Los Angeles County, officially the County of Los Angeles,^[7] is the most populous county in the Los Angeles metropolitan area of the U.S. state of California and is the most populous county in the United States,^[8] with more than 10 million inhabitants as of 2017^[update].^[9] As such, it is the largest non-state level government entity in the United States. Its population is larger than that of 41 individual U.S. states. It is the third-largest metropolitan economy in the world, with a Nominal GDP of over $700 billion—larger than the GDPs of Belgium, Saudi Arabia, Norway, and Taiwan.^[10] It has 88 incorporated cities and many unincorporated areas and, at 4,083 square miles (10,570 km²), it is larger than the combined areas of Delaware and Rhode Island. The county is home to more than one-quarter of California residents and is one of the most ethnically diverse counties in the U.S.^[11] Its county seat, Los Angeles, is also California's most populous city with about 4 million people.

History

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:

• 
  Azusa (encompassed the foothill communities east of the San Gabriel River, including present-day Covina and Duarte)


• 
  El Monte (encompassed communities in the Whittier Narrows area, including present-day El Monte, La Puente and Monterey Park)
  
  • Azusa and El Monte Townships were merged for the 1870 census.


• 
  City of Los Angeles (then consisting solely of its four-league Spanish land grant)


• 
  Los Angeles Township (consisted of areas surrounding the City of Los Angeles, including the San Fernando Valley and present-day West Los Angeles and East Los Angeles. Most of this area has now been annexed to the city of Los Angeles)


• 
  Los Nietos (consisted of areas south of the Whittier Narrows and Puente Hills south to present-day Long Beach, centered on the early settlement at Los Nietos. Some of this area is now in Orange County)


• 
  San Jose (consisted of the eastern portions of the county drained by San Jose Creek, including what is now the cities of Pomona, Claremont and Walnut)


• 
  San Gabriel (consisted of the western San Gabriel Valley and foothill communities, including present-day Alhambra and Pasadena. Centered on the Mission San Gabriel)


• 
  Santa Ana (consisted of what is now northern and central Orange County, including what is now Fullerton, Huntington Beach and City of Orange. Centered on Santa Ana).
  
  • For the 1870 census, Annaheim district was enumerated separately.


• 
  San Juan (consisted of what is now southern Orange County. Centered on Mission San Juan Capistrano).


• 
  San Pedro (consisted of the present-day South Bay communities, Compton and western Long Beach. Centered on the wharf of San Pedro. Renamed Wilmington Township by 1870).


• 
  Tejon (consisted of all of northern Los Angeles County and what is now southern Kern County. Centered on Fort Tejon)
  
  • When Kern County was formed, the portion of the township remaining in Los Angeles County became Soledad Township^[14]

Law, government and politics

Government

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:

The Grand Avenue entrance of the Stanley Mosk Courthouse.

• 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.

Politics

Overview

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.^{[citation needed]}

Voter registration

In the United States House of Representatives, Los Angeles County is split between 18 congressional districts:^[42]
In the California State Senate, Los Angeles County is split between 15 legislative districts:^[43]
In the California State Assembly, Los Angeles County is split between 24 legislative districts:^[44]

On November 4, 2008, Los Angeles County was almost evenly split over Proposition 8 which amended the California Constitution to ban same-sex marriages. The county voted for the amendment 50.04% with a margin of 2,385 votes.^[45]

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.

The county's most visited park is Griffith Park, owned by the city of Los Angeles. The county is also known for the annual Rose Parade in Pasadena, the annual Los Angeles County Fair in Pomona, the Los Angeles County Museum of Art, the Los Angeles Zoo, the Natural History Museum of Los Angeles County, the La Brea Tar Pits, the Arboretum of Los Angeles, and two horse racetracks and two car racetracks (Pomona Raceway and Irwindale Speedway), also the RMS Queen Mary located in Long Beach, and the Long Beach Grand Prix, and miles of beaches—from Zuma to Cabrillo.

Venice Beach is a popular attraction where its Muscle Beach used to find throngs of tourists admiring "hardbodies". Today, it is more arts-centered. Santa Monica's pier is a well known tourist spot, famous for its ferris wheel and bumper car rides, which were featured in the introductory segment of the television sitcom Three's Company. Further north in Pacific Palisades one finds the beaches used in the television series Baywatch.^{[citation needed]} The fabled Malibu, home of many a film or television star, lies west of it.

In the mountain, canyon, and desert areas one may find Vasquez Rocks Natural Area Park, where many old Westerns were filmed. Mount Wilson Observatory in the San Gabriel Mountains is open for the public to view astronomical stars from its telescope, now computer-assisted. Many county residents find relaxation in water skiing and swimming at Castaic Lake Recreation Area – the county's largest park by area – as well as enjoying natural surroundings and starry nights at Saddleback Butte State Park in the eastern Antelope Valley – California State Parks' largest in area within the county. The California Poppy Reserve is located in the western Antelope Valley and shows off the State's flower in great quantity on its rolling hills every spring.

Rail

Los Angeles is a major freight-railroad transportation center, largely due to the large volumes of freight moving in and out of the county's sea port facilities. The ports are connected to the downtown rail yards and to the main lines of Union Pacific and Burlington Northern Santa Fe headed east via a grade-separated, freight rail corridor known as the Alameda Corridor.

Passenger rail service is provided in the county by Amtrak, Los Angeles Metro Rail and Metrolink.

Amtrak has the following intercity Amtrak service at Union Station in the city of Los Angeles:

• The Pacific Surfliner to Santa Barbara, San Luis Obispo, and San Diego.


• The Coast Starlight to Seattle.


• The Southwest Chief to Chicago.


• The Sunset Limited to New Orleans and Orlando.

Union Station is also the primary hub for Metrolink commuter rail, which serves much of the Greater Los Angeles Area.

Light rail, subway (heavy rail), and long-distance bus service are all provided by the Los Angeles County Metropolitan Transportation Authority (Metro).

Sea

The county's two main seaports are the Port of Los Angeles and the Port of Long Beach. Together they handle over a quarter of all container traffic entering the United States, making the complex the largest and most important port in the country, and the third-largest port in the world by shipping volume.

The Port of Los Angeles is the largest cruise ship center on the West Coast, handling more than 1 million passengers annually.

The Port of Long Beach is home to the Sea Launch program, which uses a floating launch platform to insert payloads into orbits that would be difficult to attain from existing land-based launch sites.

Ferries link the Catalina Island city of Avalon to the mainland.
