Los Angeles (LA or L.A.) is the most populous city in the U.S. state of California, and the commercial, financial, and cultural center of Southern California. With an estimated 3.87 million residents within the city limits as of 2025, it is the second-most populous city in the United States, behind New York City, and the largest city in the Western United States. The city has an ethnically and culturally diverse population, and is the principal city of a metropolitan area of 12.9 million people (2024). Greater Los Angeles, a combined statistical area that includes the Los Angeles and Riverside–San Bernardino metropolitan areas, is a sprawling metropolis of over 18 million residents. The majority of the city proper lies in the Los Angeles Basin adjacent to the Pacific Ocean in the west and extending partly through the Santa Monica Mountains and north into the San Fernando Valley, with the city bordering the San Gabriel Valley to its east. It covers about 469 square miles (1,210 km2), and is the county seat and most populated city of Los Angeles County, which is the most populous county in the United States with an estimated 9.86 million residents as of 2022. It is the third-most visited city in the U.S. (after New York City and Miami), with over 3.6 million visitors as of 2023. The area that became Los Angeles was originally inhabited by the indigenous Tongva people and later claimed by Juan Rodríguez Cabrillo for Spain in 1542. The city was founded on September 4, 1781, under Spanish governor Felipe de Neve, on the village of Yaanga. It became a part of the First Mexican Empire in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo and became part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood. The discovery of oil in the 1890s brought rapid growth to the city. The city was further expanded with the completion of the Los Angeles Aqueduct in 1913, which delivers water from Eastern California. Los Angeles has a diverse economy with a broad range of industries. Despite a decline in film production, it is the oldest and one of the largest hubs of film and television production. It has one of the busiest container ports in the Americas. Despite an exodus of commerce, Downtown Los Angeles is evolving as a cultural center with the world's largest showcase of architecture designed by Frank Gehry. In 2024, the Los Angeles metropolitan area had a gross metropolitan product of over $1.295 trillion, making it the city with the third-largest GDP in the world, after New York and Tokyo. Los Angeles hosted the Summer Olympics in 1932 and 1984, and will host the games for a third time in 2028.
Toponymy
On September 4, 1781, a group of 44 settlers known as "Los Pobladores" founded the pueblo (town) they called El Pueblo de Nuestra Señora la Reina de los Ángeles, 'The Town of Our Lady the Queen of the Angels'. The original name of the settlement is disputed; the Guinness Book of World Records rendered it as "El Pueblo de Nuestra Señora la Reina de los Ángeles del Río Porciúncula"; other sources have shortened or alternate versions of the longer name. The local English pronunciation of the name of the city has varied over time. A 1953 article in the journal of the American Name Society asserts that the pronunciation lawss AN-jəl-əs was established following the 1850 incorporation of the city and that since the 1880s the pronunciation lohss ANG-gəl-əs emerged from a trend in California to give places Spanish, or Spanish-sounding, names and pronunciations. In 1908, librarian Charles Fletcher Lummis, who argued for the name's pronunciation with a hard g (), reported that there were at least 12 pronunciation variants. In the early 1900s, the Los Angeles Times advocated for pronouncing it Loce AHNG-hayl-ais (), approximating Spanish [los ˈaŋxeles], by printing the respelling under its masthead for several years. This did not find favor. Since the 1930s, has been most common. In 1934, the United States Board on Geographic Names decreed that this pronunciation be used by the federal government. This was also endorsed in 1952 by a "jury" appointed by Mayor Fletcher Bowron to devise an official pronunciation.
History
Indigenous history The settlement of Indigenous Californians in the modern Los Angeles Basin and the San Fernando Valley was dominated by the Tongva (now also known as the Gabrieleño since the era of Spanish colonization). The historic center of Tongva power in the region was the settlement of Yaanga (Tongva: Iyáangẚ), meaning "place of the poison oak", which would eventually become the site where the Spanish founded the Pueblo de Los Ángeles. Iyáangẚ has also been translated as "the valley of smoke".
Spanish rule In 1542, maritime explorer Juan Rodríguez Cabrillo claimed the present-day area of southern California for the Spanish Empire during an official military expedition northward along the Pacific coast from New Spain. Gaspar de Portolà and Franciscan missionary Juan Crespí reached the present site of Los Angeles on August 2, 1769.
