Useful Stats: Sources of Private R&D Funding by State, 2012
California-based companies performed about $81.7 billion in research and development (R&D) in 2012, according to the latest data available from the National Science Foundation (NSF). That figure represents about 27 percent of all private R&D funding in the U.S. Not all of that funding, however, derived from the companies themselves. The federal government provided about 9.3 percent of the funds for California-based company R&D in 2012.
