Indicator SDG 9.5.1

Research and development expenditure as a proportion of GDP

In 2013, countries invested 1.70% of GDP in research and development, on average, compared to 1.57% of GDP in 2007. Although the G20 accounted for 92% of global research expenditure (and 64% of the global population) in 2013, low-income countries doubled their investment in research and development from $1.9 billion to $3.9 billion (power parity dollars) between 2007 and 2013, carrying their global share of research spending to 0.3% in 2013.
