The World's Most Corrupt Nations, 2010

According to the annual survey by the Berlin-based organization Transparency International, Somalia, Myanmar, Afghanistan, and Iraq are perceived to be the most corrupt, Denmark, New Zealand, Singapore, Finland, and Canada are perceived to be the world's least corrupt countries. For a list of the least corrupt nations, see World's Least Corrupt Countries. The index defines corruption as the abuse of public office for private gain and measures the degree to which corruption is perceived to exist among a country's public officials and politicians. It is a composite index, drawing on 13 different expert and business surveys. Only 178 of the world's 193 countries are included in the survey, due to an absence of reliable data from the remaining countries. The scores range from ten (squeaky clean) to zero (highly corrupt). A score of 5.0 is the number Transparency International considers the borderline figure distinguishing countries that do and do not have a serious corruption problem. In the 2010 survey, 75% scored below five.
