Research and development (R&D) spending was forecast to reach over 2.47 trillion U.S. dollars globally in 2022 (once local currencies are converted for purchasing power parity). This compares to around one trillion U.S. dollars in 2005, and around 555 billion U.S. dollars in 1996. Spending decreased somewhat in 2020 following the outbreak of COVID-19, but increased again in 2021 and was forecast to do so in 2022 too.
