Southern California

===Industries===
Southern California has a diverse economy and is one of the largest economies in the United States. It is dominated by and heavily dependent upon the abundance of petroleum, as opposed to other regions where automobiles are not nearly as dominant, due to the vast majority of transport that runs on this fuel. Southern California is famous for tourism and the [[entertainment industry]]. Other industries include software, automotive, aerospace, finance, biomedical, ports and regional logistics. The region was a leader in the housing bubble from 2001 to 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.<ref>{{cite book|editor-last=Westwick|editor-first=Peter J.|date=June 4, 2012|title=Blue Sky Metropolis|location=[[Huntington Library]]|publisher=University of California Press|url=https://books.google.com/books?id=O5IkDQAAQBAJ|isbn=978-0-52028-906-2|access-date=May 9, 2021|archive-date=March 15, 2023|archive-url=https://web.archive.org/web/20230315184948/https://books.google.com/books?id=O5IkDQAAQBAJ|url-status=live}}</ref>
