context_page_description: The economy of the United States is that of a developed country with a mixed economy. It is the world's largest economy by nominal GDP and net wealth and the second-largest by purchasing power parity. It has the world's eighth-highest per capita GDP and the tenth-highest per capita GDP in 2019. The United States has the most technologically powerful economy in the world and its firms are at or near the forefront in technological advances, especially in computers, pharmaceuticals, and medical, aerospace, and military equipment. The U.S. dollar is the currency most used in international transactions and is the world's foremost reserve currency, backed by its economy, its military, the petrodollar system and its linked eurodollar and large U.S. treasuries market. Several countries use it as their official currency and in others it is the de facto currency. The largest U.S. trading partners are China, Canada, Mexico, Japan, Germany, South Korea, United Kingdom, France, India, and Taiwan. The U.S. is the world's largest importer and the second-largest exporter.
context_section_description: The level of research spending varies considerably from one state to another. Six states (New Mexico, Maryland, Massachusetts, Washington, California and Michigan) each devoted 3.9% or more of their GDP to R&D in 2010, together contributing 42% of national research expenditure. In 2010, more than one quarter of R&D was concentrated in California (28.1%), ahead of Massachusetts (5.7%), New Jersey (5.6%), Washington State (5.5%), Michigan (5.4%), Texas (5.2%), Illinois (4.8%), New York (3.6%) and Pennsylvania (3.5%). Seven states (Arkansas, Nevada, Oklahoma, Louisiana, South Dakota and Wyoming) devoted less than 0.8% of GDP to R&D.
  California is home to Silicon Valley, the name given to the area hosting the leading corporations and start-ups in information technology. This state also hosts dynamic biotechnology clusters in the San Francisco Bay Area, Los Angeles and San Diego. The main biotechnology clusters outside California are the cities of Boston/Cambridge, Massachusetts, Maryland, suburban Washington, DC, New York, Seattle, Philadelphia, and Chicago. California supplies 13.7% of all jobs in science and engineering across the country, more than any other state. Some 5.7% of Californians are employed in these fields. This high share reflects a potent combination of academic excellence and a strong business focus on R&D: the prestigious Stanford University and University of California rub shoulders with Silicon Valley, for instance. In much the same way, Route 128 around Boston in the state of Massachusetts is not only home to numerous high-tech firms and corporations but also hosts the renowned Harvard University and Massachusetts Institute of Technology.
  New Mexico's high research intensity can be explained by the fact that it hosts the Los Alamos National Laboratory. Maryland's position may reflect the concentration of federally funded research institutions there. Washington State has a high concentration of high-tech firms like Microsoft, Amazon and Boeing and the engineering functions of most automobile manufacturers are located in the state of Michigan.
