The Corruption Perception Index (CPI) is issued annually by Berlin-based Transparency International and ranks countries on a scale of zero to ten according to their perceived levels of corruption, with a higher score indicating less perceived corruption.
While Sweden’s overall score of 9.3 matched the mark it achieved in the 2007 edition of the survey, a fall by neighboring Finland opened up a spot at the top of this year’s ranking, along with Denmark and New Zealand.
The top-ranking trio from the 2008 survey is followed immediately in the index by Singapore at 9.2, with Finland and Switzerland coming next with scores of 9.0.
Iceland achieved a score of 8.9, while Norway ranked lowest of all the Scandinavian countries with a score of 7.9.
The CPI is a composite index, which aggregates results published in different expert and business surveys about countries’ perceived level of corruption.
The lowest ranked country in this year’s index is Somalia at 1.0.
Ranking slightly better, are Iraq and Myanmar at 1.3, followed by Haiti at 1.4.
