###Input: Southern California consists of one Combined Statistical Area, eight Metropolitan Statistical Areas, one international metropolitan area, and multiple metropolitan divisions. The region is home to two extended metropolitan areas that exceed five million in population. These are the Greater Los Angeles Area at 17,786,419, and San Diego–Tijuana at 5,105,768. Of these metropolitan areas, the Los Angeles-Long Beach-Santa Ana metropolitan area, Riverside-San Bernardino-Ontario metropolitan area, and Oxnard-Thousand Oaks-Ventura metropolitan area form Greater Los Angeles; while the El Centro metropolitan area and San Diego-Carlsbad-San Marcos metropolitan area form the Southern Border Region. North of Greater Los Angeles are the Santa Barbara, San Luis Obispo, and Bakersfield metropolitan areas.

Los Angeles (at 3.7 million people) and San Diego (at 1.3 million people), both in southern California, are the two largest cities in all of California (and two of the eight largest cities in the United States). In southern California there are also twelve cities with more than 200,000 residents and 34 cities over 100,000 in population. Many of southern California's most developed cities lie along or in close proximity to the coast, with the exception of San Bernardino and Riverside.

Southern California's economy is diverse and one of the largest in the United States. It is dominated and heavily dependent upon abundance of petroleum, as opposed to other regions where automobiles not nearly as dominant, the vast majority of transport runs on this fuel. Southern California is famous for tourism and Hollywood (film, television, and music). Other industries include software, automotive, ports, finance, tourism, biomedical, and regional logistics. The region was a leader in the housing bubble 2001–2007, and has been heavily impacted by the housing crash.

Since the 1920s, motion pictures, petroleum and aircraft manufacturing have been major industries. In one of the richest agricultural regions in the U.S., cattle and citrus were major industries until farmlands were turned into suburbs. Although military spending cutbacks have had an impact, aerospace continues to be a major factor.

Southern California is home to many major business districts. Central business districts (CBD) include Downtown Los Angeles, Downtown San Diego, Downtown San Bernardino, Downtown Bakersfield, South Coast Metro and Downtown Riverside.
