The Corruption Index is always controversial. And it's out today.

Transparency International's 2009 Corruption Perceptions Index (CPI) is the world's most credible measure of of domestic, public sector corruption.

The CPI scores countries on a scale of zero to 10, with zero indicating high levels of corruption and 10, low levels. And the most corrupt places in the world are not the most surprising. Unstable governments, often with a legacy of conflict, continue to dominate the bottom rungs of the CPI. Afghanistan and Myanmar share second to last place with a score of 1.4, with Somalia coming in last with a score of 1.1.

The world's most peaceful countries score the best. In the 2010 CPI, Denmark, New Zealand and Singapore tie for first place with scores of 9.3.

The ranking is based on data from country experts and business leaders at 10 independent institutions, including the World Bank, Economist Intelligence Unit and World Economic Forum.

Transparency International says that it has seen improvements in scores
from 2009 to 2010 for Bhutan, Chile, Ecuador, FYR Macedonia, Gambia, Haiti, Jamaica, Kuwait, and Qatar.

The scores of the Czech Republic, Greece, Hungary, Italy, Madagascar, Niger and the United States have all gone down.
