Corruption Perceptions Index 2010

With governments committing huge sums to tackle the world's most pressing problems, from the instability of financial markets to climate change and poverty, corruption remains an obstacle to achieving much needed progress.

The 2010 Corruption Perceptions Index shows that nearly three quarters of the 178 countries in the index score below five, on a scale from 10 (highly clean) to 0 (highly corrupt). The most corrupted country is Somalia. The least corrupted countries are Denmark, New Zealand, and Singapore.
