Portal:Greater Los Angeles/Intro
The Greater Los Angeles Area, or the Southland, is a term used for both the urbanized region and Combined Statistical Area (a group of interacting metropolitan areas) sprawling over five counties in the southern part of California, namely Los Angeles, Orange, San Bernardino, Riverside, and Ventura counties. Throughout the 20th century, it was one of the fastest-growing regions in the United States, although growth has slowed since 2000. As of the 2010 U.S. Census, the Los Angeles metropolitan area had a population of about 12.8 million residents. Meanwhile, the larger metropolitan region's population at the 2010 census was estimated to be over 17.8 million residents, and a 2011 estimate reported a population of about 18.1 million. Either definition makes it the second largest metropolitan region in the country, behind the New York metropolitan area, as well as one of the largest urban agglomerations in the world.
The agglomeration of the urbanized Greater Los Angeles area surrounds the urban core of Los Angeles County. The regional term is defined to refer to the more-or-less continuously urbanized area stretching from Ventura County to the southern border of Orange County and from the Pacific Ocean to the Coachella Valley in the Inland Empire. The US Census Bureau defines the Greater Los Angeles area to include the entire Los Angeles county, Ventura County, Orange County and the two counties of the Inland Empire, making up the "Los Angeles-Long Beach-Riverside, CA" Combined Statistical Area. However this Census definition includes large, sparsely populated and primarily desert swaths of Los Angeles, San Bernardino and Riverside counties that are not part of the urbanized region. The term "Greater Los Angeles" does not include San Diego and Imperial counties, whose urbanized areas are not geographically continuous with the urbanized area surrounding Los Angeles.
