The Corruption Perceptions Index (CPI) measures the perceived level of public-sector corruption in 180 countries and territories around the world. The CPI is a "survey of surveys", based on 13 different expert and business surveys.

The vast majority of the 180 countries included in the 2009 index score below five on a scale from 0 (perceived to be highly corrupt) to 10 (perceived to have low levels of corruption). The CPI measures the perceived levels of public sector corruption in a given country and is a composite index, drawing on 13 different expert and business surveys. The 2009 edition scores 180 countries, the same number as the 2008 CPI.

Fragile, unstable states that are scarred by war and ongoing conflict linger at the bottom of the index. These are: Somalia, with a score of 1.1, Afghanistan at 1.3, Myanmar at 1.4 and Sudan tied with Iraq at 1.5. These results demonstrate that countries which are perceived as the most corrupt are also those plagued by long-standing conflicts, which have torn apart their governance infrastructure.

Highest scorers in the 2009 CPI are New Zealand at 9.4, Denmark at 9.3, Singapore and Sweden tied at 9.2 and Switzerland at 9.0. These scores reflect political stability, long-established conflict of interest regulations and solid, functioning public institutions.

Overall results in the 2009 index are of great concern because corruption continues to lurk where opacity rules, where institutions still need strengthening and where governments have not implemented anti-corruption legal frameworks.

Globally and nationally, institutions of oversight and legal frameworks that are actually enforced, coupled with smarter, more effective regulation, will ensure lower levels of corruption. This will lead to a much needed increase of trust in public institutions, sustained economic growth and more effective development assistance. Most importantly, it will alleviate the enormous scale of human suffering in the countries that perform most poorly in the Corruption Perceptions Index.
