What place does the military hold in the world economy? Statistical snapshots from 2022 on world military spending and arms trade, and then three cautions about the data:
World defense spending at modern-history lows: A widely-used calculation by the Stockholm International Peace Research Institute (SIPRI) finds world military spending — procurement, pay, military construction, and so on — at about $2.24 trillion in 2022. According to the International Monetary Fund, world GDP was $100.15 trillion that year. So SIPRI’s figure suggests that about 2.2% of world income went to military budgets, and a World Bank table for the same year yields a very close 2.3% of world GDP.
This figure captures the policies governments set down in 2021, just before the Russian invasion of Ukraine, and by historical standards, it is very low. Tallies from earlier decades report military spending rates above 6% of world GDP in the 1960s; in a range from 3.8% to 4.5% in the 1970s and 1980s; and varying since 2000 in a narrow band between 2.2% and 2.6%. As two points of comparison: (a) about 11% of world GDP goes to health (or 6% of world GDP if one counts only public spending), and 4.2% to education; and (b) in labor terms, the CIA’s World Factbook estimates that about 20 million men and women are in uniform around the world which would be 0.5% of the world’s 3.5 billion workers. To look more specifically at the U.S., American military spending was about 3.5% of GDP in 2022 (by the World Bank’s table), which is above the worldwide average but far below the 11% the U.S. Defense Department reports for the Korean War years in the early 1950s and the 5% levels of the later Cold War.
Arms trade small relative to civilian trade: SIPRI’s parallel “arms transfer” count reports about $32 billion worth of arms deliveries in 2022. Their count covers deliveries of “major conventional weapons” — tanks, planes, missiles, submarines, artillery, etc. — and includes sales of both new and used kits, licensed production, and deliveries of significant components as well as complete systems. Like the world’s combined military budget as a share of GDP, the arms transfer total is a lot of money but small when measured against civilian trade. The WTO’s most recent annual trade statistics report puts “goods trade” in general at $24 trillion in 2022, which would make SIPRI’s $32 billion in arms transfers about 0.1% of the total. Or, to look at particular products, the WTO’s places clothing exports at $313 billion — ten times SIPRI’s arms transfer figure — and automotive trade at a much larger $1.37 trillion, while the U.N. Food and Agricultural Organization’s estimate of fish and seafood exports was $151 billion.
Nor does military trade look very large for individual countries. By country, SIPRI’s top exporters in 2022 were the U.S. at $14.5 billion, France at $3.0 billion, Russia at $2.8 billion, and China at $2.0 billion. This would be about 1% of the U.S.’ $2.1 trillion in goods exports, 0.5% of French and Russian exports (though a higher 3% of Russian manufacturing trade), and 0.1% of Chinese exports. On the import side, military shares of trade can be quite high for the largest purchasers — Qatar, the largest buyer on the SIPRI list, spent $3.3 billion on weapons or 15% of its overall $28 billion in imports, and military goods accounted for 2% and 7% of imports for fourth place Saudi Arabia and fifth place Kuwait — but outside the Persian Gulf is rarely a very large part of national import bills.
Tentative Conclusion: The public data and estimates, then, suggest that as of 2022 the world’s military economy was a relatively small part of the larger global economy; military spending a modest though not tiny part of national budgets; and military trade a very small part of international trade. Three cautions, though:
Caution (1): Secrecy: In many countries, some sections of national defense budgets and arms sales aren’t thought suitable for publishing, and are thus missing from the totals. So figures for military spending and trade, strictly defined, are reasonable “lowest-case estimates” rather than very firm data.
Caution (2): Definitions: The military economy is not separate from the civilian economy, but merges with it along the edges. Definitions of what is “military” and what is “civilian” are thus a bit arbitrary. In military trade, for example, is the right approach SIPRI’s decision to count weapons only? Would it be better to add “dual-capable” trucks, chips, fuel, rifles, and satellites too? Repair, training, software updates, replacement parts, and maintenance? Or should everything a military service buys be considered “arms trade”?
As an important example, the U.S. Defense Department’s 2023 policy paper observes that for both of these reasons, China’s “actual military-related spending could be 1.1 to 2 times higher than stated in its official [$209 billion] budget.” This would suggest a figure approaching $400 billion and somewhere between 2% and 3.2% of Chinese GDP, in contrast to the World Bank table’s 1.6%. (And some private estimates go higher.) Or to choose a case close to home, the State Department’s Political-Military Affairs branch, which oversees official U.S. arms sales policy, uses a broader definition than SIPRI’s to report “new sales” of U.S. weapons at about $55 billion a year, which would imply considerably higher global as well as American arms sales.
Caution (3): Changing times: The defense budgets and arms transfers of 2022 are those decided upon in 2021, just before Russia’s attack on Ukraine. Whatever the definitions one chooses, and however much they publish, governments are making this year’s budgets and sales in a world grown more dangerous, and their numbers will presumably be larger.

U.S. policy:
Secretary of Defense Lloyd Austin, presenting an $842 billion request for next year’s defense budget to the Armed Services Committees, notes (a) a “pacing challenge” from rising military spending and capability in China; (b) an “acute threat” to Europe and global security posed by Russia’s invasion of Ukraine; and (c) structural programs including pay raises for enlisted personnel, research and development, and more.

Spending:
A World Bank table of military spending/GDP makes Latin America and the Pacific Islands the regions with the least ambitious military budgets, at an average of 1.0% for each region. The Arab states’ spending level is highest at 5.0%. The sample below drops two outliers at the very top — Eritrea’s 20.5% of GDP as of 2003, and Libya’s 15.5% as of 2014 — along with embattled Ukraine’s 33.5%. (Also note, the Bank doesn’t venture a guess for North Korea.) Apart from these anomalies, military spending/GDP ratios around the world in 2022 topped out at Saudi Arabia’s 7.4% and Qatar’s 7.0%, and drift downward to the 0.2% levels for Laos, Mauritius, and Ireland, and Haiti’s lowest-in-the-world 0.1%. Here’s a sample list indicating the range.
Saudi Arabia | 7.4% |
Qatar | 7.0% |
Oman | 5.2% |
Israel | 4.5% |
Russia | 4.1% |
U.S. | 3.5% |
Cuba | 2.9% |
Singapore | 2.8% |
South Korea | 2.7% |
Pakistan | 2.6% |
Lithuania | 2.5% |
WORLD | 2.3% |
Vietnam | 2.3% |
United Kingdom | 2.2% |
France | 1.9% |
China* | 1.6% |
Norway | 1.6% |
Spain | 1.5% |
New Zealand | 1.2% |
Thailand | 1.2% |
Brazil | 1.1% |
Switzerland | 0.8% |
Indonesia | 0.7% |
South Africa | 0.7% |
Argentina | 0.4% |
Ireland | 0.2% |
Haiti | 0.1% |
* Official published Chinese budget. At the high end of DoD’s range, the Chinese military share of GDP share would be 3.2%, about the same as that of the United States.
And some perspectives on China’s military spending:
SIPRI’s $240 billion in 2019.
DoD’s view (p. 142) has 1.1 to 2.0 times higher than the public budget, for a range between $220 billion and $420 billion.
And the American Enterprise Institute, citing Alaska Sen. Dan Sullivan, guesses $700 billion.