In 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. On September 4, 1781, a group of 44 settlers known as "Los Pobladores" founded the pueblo (town) they called El Pueblo de Nuestra Señora la Reina de los Ángeles, 'The Town of Our Lady the Queen of the Angels'. The present-day city has the largest Roman Catholic archdiocese in the United States. Two-thirds of the Mexican or (New Spain) settlers were mestizo or mulatto, a mixture of African, indigenous, and European ancestry. There was even one Asian Filipino from Manila (Antonio Miranda Rodríguez) who was reassigned to nearby Santa Barbara which was a fortress that needed his gun-smithing skills more. The settlement remained a small ranch town for decades, but by 1820, the population had increased to about 650 residents. Today, the pueblo is commemorated in the historic district of Los Angeles Pueblo Plaza and Olvera Street, the oldest part of Los Angeles.
Mexican rule
New Spain achieved its independence from the Spanish Empire in 1821, after which the pueblo existed within the Mexican Republic. During Mexican rule, Governor Pío Pico made Los Angeles the regional capital of Alta California. By this time, the new republic introduced more secularization acts within the Los Angeles region. In 1846, during the Mexican–American War, marines from the United States occupied the pueblo. This resulted in the siege of Los Angeles, where 150 Mexican militias fought the occupiers, who eventually surrendered. Mexican rule ended following the American Conquest of California, part of the larger Mexican-American War. Americans took control from the Californios after a series of battles, culminating with the signing of the Treaty of Cahuenga on January 13, 1847. The Mexican Cession was formalized in the Treaty of Guadalupe Hidalgo in 1848, which ceded Los Angeles and the rest of Alta California to the United States.
Post-Conquest era
Railroads arrived with the completion of the Southern Pacific line from San Francisco to Los Angeles in 1876 and the Santa Fe Railroad in 1885. Petroleum was discovered in the city and surrounding area in 1892, and by 1923, the discoveries helped California become the country's largest oil producer, accounting for about one-quarter of the world's petroleum output. By 1900, the population had grown to more than 102,000, putting pressure on the city's water supply. The completion of the Los Angeles Aqueduct in 1913, under the supervision of William Mulholland, ensured the continued growth of the city. Because of clauses in the city's charter that prevented the City of Los Angeles from selling or providing water from the aqueduct to any area outside its borders, many adjacent cities and communities felt compelled to join Los Angeles.
Los Angeles created the first municipal zoning ordinance in the United States. On September 14, 1908, the Los Angeles City Council promulgated residential and industrial land use zones. The new ordinance established three residential zones of a single type, where industrial uses were prohibited. The proscriptions included barns, lumber yards, and any industrial land use employing machine-powered equipment. These laws were enforced against industrial properties after the fact. These prohibitions were in addition to existing activities that were already regulated as nuisances. These included explosives warehousing, gas works, oil drilling, slaughterhouses, and tanneries. Although the council designated seven industrial zones, exemptions granted between 1908 and 1915 permitted industrial development within designated residential areas. There are two differences between the 1908 Residence District Ordinance and later zoning laws in the United States. First, the 1908 laws did not establish a comprehensive zoning map as the 1916 New York City Zoning Ordinance did. Second, the residential zones did not distinguish types of housing; they treated apartments, hotels, and detached single-family housing equally. In 1910, Hollywood merged into Los Angeles, with 10 movie companies already operating in the city at the time. By 1921, more than 80 percent of the world's film industry was concentrated in L.A. The money generated by the industry kept the city insulated from much of the economic loss suffered by the rest of the country during the Great Depression. By 1930, the population surpassed one million. In 1932, the city hosted the Summer Olympics.
