  • Los Angeles County Department of Public Worksmarker – operates countywide flood control system, constructs and maintains roads in unincorporated areas

  • Los Angeles County Probation Department
  • Los Angeles County Public Defender – defends indigent criminal suspects
  • Los Angeles County Public Library – operates a large network of branch libraries
  • Los Angeles County Sheriff's Department – provides law enforcement services to unincorporated areas and cities that do not have their own police departments, and operates the county jails. The LASD is the largest county Sheriff's Department in the United States.
    • Los Angeles County Disaster Communications Service ( DCS )is a volunteer organization administered by the Sheriff's Department Emergency Operations Bureau for the Los Angeles County Board of Supervisors. Their main function, authorized under County Ordinance, is to provide volunteer disaster relief communication for the citizens of Los Angeles County.
  • Los Angeles County Department of Consumer Affairs – offers consumers in the county a variety of services including: consumer and real estate counseling, mediation, and small claims counseling. The department also investigates: consumer complains, real estate fraud and identity theft issues.

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.

The Los Angeles Superior Court, which covers the entire county, is not a County department but a division of the State's trial court system. The courthouses, however, are county-owned buildings that are maintained at county expense.

Legal system

The Los Angeles County Superior Court has jurisdiction over all cases arising under state law, while the U.S. District Court for the Central District of California hears all federal cases. Both are headquartered in a large cluster of government buildings in the city's Civic Center.

Unlike the largest city in the United Statesmarker, New York Citymarker, 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.

Many celebrities like O.J. Simpson have been seen in Los Angeles courts. In 2003, the tabloid 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 Courtmarker, which is headquartered in San Franciscomarker 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.marker Supreme Courtmarker in Washington, D.C.marker
