Why is the Corruption Perceptions Index a valuable tool?
Because the CPI is derived from 15 different surveys that garner the perceptions of both residents and expatriates, both business people and risk analysts, the index provides a snapshot of the views of decision-makers, who take key decisions on investment and trade. The CPI builds public awareness of the corruption issue, and it adds to pressure on governments to directly address the issue and the damaged image of their nation that low rankings in the CPI reflect.