Post–World War II
During the Second World War, Los Angeles became a major center of wartime manufacturing, such as shipbuilding and aircraft. Calship built hundreds of Liberty Ships and Victory Ships on Terminal Island, and the Los Angeles area was the headquarters of six of the country's major aircraft manufacturers (Douglas Aircraft Company, Hughes Aircraft, Lockheed, North American Aviation, Northrop Corporation, and Vultee). During the war, more aircraft were produced in one year than in all the pre-war years since the Wright brothers flew their first airplane in 1903, combined. Manufacturing in Los Angeles skyrocketed, and as William S. Knudsen, of the National Defense Advisory Commission, put it, "We won because we smothered the enemy in an avalanche of production, the like of which he had never seen, nor dreamed possible." Following World War II, a major influx of new residents and the expansion of defense and aerospace industries accelerated Los Angeles' urbanization. The resulting metropolitan growth caused the city to expand rapidly, sprawling northwest into the San Fernando Valley. The expansion of the state owned Interstate Highway System during the 1950s and 1960s helped propel suburban growth and signaled the demise of the city's privately owned electrified rail system, once the world's largest. As a consequence of World War II, suburban growth, and population density, many amusement parks were built and operated in this area. An example is Beverly Park, which was located at the corner of Beverly Boulevard and La Cienega before being closed and replaced by the Beverly Center. In the late 20th century, Los Angeles substantially reduced the amount of housing that could be built by drastically downzoning the city. In 1960, the city had a total zoned capacity for approximately 10 million people. By 1990, that capacity had fallen to 4.5 million as a result of policy decisions to ban housing through zoning. Racial tensions led to the Watts riots in 1965, resulting in 34 deaths and over 1,000 injuries.
In 1969, California became the birthplace of the Internet, as the first ARPANET transmission was sent from the University of California, Los Angeles (UCLA) to the Stanford Research Institute in Menlo Park. In 1973, Tom Bradley was elected as the city's first African American mayor, serving for five terms until retiring in 1993. Other events in the city during the 1970s included the Symbionese Liberation Army's South Central standoff in 1974 and the Hillside Stranglers murder cases in 1977–1978. In early 1984, the city surpassed Chicago in population to become the second-largest city in the United States. In 1984, the city hosted the Summer Olympic Games for the second time. Despite being boycotted by 14 Communist countries, the 1984 Olympics became more financially successful than any previous, and the second Olympics to turn a profit; the other, according to an analysis of contemporary newspaper reports, was the 1932 Summer Olympics, also held in Los Angeles.
Racial tensions erupted on April 29, 1992, with the acquittal by a Simi Valley jury of four Los Angeles Police Department (LAPD) officers captured on videotape beating Rodney King, culminating in large-scale riots. In 1994, the magnitude 6.7 Northridge earthquake shook the city, causing $12.5 billion in damage and 72 deaths. The century ended with the Rampart scandal, one of the most extensive documented cases of police misconduct in American history.
21st century In 2002, Mayor James Hahn led the campaign against secession, resulting in voters defeating efforts by the San Fernando Valley and Hollywood to secede from the city. In 2022, Karen Bass became the city's first female mayor, making Los Angeles the largest U.S. city to have ever had a woman as mayor. In January 2025, a series of devastating wildfires caused by severe winds swept through Southern California, with the Pacific Palisades fire causing widespread destruction in Los Angeles's northwestern community of Pacific Palisades, with many calling it the most destructive in the history of the city of Los Angeles. In June 2025, the city experienced protests and riots following raids by United States Immigration and Customs Enforcement (ICE). The Trump administration has targeted Los Angeles over its sanctuary city status, sending in hundreds of federal agents to apprehend undocumented immigrants. Trump also dispatched the Army National Guard and US Marines without the consent of local governments. Los Angeles will host the 2028 Summer Olympics and Paralympics, making Los Angeles the third city to host the Olympics three times, after London and Paris.
Geography
Topography
The city of Los Angeles covers a total area of 502.7 square miles (1,302 km2), comprising 468.7 square miles (1,214 km2) of land and 34.0 square miles (88 km2) of water. The city extends for 44 miles (71 km) from north to south and for 29 miles (47 km) from east to west. The perimeter of the city is 342 miles (550 km). Los Angeles is both flat and hilly. The highest point in the city proper is Mount Lukens at 5,074 ft (1,547 m), located in the foothills of the San Gabriel Mountains at the north extent of the Crescenta Valley. The eastern end of the Santa Monica Mountains stretches from Downtown to the Pacific Ocean and separates the Los Angeles Basin from the San Fernando Valley. Other hilly parts of Los Angeles include the Mt. Washington area north of Downtown, eastern parts such as Boyle Heights, the Crenshaw district around the Baldwin Hills, and the San Pedro district. Surrounding the city are much higher mountains. Immediately to the north lie the San Gabriel Mountains, a popular recreation area for Angelenos. Its high point is Mount San Antonio, locally known as Mount Baldy, which reaches 10,064 feet (3,068 m). Further afield, the highest point in southern California is San Gorgonio Mountain, 81 miles (130 km) east of downtown Los Angeles, with a height of 11,503 feet (3,506 m). The Los Angeles River, which is largely seasonal, is the primary drainage channel. It was straightened and lined in 51 miles (82 km) of concrete by the Army Corps of Engineers to act as a flood control channel. The river begins in the Canoga Park district of the city, flows east from the San Fernando Valley along the north edge of the Santa Monica Mountains, and turns south through the city center, flowing to its mouth in the Port of Long Beach at the Pacific Ocean. The smaller Ballona Creek flows into the Santa Monica Bay at Playa del Rey.
