Corruption rankings
Different organizations have their specific methodology for calculating corruption rankings for countries around the world.
The Corruption Perception Index, published by Transparency International, a civil society organization, is one of the most comprehensive, covering 180 countries.
The index ranks countries by perceived levels of public sector corruption, based on opinion polls and expert assessments (archived here). Countries are given a score between 0 (very corrupt) and 100 (very clean).
In the 2023 rankings, Nigeria scored 25 out of 100, while Kenya scored 31 (archived here).
Transparency International ranked Somalia as Africa’s most corrupt country with a score of 11, while Seychelles was named the continent’s least corrupt country at 71.
Between 2019 and 2023, Nigeria and Kenya have not yet scored 50 points, the midpoint of the rankings.
The Political Corruption Index from the Varieties of Democracy Institute, a research institute at Sweden’s University of Gothenburg, also ranks corruption cases highly in Nigeria and Kenya (archived here).
The index uses a score between zero and one. Zero represents a low presence of political corruption and one indicates high political corruption.
In 2023, Nigeria scored 0.92 points, while Kenya scored 0.52 points. The Institute again ranked Seychelles as the least corrupt country in Africa with a score of 0.05 points.
