WASHINGTON — Overall military expenditures rose 2.6 percent between 2017 and 2018, to hit a total of $1.82 trillion, according to new research from the Stockholm International Peace Research Institute.

The total from 2018 is 5.4 percent higher than 2009, and represents a 76 percent increase over 1998, a 20-year period.

Sixty percent of global military spending came from five countries: The United States ($649 billion), China ($250 billion), Saudi Arabia ($67.6 billion), India ($66.5 billion) and France ($63.8 billion). Russia ($61.4 billion) and the United Kingdom ($50 billion) were the other two countries to spend $50 billion or more on defense.

However, there are ups and downs among the biggest spenders. While the U.S. (4.6 percent, the first overall growth since 2010), China (5 percent) and India (3.1 percent) increased their respective military spending year over year, Saudi Arabia cut its spending by 6.5 percent, France by 1.4 percent and Russia by 3.5 percent.

And overall defense spending per gross domestic product fell to 2.1 percent in 2018, representing $239 per global citizen, a 0.1 percent decrease over one year and a 0.5 percent decrease over 10 years.

Notably, Russia ranked outside the top five for the first time since 2006. China, meanwhile, increased its military spending for the 24th consecutive year, and its spending is almost 10 times higher than it was in 1994; however, researchers warn that Chinese growth may slow in the coming year.

“The annual rate of growth of China’s military spending has slowed steadily since it reached a post-2009 high of 9.3 percent in 2013. The growth of 5.0 percent in 2018 was the lowest annual increase since 1995,” the authors note. “China has followed a policy of linking growth in military spending with economic growth. With its economic growth slowing in 2018 to the lowest level in 28 years, slower rates of growth in the coming years can be expected if China continues to follow this policy.”
