The geographical boundaries of Silicon Valley have changed over the years. Historically, the term Silicon Valley was treated as synonymous with Santa Clara Valley,<ref name="Malone_Page_xix"/><ref name="Matthews_Page_2"/><ref name="Shueh_Page_8"/> and then its meaning later evolved to refer to Santa Clara County plus adjacent regions in southern San Mateo County and southern Alameda County.<ref name=":1">{{Cite news |url=https://www.mercurynews.com/2012/04/19/obrien-welcome-to-the-new-and-expanded-silicon-valley/ |title=Welcome to the new and expanded Silicon Valley |last=O'Brien |first=Chris |date=April 19, 2012 |work=The Mercury News |access-date=April 10, 2018 |language=en-US |quote=After years of drawing a sharp circle that included Santa Clara County as well as southern San Mateo and Alameda counties, this newspaper is expanding the geographic boundaries that it considers to be part of Silicon Valley to include the five core Bay Area counties: Santa Clara, San Mateo, San Francisco, Alameda and Contra Costa. |archive-url=https://web.archive.org/web/20180410201732/https://www.mercurynews.com/2012/04/19/obrien-welcome-to-the-new-and-expanded-silicon-valley/ |archive-date=April 10, 2018 |url-status=live}}</ref> However, over the years this geographical area has been expanded to include San Francisco County, Contra Costa County, and the northern parts of Alameda County and San Mateo County, this shift has occurred due to the expansion in the local economy and the development of new technologies.<ref name=":1" />

The [[United States Department of Labor]]'s [[Quarterly Census of Employment and Wages]] program defined Silicon Valley as the counties of Alameda, Contra Costa, San Francisco, San Mateo, Santa Clara, and Santa Cruz.<ref>{{Cite web |url=https://www.bls.gov/opub/ted/2009/ted_20090908.htm |title=High-tech employment in Silicon Valley, 2001 and 2008 |date=September 8, 2009 |website=U.S. Bureau of Labor Statistics |language=en-us |access-date=April 10, 2018 |quote=In this analysis, Silicon Valley is defined as Alameda, Contra Costa, San Francisco, San Mateo, Santa Clara, and Santa Cruz counties, in California. |archive-url=https://web.archive.org/web/20180410143518/https://www.bls.gov/opub/ted/2009/ted_20090908.htm |archive-date=April 10, 2018 |url-status=live}}</ref> In 2015, MIT researchers developed a novel method for measuring which towns are home to startups with higher growth potential and this defines Silicon Valley to center on the municipalities of Menlo Park, Mountain View, Palo Alto, and Sunnyvale.<ref>{{Cite web |last1=Guzman |first1=Jorge |last2=Stern |first2=Scott |date=September 2014 |title=Nowcasting and Placecasting Growth Entrepreneurship |url=https://ilp.mit.edu/images/conferences/2014/machine/presentations/Stern.2014.2MA.pdf |url-status=dead |archive-url=https://web.archive.org/web/20160304052811/http://ilp.mit.edu/images/conferences/2014/machine/presentations/Stern.2014.2MA.pdf |archive-date=March 4, 2016 |access-date=December 21, 2022 |website=MIT Industrial Liaison Program |publisher=[[MIT]]}}</ref><ref>{{Cite journal |last1=Guzman |first1=Jorge |last2=Stern |first2=Scott |date=February 6, 2015 |title=Where is Silicon Valley? |url=https://www.science.org/doi/10.1126/science.aaa0201 |journal=Science |language=en |volume=347 |issue=6222 |pages=606–609 |doi=10.1126/science.aaa0201 |issn=0036-8075 |pmid=25657229 |bibcode=2015Sci...347..606G |s2cid=206632492 }}</ref>
