The Transparency International Corruption Perceptions Index measures the perceived levels of public-sector corruption in a given country and is a composite index, drawing on different expert and business surveys. The 2008 CPI scores 180 countries (the same number as the 2007 CPI) on a scale from zero (highly corrupt) to ten (highly clean).
Denmark, New Zealand and Sweden share the highest score at 9.3, followed immediately by Singapore at 9.2. Bringing up the rear is Somalia at 1.0, slightly trailing Iraq and Myanmar at 1.3 and Haiti at 1.4.
The continuing high levels of corruption and poverty plaguing many of the world’s societies amount to an ongoing humanitarian disaster and cannot be tolerated."
