How is the Corruption Perceptions Index (CPI) score determined?
Public NGO Transparency International’s Corruption Perceptions Index (CPI) is compiled by monitoring and reporting on corruption worldwide.
The CPI measures perceived levels of public sector corruption across 180 countries, using data from institutions like the World Bank, World Economic Forum, and private risk consultancies.
Each country receives a score from 0 to 100 with 0 being highly corrupt and 100 is very clean. The CPI is updated annually, making it one of the most widely used tools to compare corruption levels worldwide.
Countries like Denmark, Finland, and New Zealand tend to lead the global rankings. These nations consistently score high for clean public sectors, effective anti-corruption laws, and trust in government.
