Military expenditure figures, presented in different ways, have a variety of uses, including the measurement of the economic burden of these expenditures and the assessment of the trend in a nation's military strength. Moreover, the international comparison of military expenditures influences opinion about how much should be spent in the future. And, in military alliances, the relative economic burden of these expenditures between member nations is a frequently discussed, and often contentious, issue.
This report investigates the limitations of the military expenditure data widely employed in these various ways.
