Transparency International has published the Corruption Perceptions Index (CPI) since 1996, annually ranking countries “by their perceived levels of corruption, as determined by expert assessments and opinion surveys.” The CPI generally defines corruption as “the misuse of public power for private benefit.”
The CPI currently ranks 168 countries “on a scale from 100 (very clean) to 0 (highly corrupt). Countries must be assessed by at least three sources to appear in the CPI.
