About the Index
The Corruption Perceptions Index (CPI) is published annually by Transparency International (TI), a Berlin-based anti-corruption NGO founded in 1993 by Peter Eigen. First released in 1995, the CPI ranks countries by their perceived levels of public sector corruption, as determined by expert assessments and opinion surveys.
Methodology
- Scale: 0 (highly corrupt) to 100 (very clean)
- Data sources: 13 surveys and expert assessments from 12 independent institutions, including the World Bank, World Economic Forum, and African Development Bank
- Minimum requirement: A country must have data from at least 3 sources to be included
- What it measures: Perceptions of corruption in the public sector only — it does not measure private sector corruption, money laundering, or illicit financial flows
