Summary
Silicon Valley, located in the southern San Francisco Bay Area and roughly corresponding to the Santa Clara Valley, is a global hub for high technology and innovation. This region, encompassing cities like San Jose, Sunnyvale, Mountain View, Palo Alto, and Menlo Park, is renowned as the birthplace of crucial technologies such as the silicon-based integrated circuit, the microprocessor, and the microcomputer. As of 2021, Silicon Valley was home to the headquarters of over 30 Fortune 1000 companies and thousands of startups, attracting one-third of all venture capital investment in the United States and employing approximately half a million IT workers. The San Jose Metropolitan Area boasts the third-highest GDP per capita globally and, as of June 2021, had the highest percentage of homes valued at over $1 million in the U.S. The term "Silicon Valley" has evolved to refer not only to its core geographic area in Santa Clara and southeastern San Mateo counties but also metonymically to the broader high-tech businesses across the entire Bay Area, and even as a synecdoche for the American high-technology economic sector. The region's success has inspired similar technology centers worldwide, and many of its tech company headquarters are now tourist attractions. More recently, the region has faced challenges related to water security due to intensifying droughts in California.

Silicon Valley is a region in Northern California that is a global center for high technology and innovation. Located in the southern part of the San Francisco Bay Area, it corresponds roughly to the geographical area of the Santa Clara Valley. The term "Silicon Valley" refers to the area in which high-tech business has proliferated in Northern California, and it also serves as a general metonym for California's high-tech business sector. The cities of Sunnyvale, Mountain View, Palo Alto and Menlo Park are frequently cited as the birthplace of Silicon Valley. Other major Silicon Valley cities are San Jose, Santa Clara, Redwood City and Cupertino. The San Jose Metropolitan Area has the third-highest GDP per capita in the world (after Zürich, Switzerland, and Oslo, Norway), according to the Brookings Institution. As of June 2021, it also had the highest percentage of homes valued at $1 million or more in the United States. Silicon Valley is home to many of the world's largest high-tech corporations, including the headquarters of more than 30 businesses in the Fortune 1000, and thousands of startup companies. Silicon Valley also accounts for one-third of all of the venture capital investment in the United States, which has helped it to become a leading hub and startup ecosystem for high-tech innovation, although the tech ecosystem has recently become more geographically dispersed. It was in Silicon Valley that the silicon-based integrated circuit, the microprocessor, and the microcomputer, among other technologies, were developed. As of 2021, the region employed about a half million information technology workers. As more high-tech companies were established across San Jose and the Santa Clara Valley, and then north towards the Bay Area's two other major cities, San Francisco and Oakland, the term "Silicon Valley" came to have two definitions: a narrower geographic one, referring to Santa Clara County and southeastern San Mateo County, and a metonymical definition referring to high-tech businesses in the entire Bay Area. The term Silicon Valley is often used as a synecdoche for the American high-technology economic sector. The name also became a global synonym for leading high-tech research and enterprises, and thus inspired similarly named locations, as well as research parks and technology centers with comparable structures all around the world. Many headquarters of tech companies in Silicon Valley have become hotspots for tourism.
