Corruption Perceptions Index 2019: Overview of 180 countries

According to the 2019 Corruption Perceptions Index (CPI) released by Transparency International, more than two-thirds of countries – along with many of the world’s most advanced economies – are stagnating or showing signs of backsliding in their anti-corruption efforts.

Countries in which elections and political party financing are open to undue influence from vested interests are less able to combat corruption, analysis of the results finds.

“Frustration with government corruption and lack of trust in institutions speaks to a need for greater political integrity,” said Delia Ferreira Rubio, Chair of Transparency International.

Corruption Perceptions Index - Highlights

The CPI ranks 180 countries and territories by their perceived levels of public sector corruption, drawing on 13 expert assessments and surveys of business executives. It uses a scale of zero (highly corrupt) to 100 (very clean).

More than two-thirds of countries score below 50, with an average score of only 43. Since 2012, only 22 countries have significantly improved their scores, including Estonia, Greece and Guyana. Twenty-one have significantly declined, including Australia, Canada and Nicaragua.

The research of Transparency International shows several of the most advanced economies cannot afford to be complacent if they are to keep up their anti-corruption momentum. Four G7 countries score lower than last year: Canada (-4), France (-3), the UK (-3) and the US (-2). Germany and Japan have seen no improvement, while Italy gained one point.

Corruption and political integrity

The analysis also shows that countries that perform well on the CPI also have stronger enforcement of campaign finance regulations and broader range of political consultation. Countries where campaign finance regulations are comprehensive and systematically enforced have an average score of 70 on the CPI, whereas countries where such regulations either don’t exist or are poorly enforced score an average of just 34 and 35 respectively.
