The four least-corrupt countries in the world are Denmark, New Zealand, Finland and Sweden, according to the 2012 Corruption Perceptions Index, just released by Transparency International.

The index, which is the most widely used corruption indicator, ranks countries based on how corrupt their administrative and political institutions are perceived to be. Each country gets a score between 0 and 100, with 0 indicating the most corrupt and 100 meaning a cleanly run government.

The United States ranked 19th of the 177 countries included in the rankings, and scored 73, the same score it received in 2012.

Somalia, North Korea, Afghanistan and Sudan were seen as having the most corrupt governments in the world.