Vegetation
Los Angeles is rich in native plant species partly because of its diversity of habitats, including beaches, wetlands, and mountains. The most prevalent plant communities are coastal sage scrub, chaparral shrubland, and riparian woodland. Native plants include the California poppy, matilija poppy, toyon, ceanothus, chamise, coast live oak, sycamore, willow and giant wildrye. Many of these native species, such as the Los Angeles sunflower, have become so rare as to be considered endangered. Mexican fan palms, Canary Island palms, queen palms, date palms, and California fan palms are common in the Los Angeles area, although only the last is native to California, though still not native to the City of Los Angeles. Los Angeles has several official flora:
The official tree of Los Angeles is the coral tree (Erythrina afra). The official flower is the bird of paradise (Strelitzia reginae). The official plant is toyon (Heteromeles arbutifolia).
Fauna
The city has an urban population of bobcats (Lynx rufus). Mange is a common problem in this population. Although Serieys et al. 2014 find selection of immune genetics at several loci they do not demonstrate that this produces a real difference which helps the bobcats to survive future mange outbreaks. Bats, coyotes, raccoons, opossums, skunks, snakes, and squirrels are wild animals commonly found in the Los Angeles area. Mountain lions, mule deer, and other wild animals are also commonly spotted in Southern California.
Geology
Los Angeles is subject to earthquakes because of its location on the Pacific Ring of Fire. The geologic instability has produced numerous faults, which cause approximately 10,000 earthquakes annually in Southern California, though most of them are too small to be felt. The strike-slip San Andreas Fault system, which sits at the boundary between the Pacific Plate and the North American Plate, passes through the Los Angeles metropolitan area. The segment of the fault passing through Southern California experiences a major earthquake roughly every 110 to 140 years, and seismologists have warned about the next "big one", as the last major earthquake was the 1857 Fort Tejon earthquake. The Los Angeles basin and metropolitan area are also at risk from blind thrust earthquakes. Major earthquakes that have hit the Los Angeles area include the 1933 Long Beach, 1971 San Fernando, 1987 Whittier Narrows, and the 1994 Northridge events. All but a few are of low intensity and are not felt. The USGS has released the UCERF California earthquake forecast, which models earthquake occurrence in California. Parts of the city are also vulnerable to tsunamis; harbor areas were damaged by waves from Aleutian Islands earthquake in 1946, Valdivia earthquake in 1960, Alaska earthquake in 1964, Chile earthquake in 2010 and Japan earthquake in 2011.
Cityscape
The city is divided into many different districts and neighborhoods, some of which had been separately incorporated cities that eventually merged with Los Angeles. These neighborhoods were developed piecemeal, and are well-defined enough that the city has signage which marks nearly all of them.
Overview
The city's street patterns generally follow a grid plan, with uniform block lengths and occasional roads that cut across blocks. However, this is complicated by rugged terrain, which has necessitated having different grids for each of the valleys that Los Angeles covers. Major streets are designed to move large volumes of traffic through many parts of the city, many of which are extremely long; Sepulveda Boulevard is 43 miles (69 km) long, while Foothill Boulevard is over 60 miles (97 km) long, reaching as far east as San Bernardino. Drivers in Los Angeles suffer from one of the worst rush hour periods in the world, according to an annual traffic index by navigation system maker, TomTom. LA drivers spend an additional 92 hours in traffic each year. During the peak rush hour, there is 80% congestion, according to the index. Los Angeles is often characterized by the presence of low-rise buildings, in contrast to New York City. Outside of a few centers such as downtown, Warner Center, Century City, Koreatown, Miracle Mile, Hollywood, and Westwood, skyscrapers and high-rise buildings are not common in Los Angeles. However, downtown Los Angeles alone has many buildings over 30 stories, with fourteen over 50 stories, and two over 70 stories, the tallest of which is the Wilshire Grand Center.
