World Military expenditures - dollar figure

Military expenditures - dollar figure: aggregate real expenditure on arms worldwide has increased in the beginning of the 21st century, with the largest increase in the US; a rough estimate for 2005 is $1.2 trillion (at puchasing power parity) (2005 est.)

Definition: This entry gives current military expenditures in US dollars; the figure is calculated by multiplying the estimated defense spending in percentage terms by the gross domestic product (GDP) calculated on an exchange rate basis, not purchasing power parity (PPP) terms.  Dollar figures for military expenditures should be treated with caution because of different price patterns and accounting methods among nations, as well as wide variations in the strength of their currencies.
