Population 24.2 million

Southern California (SoCal) is a megaregion, or megapolitan area, in the southern area of the U.S. state of California. Large urban areas include Greater Los Angeles, Greater San Diego, and the Inland Empire. The urban area stretches along the coast from Ventura through the Southland and Inland Empire to San Diego, spilling over the border into Tijuana. Southern California, along with the San Francisco Bay Area, is a major cultural and economic center for the State of California and beyond.

To the west of Southern California lies the Pacific Ocean and Channel Islands; to the south is the international border between the United States and Mexico; to the east are the Colorado Desert and the Colorado River at the state's border with Arizona, and the Mojave Desert with the state's border with Nevada beyond.

Introduction

Its population encompasses a total of five metropolitan areas: Los Angeles, Riverside-San Bernardino, San Diego, Oxnard-Thousand Oaks and the El Centro area. Out of these, three are major metropolitan areas, each of which have over 3 million people; the Los Angeles area with over 12 million inhabitants, the Riverside-San Bernardino area with over 4 million inhabitants, and the San Diego area with over 3 million inhabitants. The region as a whole is practically identical in population to Texas, with more than 24.2 million people, and is the nation's most populous region behind the urban seaboard of the Northeastern United States.

Though there is no official definition for the northern boundary of Southern California, most definitions in use include all the land south of the he Sierra Nevada Mountains and the Tehachapi Mountains, the latter located about 70 miles (113 km) north of Los Angeles.[1] Southern California is a culturally diverse and well known area worldwide. Many tourists frequent South Coast for it's popular beaches, and the eastern Desert for it's dramatic open spaces.

Within its boundaries are two major world cities, Los Angeles and San Diego, as well as three of the country's largest metropolitan areas.[2] With a population of 1,336,865, San Diego is the second most populous city in California, and the eighth most populous in the U.S. Just to the north, with a population of 4,094,764, Los Angeles is the most populous city in California, and the second most populous in the country.

Its counties of Los Angeles, Orange, San Diego, San Bernardino, and Riverside are in the top 15 most populous counties in the United States and all five are the top 5 most populous counties in California.[3] The region is also home to Los Angeles International Airport, the third-busiest airport in the United States by passenger volume (see World's busiest airports by passenger traffic) and the second by international passenger volume (see Busiest airports in the United States by international passenger traffic); San Diego International Airport the busiest single runway airport in the world; Van Nuys Airport, the world's busiest general aviation airport; major commercial airports at Orange County, Ontario, Burbank and Long Beach; and numerous smaller commercial and general aviation airports. Southern California is also home to the Port of Los Angeles, the United States' busiest commercial port, the adjacent Port of Long Beach, and the Port of San Diego. Also of note in the region is the freeway system, which is the world's busiest. Six of the seven lines of the commuter rail system, Metrolink, run out of Downtown Los Angeles, connecting Los Angeles, Ventura, San Bernardino, Riverside, Orange, and San Diego counties with the other line connecting San Bernardino, Riverside, and Orange counties directly.

University of California, Santa Barbara

The Tech Coast is a moniker that has gained use as a descriptor for the region's diversified technology and industrial base as well as its multitude of prestigious and world-renowned research universities and other public and private institutions. Amongst these include five University of California campuses (Los Angeles (UCLA), Irvine, Riverside, Santa Barbara, and San Diego (UCSD) campuses), 10 California State University campuses (Channel Islands, Dominguez Hills, Fullerton, Long Beach, Los Angeles, Cal Poly, Pomona (Cal Poly Pomona), Northridge (CSUN), San Bernardino, San Diego (SDSU), and San Marcos campuses), as well as private institutions such as Caltech, the University of Southern California (USC), Pepperdine University, Loyola Marymount University, Chapman University, the Claremont Colleges and the University of San Diego (USD).

Southern California is also the entertainment (motion picture, television, and recorded music) capital of the world and is home to Hollywood, the center of the motion picture industry. Headquartered in Southern California are The Walt Disney Company (which also owns ABC), Sony Pictures, Universal, MGM, Paramount Pictures (parent company of Dreamworks), 20th Century Fox and Warner Brothers, and as well as Univision, Activision, and THQ. Southern California is also home to the world's largest adult entertainment industry, located primarily in the San Fernando Valley.