Climate
Los Angeles has a two-season semi-arid climate (Köppen: BSh) with dry summers and mild to warm winters, but it receives more annual precipitation than most semi-arid climates, narrowly missing the boundary of a Mediterranean climate (Köppen: Csb on the coast, Csa otherwise). Daytime temperatures are generally temperate all year round. In winter, they average around 68 °F (20 °C). Autumn months tend to be hot, with major heat waves a common occurrence in September and October, while the spring months tend to be cooler and experience more precipitation. Los Angeles has plenty of sunshine throughout the year, with an average of only 35 days with measurable precipitation annually. Temperatures in the coastal basin exceed 90 °F (32 °C) on a dozen or so days in the year, from one day a month in April, May, June and November to three days a month in July, August, October and to five days in September. Temperatures in the San Fernando and San Gabriel Valleys are considerably warmer. Temperatures are subject to substantial daily swings; in inland areas, the difference between the average daily low and the average daily high is over 30 °F (17 °C). The average annual temperature of the sea is 63 °F (17 °C), from 58 °F (14 °C) in January to 68 °F (20 °C) in August. Hours of sunshine total more than 3,000 per year, from an average of 7 hours of sunshine per day in December to an average of 12 in July. Due to the mountainous terrain of the surrounding region, the Los Angeles area contains a large number of distinct microclimates, causing extreme variations in temperature in close physical proximity to each other. For example, the average July maximum temperature at the Santa Monica Pier is 70 °F (21 °C) whereas it is 95 °F (35 °C) in Canoga Park, 15 miles (24 km) away. The city, like much of the Southern Californian coast, is subject to a late spring/early summer weather phenomenon called "June Gloom". This involves overcast or foggy skies in the morning that yield to sun by early afternoon.
More recently, statewide droughts in California have further strained the city's water security. Downtown Los Angeles averages 14.67 in (373 mm) of precipitation annually, mainly occurring between November and March, generally in the form of moderate rain showers, but sometimes as heavy rainfall during winter storms. Rainfall is usually higher in the hills and coastal slopes of the mountains because of orographic uplift. Summer days are usually rainless. Rarely, an incursion of moist air from the south or east can bring brief thunderstorms in late summer, especially to the mountains. The coast gets slightly less rainfall, while the inland and mountain areas get considerably more. Years of average rainfall are rare. The usual pattern is a year-to-year variability, with a short string of dry years of 5–10 in (130–250 mm) rainfall, followed by one or two wet years with more than 20 in (510 mm). Wet years are usually associated with warm water El Niño conditions in the Pacific, dry years with cooler water La Niña episodes. A series of rainy days can bring floods to the lowlands and mudslides to the hills, especially after wildfires have denuded the slopes.
Both freezing temperatures and snowfall are extremely rare in the city basin and along the coast, with the last occurrence of a 32 °F (0 °C) reading at the downtown station being January 29, 1979; freezing temperatures occur nearly every year in valley locations, while the mountains within city limits typically receive snowfall every winter. The greatest snowfall recorded in downtown Los Angeles was 2.0 inches (5 cm) on January 15, 1932. While the most recent snowfall occurred in February 2019, the first snowfall since 1962, with snow falling in areas adjacent to Los Angeles as recently as January 2021. Brief, localized instances of hail can occur on rare occasions, but are more common than snowfall. At the official downtown station, the highest recorded temperature is 113 °F (45 °C) on September 27, 2010, while the lowest is 28 °F (−2 °C), on January 4, 1949. Within the City of Los Angeles, the highest temperature ever officially recorded is 121 °F (49 °C), on September 6, 2020, at the weather station at Pierce College in the San Fernando Valley neighborhood of Woodland Hills. During autumn and winter, Santa Ana winds sometimes bring much warmer and drier conditions to Los Angeles, and raise wildfire risk.
