The World's Least Corrupt Nations, 2011
According to the annual survey by the Berlin-based organization Transparency International, Finland, Denmark, and New Zealand are perceived to be the world's least corrupt countries, and Myanmar, North Korea, and Somalia are perceived to be the most corrupt. For a list of the most corrupt nations, see World's Most 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 183 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 2011 survey, the vast majority scored below five.
