Corruption Perceptions Index 2025

Transparency International’s 2025 Corruption Perceptions Index (CPI) ranks 182 countries and territories according to the levels of public-sector corruption perceived by experts and businesspeople. It relies on 13 independent data sources and uses a scale of zero to 100, where zero means that the country’s public sector is seen as highly corrupt, and 100 as very clean. The results underline how most countries need to do far more to prevent and stop corruption.

This publication provides the full scores and ranks as well as an overview of the current state of corruption globally alongside recommendations on how to address the problem.

The Changing Corruption Levels section presents insight into several trends that explain long term score changes experienced by different groups of improving and declining countries.

Additionally, the Key Drivers and Consequences of Corruption section explores four important topics that are closely interlinked with corruption:

• justice and the rule of law
• democracy and political integrity
• civic space and media freedom
• public services and inequality