Environmental issues
Owing to geography, heavy reliance on automobiles, and the Los Angeles/Long Beach port complex, Los Angeles suffers from air pollution in the form of smog. The Los Angeles Basin and the San Fernando Valley are susceptible to atmospheric inversion, which holds in the exhaust from road vehicles, airplanes, locomotives, shipping, manufacturing, and other sources.
The smog season lasts from approximately May to October. While other large cities rely on rain to clear smog, Los Angeles gets only 15 inches (380 mm) of rain each year: pollution accumulates over many consecutive days. Issues of air quality in Los Angeles and other major cities led to the passage of early national environmental legislation, including the Clean Air Act. When the act was passed, California was unable to create a State Implementation Plan that would enable it to meet the new air quality standards, largely because of the level of pollution in Los Angeles generated by older vehicles. More recently, the state of California has led the nation in working to limit pollution by mandating low-emission vehicles. Smog is expected to continue to drop in the coming years because of aggressive steps to reduce it, which include electric and hybrid cars, improvements in mass transit, and other measures. The number of Stage 1 smog alerts in Los Angeles has declined from over 100 per year in the 1970s to almost zero in the new millennium. Despite improvement, the 2006 and 2007 annual reports of the American Lung Association ranked the city as the most polluted in the country with short-term particle pollution and year-round particle pollution. In 2008, the city was ranked the second most polluted and again had the highest year-round particulate pollution. The city met its goal of providing 20 percent of the city's power from renewable sources in 2010. The American Lung Association's 2013 survey ranks the metro area as having the nation's worst smog, and fourth in both short-term and year-round pollution amounts. Los Angeles is also home to the nation's largest urban oil field. There are more than 700 active oil wells within 1,500 feet (460 m) of homes, churches, schools, and hospitals in the city, a situation about which the EPA has voiced serious concerns.
Demographics
Total population, age, and sex The 2020 U.S. census reported Los Angeles had a population of 3,898,747. The population density was 8,304.2 people per square mile (3,168 people per square kilometer). 5.2% of the total population is under 5 years old, 19.5% under 18 and 13.8% 65 years old and over. Females make up 50.2% of the total population. The city has lost 0.5% of its population since the 2020 census. The latest official estimate (2025) from the U.S. Census Bureau showed the population of Los Angeles County shrinking fastest among large U.S. counties nationwide.
Housing and families Owner-occupied housing units make up 36.3% of the total Los Angeles housing units, and they cost $879,500 on average. (2019–2023) With a mortgage, the median selected monthly owner costs are $3,399, and without a mortgage $950. (2019–2023) Median gross rent is $1,879. (2019–2023) There are 1,419,663 households in Los Angeles, with an average of 2.64 people being part of them. (2019–2023).
Languages Well over 200 languages are spoken in Los Angeles. The 2021 American Community Survey of the U.S. Census Bureau reported that some 56.8% of city residents aged five and older spoke a language other than English at home.
Economy Around 66.5% of the total population aged 16 and over make up Los Angeles in civilian labor force, while among female residents aged 16 and over the percentage is 61.0%. In 2022, accommodation and food services made $17,366,966, health care and social assistance sectors made $46,297,839, transportation and warehousing $25,410,257, and the retail sector $81,351,523, with residents spending an average of $21,281 in retail purchases throughout the year. From 2019 to 2023, the median household income in Los Angeles was $80,366 (2023 dollars), while the per capita income in the past 12 months was $46,270. About 16.5% of Los Angeles residents have total incomes below the federal poverty line.
