Industries
Southern California has a diverse economy and is one of the largest economies in the United States.

Southern California is famous for tourism and the entertainment industry. Other industries include software, automotive, ports, finance, biomedical, 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.
