Annual Military Spending

The chart of this week is a treemap of the military spending around the world. The data is from the Stockholm International Peace Research Institute (SIPRI) Military Expenditure Database which is based on open sources.

🔷 The world military expenditure was $1,981 billion in 2020, an increase of 2.6% on 2019 in real terms.

🔷 The top 5 spenders in 2020 were the United States, China, India, Russia and the United Kingdom, which together accounted for 62% of world military spending.

🔷 Military expenditure by the top 15 countries reached $1,603 billion in 2020 and accounted for 81% of global military spending.

🔷 Note that on February 27, 2022, in response to the ongoing escalation of the Russo-Ukrainian War, Germany announced a extraordinary expenditure bump to 100 billion Euro or 112bn USD, up from 47.31bn Euro or 52.8bn USD, as estimated by SIPRI, putting them at the 3rd largest on the planet.