Race and ethnicity
According to data in 2023 from the United States Census Bureau, Los Angeles's population is 47.2% Hispanic or Latino, 28.3% non-Hispanic White, 8.5% Black, 12.0% Asian, 1.2% Native American and 0.1% Pacific Islander. Ethnic enclaves like Chinatown, Historic Filipinotown, Koreatown, Little Armenia, Little Ethiopia, Tehrangeles, Little Tokyo, Little Bangladesh, and Thai Town provide examples of the multicultural character of Los Angeles. People of Mexican ancestry formed the largest national origin group, comprising 31.9% of the city's population, followed by those of Salvadoran (6.0%) and Guatemalan (3.6%) heritage. Descendants of Mexicans and Central Americans have long-established communities in Los Angeles and are spread throughout the entire metropolitan area. They are most heavily concentrated in regions around Downtown, such as East Los Angeles, Northeast Los Angeles and Westlake. The largest Asian ethnic groups are Filipinos (3.2%) and Koreans (2.9%), which have their own established ethnic enclaves—Koreatown in the Wilshire Center and Historic Filipinotown. Chinese people, which make up 1.8% of Los Angeles's population, reside mostly outside of Los Angeles city limits, in the San Gabriel Valley of eastern Los Angeles County, but make a sizable presence in the city, notably in Chinatown. Chinatown and Thaitown are also home to many Thais and Cambodians, which make up 0.3% and 0.1% of Los Angeles's population, respectively. The Japanese comprise 0.9% of the city's population and have an established Little Tokyo in the city's downtown, and another significant community of Japanese Americans is in the Sawtelle district of West Los Angeles. Indians make up 0.9% of the city's population. Vietnamese make up 0.5% of Los Angeles's population. Los Angeles is also home to Caucasian and Middle Eastern communities, such as Armenians, Assyrians, and Iranians, many of whom live in enclaves like Little Armenia and Tehrangeles. Due to racial segregation that ended in the late 20th century, African Americans have been the predominant ethnic group in South Los Angeles, which has emerged as the largest African-American community in the western United States since the 1960s. The neighborhoods of South Los Angeles with highest concentration of African Americans include Crenshaw, Baldwin Hills, Leimert Park, Hyde Park, Gramercy Park, Manchester Square and Watts. Since the 1990s, the growing cost of living in the city has significantly impacted the African American population. African Americans are the fastest declining population in the city, and many of the formerly predominantly African American neighborhoods have become much more diverse. There is also a sizable Eritrean and Ethiopian community in the Fairfax region. Los Angeles has the second-largest Mexican, Armenian, Salvadoran, Filipino, and Guatemalan populations by city in the world, the third-largest Canadian population in the world, and has the largest Japanese, Iranian/Persian, Cambodian, and Romani (Gypsy) populations in the country. The Italian community is concentrated in San Pedro. Most of Los Angeles's foreign-born population were born in Mexico, El Salvador, Guatemala, the Philippines and South Korea.
Religion
According to a 2014 study by the Pew Research Center, Christianity is the most prevalently practiced religion in Los Angeles (65%). The Roman Catholic Archdiocese of Los Angeles is the largest archdiocese in the country. Cardinal Roger Mahony, as the archbishop, oversaw construction of the Cathedral of Our Lady of the Angels, which opened in September 2002 in downtown Los Angeles. In 2011, the once common, but ultimately lapsed, custom of conducting a procession and Mass in honor of Nuestra Señora de los Ángeles, in commemoration of the founding of the City of Los Angeles in 1781, was revived by the Queen of Angels Foundation and its founder Mark Albert, with the support of the Archdiocese of Los Angeles as well as several civic leaders. The recently revived custom is a continuation of the original processions and Masses that commenced on the first anniversary of the founding of Los Angeles in 1782 and continued for nearly a century thereafter.
With 621,000 Jews in the metropolitan area, the region has the second-largest population of Jews in the United States, after New York City. Many of Los Angeles's Jews now live on the Westside and in the San Fernando Valley, though Boyle Heights once had a large Jewish population before World War II due to restrictive housing covenants. Major Orthodox Jewish neighborhoods include Hancock Park, Pico-Robertson, and Valley Village, while Jewish Israelis are well represented in the Encino and Tarzana neighborhoods, and Persian Jews in Beverly Hills. Many varieties of Judaism are represented in the greater Los Angeles area, including Reform, Conservative, Orthodox, and Reconstructionist. The Breed Street Shul in East Los Angeles, built in 1923, was the largest synagogue west of Chicago in its early decades; it is no longer in daily use as a synagogue and is being converted to a museum and community center. The Kabbalah Centre also has a presence in the city. The International Church of the Foursquare Gospel was founded in Los Angeles by Aimee Semple McPherson in 1923 and remains headquartered there to this day. For many years, the church convened at Angelus Temple, which, at its construction, was one of the largest churches in the country.
