military spending as a percentage of GDP

Military spending as a percentage of GDP measures how much of a country's total economic output is allocated to defense. It helps compare how different countries prioritize military activities relative to their overall economy. For example, if a nation spends 3% of its GDP on defense, it means that for every $100 the economy produces, $3 is dedicated to military expenses. This metric accounts for economic size, making it useful for assessing whether a country's defense budget is proportionally high or low compared to its economic capacity. It varies based on strategic needs, economic strength, and policy choices.
