The most populous state in the United States, California is also the most popular destination for new immigrants. It is well known for its Hollywood film productions, Silicon Valley technology corporations, and numerous popular tourist destinations. The strength of the Californian economy resides not only in its sheer size, but also in the diversity of industries such as agriculture, manufacturing, biotechnology, aerospace-defense, and tourism. This eclectic range of industries is supported by California’s endowment of natural resources including timber, petroleum, and natural gas. California is the number one travel destination in the United States, featuring Disney theme parks, Pacific Ocean beaches, and eight of the 50 largest cities in the country.
