Understanding global military expenditure | Number Theory

World military expenditure has touched a record high, rising sharply amid wars, geopolitical tensions, and a renewed global arms race. In 2024, global military spending grew 9.4% in real terms to reach $2.7 trillion, according to the “Trends in World Military Expenditure 2024” report released by the Stockholm International Peace Research Institute (SIPRI). This is the highest amount ever recorded, and the sharpest year-on-year increase since at least 1988.