Besides the entertainment industry, Southern California is also home to a large home grown surf and skateboard culture. Companies such as Volcom, Quiksilver, O'Neill clothing division, No Fear, Lost Enterprises, Sector 9,[4] RVCA, Body Glove and Surfline[5] are all headquartered here. Professional skateboarder Tony Hawk, professional surfers Rob Machado, Tim Curran, Bobby Martinez, Pat O'Connell, Dane Reynolds, and Chris Ward, and professional snowboarder Shaun White live in Southern California. Some of the world's legendary surf spots are here as well, including Trestles, Rincon, The Wedge, Huntington Beach, and Malibu, and it is second only to the island of Oahu in terms of famous surf breaks. Some of the world's biggest extreme sports events including the X Games,[6] Boost Mobile Pro,[7] and the U.S. Open of Surfing are all in Southern California. Southern California is also important to the world of yachting. The annual Transpacific Yacht Race, or "Transpac", from Los Angeles to Hawaii, is one of yachting's premier events. The San Diego Yacht Club held the America's Cup, the most prestigious prize in yachting, from 1988 to 1995 and hosted three America's Cup races during that time.

Southern California is home to many sports franchises and sports networks such as Fox Sports Net. Professional teams that are located in the region include the Los Angeles Lakers, Los Angeles Clippers, Los Angeles Dodgers, Los Angeles Angels of Anaheim, San Diego Padres, Los Angeles Kings, Anaheim Ducks, Los Angeles Galaxy, Chivas USA, and San Diego Chargers. Southern California also is home to a number of popular NCAA sports programs, such as the UCLA Bruins, the USC Trojans, and the San Diego State Aztecs.

Northern boundary

California counties below the sixth standard parallel
The famous Andaz West Hollywood Hotel on the Sunset Strip

There is a definition coinciding neatly with county lines using the sixth standard parallel south[8] of Mount Diablo (144 miles south of Mt. Diablo at 35°47′28″N) which forms the northern borders of San Luis Obispo, Kern, and San Bernardino counties as the boundary. However counties most commonly thought of as making up Southern California are Los Angeles, San Diego, Orange, Riverside, Ventura, San Bernardino and Imperial. Urbanized Santa Barbara is also commonly included. San Luis Obispo County and the northern portion of Santa Barbara County are part of the Central Coast and Kern County is part of the Central Valley, therefore they are not generally considered part of Southern California.

Urban landscape

Part of downtown San Bernardino

Southern California consists of a heavily developed urban environment, along with vast arid areas that have been left undeveloped. It is the second-largest urbanized region in the United States, second only to the Washington/Philadelphia/New York/Boston Northeastern Megalopolis. Whereas these cities are dense, with major downtown populations and significant rail and transit systems, much of Southern California is famous for its large, spread-out, suburban communities and use of automobiles and highways. The dominant areas are Los Angeles, Orange County, San Diego, Riverside, and San Bernardino, each of which is the center of its respective metropolitan area, composed of numerous smaller cities and communities.

Traveling south on Interstate 5, the main gap to continued urbanization is Camp Pendleton. The communities along Interstate 15 and Interstate 215 are so inter-related that Temecula has as much connection with SD Metro as it does with the Inland Empire. To the east, the United States Census Bureau considers the San Bernardino and Riverside County areas, Riverside-San Bernardino Area as a separate metropolitan area from Los Angeles County. While many commute to L.A. and Orange Counties, there are some differences in development, as most of San Bernardino and Riverside Counties were developed in the 1980s and 1990s.

Natural landscape

Southern California consists of one of the more varied collections of geologic, topographic, and natural ecosystem landscapes in a diversity outnumbering other major regions in the state and country. The region spans from Pacific Ocean islands, shorelines, beaches, and coastal plains, through the Transverse and Peninsular Ranges with their peaks, into the large and small interior valleys, to the vast Deserts of California.
