The Corruption Perceptions Index ranks countries and territories based on how corrupt their public sector is perceived to be. A country or territory’s score indicates the perceived level of public sector corruption on a scale of 0 (highly corrupt) to 100 (very clean). A country or territory’s rank indicates its position relative to the other countries and territories in the index.

This year’s index includes 175 countries and territories – http://www.transparency.org/cpi2014/results
