Corruption Perceptions Index 2011

The Corruptions Perception Index 2011 was launched on 1st December 2011.


Transparency International's Corruption Perceptions Index 2011 shows that Ireland’s ranking has fallen and it now compares poorly to other northern European nations.

The CPI 2011 ranks 183 countries by their perceived levels of public sector corruption. Ireland ranks 19 out of 183 countries with a score of 7.5 out of ten. Last year Ireland held 14th position with a score of 8. The  scores range from 0 (highly corrupt) to 10 (very clean).

The CPI measures perceptions of business people and experts of corruption in the public sector including corruption involving public officials, civil servants or politicians.