Los Angeles has had a rich and influential Protestant tradition. The first Protestant service in Los Angeles was a Methodist meeting held in a private home in 1850, and the oldest Protestant church still operating, First Congregational Church, was founded in 1867. In the early 1900s the Bible Institute Of Los Angeles published the founding documents of the Christian Fundamentalist movement and the Azusa Street Revival launched Pentecostalism. The Metropolitan Community Church also had its origins in the Los Angeles area. Important churches in the city include First Presbyterian Church of Hollywood, Bel Air Presbyterian Church, First African Methodist Episcopal Church of Los Angeles, West Angeles Church of God in Christ, Second Baptist Church, Crenshaw Christian Center, McCarty Memorial Christian Church, and First Congregational Church.
The Hollywood region of Los Angeles also has several significant headquarters and churches, including the Celebrity Center of the Church of Scientology. Because of Los Angeles's large multi-ethnic population, a wide variety of faiths are practiced, including Buddhism, Hinduism, Islam, Zoroastrianism, Sikhism, Baháʼí, various Eastern Orthodox Churches, Sufism, Shintoism, Taoism, Confucianism, Chinese folk religion and countless others. Immigrants from Asia, for example, have formed several significant Buddhist congregations, making the city home to the greatest variety of Buddhists in the world. The first Buddhist joss house was founded in the city in 1875. Atheism and other secular beliefs are also common, as the city is the largest in the Western U.S. Unchurched Belt.
Homelessness
As of January 2024, there are 45,252 homeless people in the City of Los Angeles, comprising roughly 60% of the homeless population of LA County. This is a 2.2% decrease from the previous year (with a 0.3% decrease in the overall homeless population of LA County). The epicenter of homelessness in Los Angeles is the Skid Row neighborhood, which contains 8,000 homeless people, one of the largest stable populations of homeless people in the United States. The increased homeless population in Los Angeles has been attributed to lack of housing affordability and to substance abuse. Almost 60 percent of the 82,955 people who became newly homeless in 2019 said their homelessness was because of economic hardship. In Los Angeles, black people are roughly four times more likely to experience homelessness.
Economy
The economy of Los Angeles is driven by international trade, entertainment (television, motion pictures, video games, music recording, and production), aerospace, technology, petroleum, fashion, apparel, and tourism. Other significant industries include finance, telecommunications, law, healthcare, and transportation. In the 2017 Global Financial Centres Index, Los Angeles was ranked the 19th most competitive financial center in the world and sixth most competitive in the U.S. after New York City, San Francisco, Chicago, Boston, and Washington, D.C. Although many businesses have left downtown Los Angeles following the COVID-19 pandemic, efforts are underway to re-invent the neighborhood as a cultural center with a large architectural showcase in Bunker Hill designed by Frank Gehry. Of the five major film studios, only Paramount Pictures is within Los Angeles's city limits; it is located in the so-called Thirty-Mile Zone of entertainment headquarters in Southern California. Their parent company Paramount Skydance Corporation has had its corporate headquarters in Los Angeles since 2025. Los Angeles is still the largest manufacturing center in the United States by employment, but now second after the New York metropolitan area by dollar value of goods manufactured. Disadvantages of manufacturing production in Los Angeles are its relative geographical isolation from most major North American markets, lack of a reliable water supply, and lack of an adequate skilled labor force, in addition to a significantly complex regulatory environment. The contiguous ports of Los Angeles and Long Beach together comprise the busiest port in the United States by some measures and the fifth busiest port in the world, vital to trade within the Pacific Rim.
The Los Angeles metropolitan area has a gross metropolitan product of over $1.0 trillion (as of 2018), making it the third-largest economic metropolitan area in the world, after New York and Tokyo. Los Angeles has been classified an "alpha world city" according to a 2012 study by a group at Loughborough University. As of 2018, Los Angeles is home to three Fortune 500 companies: AECOM, CBRE Group, and Reliance Steel & Aluminum Co. Other companies headquartered in Los Angeles and the surrounding metropolitan area include The Aerospace Corporation, California Pizza Kitchen, Capital Group Companies, Deluxe Entertainment Services Group, Dine Brands Global, DreamWorks Animation, Dollar Shave Club, Fandango Media, Farmers Insurance Group, Forever 21, Hulu, Panda Express, SpaceX, Ubisoft Film & Television, The Walt Disney Company, Universal Pictures, Warner Bros., Warner Music Group, a
