Corruption Perceptions Index 2006

CPI 2006 map graphic

Today’s results indicate that much remains to be done before we see meaningful improvements in the lives of the world’s poorest citizens."

– Huguette Labelle, Chair of Transparency International

The 2006 Corruption Perceptions Index is a composite index that draws on multiple expert opinion surveys that poll perceptions of public sector corruption in 163 countries around the world, the greatest scope of any CPI to date. It scores countries on a scale from zero to ten, with zero indicating high levels of perceived corruption and ten indicating low levels of perceived corruption.

A strong correlation between corruption and poverty is evident in the results of the CPI 2006. Almost three-quarters of the countries in the CPI score below five (including all low-income countries and all but two African states) indicating that most countries in the world face serious perceived levels of domestic corruption. Seventyone countries - nearly half - score below three, indicating that corruption is perceived as rampant. Haiti has the lowest score at 1.8; Guinea, Iraq and Myanmar share the penultimate slot, each with a score of 1.9. Finland, Iceland and New Zealand share the top score of 9.6.

Background information

  • CPI Score relates to perceptions of the degree of corruption as seen by business people and country analysts, and ranges between 10 (highly clean) and 0 (highly corrupt).
  • Confidence range provides a range of possible values of the CPI score. This reflects how a country's score may vary, depending on measurement precision. Nominally, with 5 percent probability the score is above this range and with another 5 percent it is below. However, particularly when only few sources are available, an unbiased estimate of the mean coverage probability is lower than the nominal value of 90%.
  • Surveys used refers to the number of surveys that assessed a country's performance. 12 surveys and expert assessments were used and at least 3 were required for a country to be included in the CPI.
