JRC helps measuring corruption perception

Dec 10 2012

The JRC has provided a thorough statistical analysis for the 2012 corruption perceptions index, issued by Transparency International on 5 December.

Upon request of Transparency International, and due to its renowned expertise in composite indicators, the JRC has assessed for the first time the methodology used, which was revised this year to provide greater clarity on how the different data are incorporated into the ranking. According to the JRC's analysis, the new methodology is conceptually and statistically coherent and has a balanced structure.

The corruption perceptions index is a composite indicator that measures perceptions of corruption in the public sector in different countries around the world. Since it's launch in 1995, it has been widely credited with putting the issue of public sector corruption (i.e. administrative and political corruption) on the international policy agenda.

The world's most perceived as corrupt countries in 2012 are Afghanistan, North Korea and Somalia, on an equal footing. In the EU, the worst perceived country in terms of corruption is Greece. On the other end, two European countries (Denmark and Finland) together with New Zealand, rank first as being perceived as the least corrupt.

The JRC also supports the World Justice Project's rule of law index since 2009, by analysing the multi-dimensional structure used (which covers issues such as government power or civil justice) and making sure that it is statistically coherent and balanced. The rule of law index offers a detailed and comprehensive picture of the extent to which countries adhere to the rule of law in practice.
