The GFP ranking makes use of over 40 factors to determine each nation's Power Index ("PwrIndx") score. From this score, the finalized ranking is generated. The factors are set within our algorithm which provides a fair canvas and allows smaller, yet-technologically advanced nations to compete with larger, lesser-developed ones. Additionally, various bonuses and penalties are added for final refinement. In the end, we hope it presents an unbiased ranking and realistic outlook on the conventional military firepower and strength of a given country for a given year. At the very least, this list can be used to stir healthy debate amongst visitors to GFP.
There are a total of (11) countries of South America represented in the GFP database.
