Corruption Perceptions Index

What is the Corruption Perceptions Index (CPI)?

The Index  ranks countries "by their perceived levels of public sector corruption, as determined by expert assessments and opinion surveys." The CPI generally defines corruption as an "abuse of entrusted power for private gain"

 

Who created the Index?

The index is published annually by the non-governmental organisation Transparency International since 1995. The 2022 CPI, published in January 2023, currently ranks 180 countries "on a scale from 100 (very clean) to 0 (highly corrupt)". Transparency International commissioned the University of Passau's Johann Graf Lambsdorff to produce the CPI. Early CPIs used public opinion surveys.

 

What are the ranking factors in the Index CPI?

Ranking factor for Index is misuse of government power for private gain.

The 2022 CPI, published in January 2023, currently ranks 180 countries "on a scale from 100 (very clean) to 0 (highly corrupt)" from 12 different institutions. The institutions are:

• African Development Bank (based in Côte d'Ivoire)
• Bertelsmann Foundation (based in Germany)
• Economist Intelligence Unit (based in the UK)
• Freedom House (based in the US)
• Global Insight (based in the US)
• International Institute for Management Development (based in Switzerland)
• Political and Economic Risk Consultancy (based in Hong Kong)
• The PRS Group, Inc., (based in the US)
• World Bank
• World Economic Forum
• World Justice Project (based in the US)

Countries need to be evaluated by at least three sources to appear in the CPI. The CPI measures perception of corruption due to the difficulty of measuring absolute levels of corruption.
