Subsequently, Californians (dissatisfied with inequitable taxes and land laws) and pro-slavery Southerners in the lightly populated "cow counties" of southern California attempted three times in the 1850s to achieve a separate statehood or territorial status separate from Northern California.

Population

As of the 2020 United States Census, Southern California has a population of 23,762,904. Despite a reputation for high growth rates, Southern California's population has grown slower than the state average since the 2000s. This is due to California's growth becoming concentrated in the northern part of the state as result of a stronger, tech-oriented economy in the Bay Area and an emerging

Literature

Southern California is home to most popular and famous literature in the region. These books include California by Kevin Starr, Malibu Farm Cookbook by Helene Henderson, L.A. Noir by John Buntin, The Mountains of California by John Muir, The New California Wine by Jon Bonné, and My Hollywood by Mona Simpson. Most of them are well received and nominated for rewards.

Economy

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, 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.
