===Impact of recession on research spending===
Generally speaking, U.S. investment in R&D rose with the economy in the first years of the century before receding slightly during the economic recession then rising again as growth resumed. At its peak in 2009, GERD amounted to US$406{{spaces}}billion (2.82% of GDP). Despite the recession, it was still at 2.79% in 2012 and will slide only marginally to 2.73% in 2013, according to provisional data, and should remain at a similar level in 2014.<ref name=":0" />

The federal government is the primary funder of basic research, at 52.6% in 2012; state governments, universities and other non-profits funded 26%. Experimental development, on the other hand, is primarily funded by industry: 76.4% to the federal government's 22.1% in 2012.<ref name=":0" />

While U.S. investment in R&D is high, it failed to reach President Obama's target of 3% of GDP by the end of his presidency in 2016. Between 2009 and 2012, the United States' world share of research expenditure receded slightly from 30.5% to 28.1%. Several countries now devote more than 4% of GDP to R&D (Israel, Japan and the Republic of Korea) and others plan to raise their own GERD/GDP ratio to 4% by 2020 (Finland and Sweden).<ref name=":0" />
