It is certainly hard to imagine the world with corruption free, but there are few countries that have diminished the effect of corruption and suppressed it from spreading to the different cities within the country.
Transparency International, a Berlin-based organization has stated that corruption happens every where when politicians and officials demand money and other expensive favours in return for offering a government service that must be actually provided for free.
The Corruption Perceptions Index (CPI) measured the level of corruptions that happens in public sectors of various countries over the globe.
Transparency International provides score for each country that ranges from 0 (highly corrupt) to 100 (very clean). There are few countries that have reached near to 100 but there is no country that has reached 100.
