Some of the biggest drivers of this increase were the US, China, and India while Russian defense spending declined.
"The increase in US spending was driven by the implementation from 2017 of new arms procurement programs under the Trump administration," Aude Fleurant, director of SIPRI's Arms and Military Expenditure (AMEX) program, said in a Monday statement. US defense spending increased by 4.6% in 2018 compared to the year prior.
China's military spending has continued to increase as well, 2018 being the 24th consecutive year of Beijing's budget increasing, putting it in second place worldwide, and along with the US, accounting for roughly half of global military spending.
India's massive modernization of its military helped catapult it to the fourth slot, while Russia's contracting defense budget saw it slip to number 6 worldwide, having declined by 3.5 percent as compared to 2017.
Globally, the average spending was $239 per human on the planet.
