Los Angeles metropolitan area is a large urbanized region centered on the city of Los Angeles in Southern California. The region includes numerous adjacent cities and counties such as Long Beach, Anaheim, Glendale, and Pasadena, forming a contiguous complex that shapes much of Southern California's social, cultural, and economic life. It is a global hub linked to international centers like Tokyo, London, Mexico City, and New York City through commerce, media, and transportation networks.
Geography and extent
The metropolitan region spans coastal plains, inland valleys, and mountain ranges including the Santa Monica Mountains, San Gabriel Mountains, and the Santa Ana Mountains, and borders the Pacific Ocean near Santa Monica Bay and San Pedro Bay. Core urban counties include Los Angeles County, with spillover into parts of Orange County, Riverside County, and San Bernardino County that connect via corridors such as the San Gabriel Valley and the Pomona Valley.

Major adjacent municipalities and districts include Beverly Hills, Inglewood, Torrance, Simi Valley, Ventura, Huntington Beach, Irvine, Fullerton, and Chino Hills.
History and development
The region's development was influenced by indigenous peoples such as the Tongva and Chumash prior to colonization by Spanish Empire expeditions and establishment of the Presidio of Los Angeles and Pueblo de Los Ángeles. Mexican period events like the Secularization of the Missions reshaped land tenure before the Mexican–American War and the Treaty of Guadalupe Hidalgo integrated the area into the United States. 19th-century growth accelerated with the Southern Pacific and Santa Fe Railway expansions, the Southern California land boom, and discoveries linked to the Los Angeles Aqueduct and water politics exemplified by figures like William Mulholland. 20th-century transformations arose from the rise of Hollywood, the development of Los Angeles International Airport, wartime production tied to Boeing and Lockheed Corporation, and postwar suburbanization in places such as Orange County and San Bernardino County.
Demographics and population
The metropolitan population comprises diverse communities including large populations of Mexican Americans, Salvadoran Americans, Filipino Americans, Korean Americans, and Armenian Americans concentrated in neighborhoods like Echo Park, MacArthur Park, Pico-Union, Koreatown, and Glendale. Immigration waves from Latin America, East Asia, and Southeast Asia influenced settlement patterns alongside domestic migration from regions like the Midwest and Pacific Northwest. Significant demographic centers include Downtown Los Angeles, Santa Ana, Riverside, and San Bernardino, with socioeconomic contrasts between high-income enclaves such as Beverly Hills and Newport Beach and lower-income communities in the Skid Row and parts of South Los Angeles.
Economy and major industries
The metropolitan economy encompasses entertainment giants like Walt Disney Company, Warner Bros., Paramount Pictures, and Netflix; technology firms including Snap Inc., Google offices, and startups in Silicon Beach; aerospace and defense contractors such as Northrop Grumman, Raytheon Technologies, and SpaceX facilities; major port operations at the Port of Los Angeles and Port of Long Beach forming the San Pedro Bay Port Complex; finance and real estate led by institutions like Wells Fargo regional centers and commercial hubs in Century City and Financial District, Los Angeles.
