It has the third-largest metropolitan economy in the world, with a Nominal GDP of more than $700 billion. 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 United States. Its county seat, Los Angeles, is also California's most populous city and the second most populous city in the United States, with about four million residents.
Los Angeles County is one of the original counties of California, created at the time of statehood in 1850. 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 state line of Nevada. 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:

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).

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 2020, the Board of Supervisors oversees a $35.5 billion annual budget and over 112,000 employees. 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 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 tends to favor the Democratic Party. Even when California was a state that favored the Republican Party, the county would go for the Democratic nominee. It has voted for the Democratic candidate in every presidential election cycle 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 California politicians. 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 and 2004. In 2008 and 2012, sixty percent of the electorate voted for Democrat Barack Obama. In 2016, Democrat Hillary Clinton won 71% of the vote, marking both the largest margin of any Democratic victory in the county as well as the largest percentage of the electorate ever won by a single candidate in the county.

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

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.
Many celebrities 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.
