Since 1995, Transparency International (TI) publishes the Corruption Perceptions Index (CPI) 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."
As of 2012, the CPI ranks 176 countries "on a scale from 100 (very clean) to 0 (highly corrupt)."
