The 2018 Corruption Perceptions Index, published by Transparency International, measures the perceived levels of public sector corruption in 180 countries and territories. Drawing on 13 surveys of businesspeople and expert assessments, the index scores on a scale of zero (highly corrupt) to 100 (very clean).
The results paint a sadly familiar picture: more than two-thirds of countries score below 50, while the average score is just 43. Perhaps most disturbing is that the vast majority of countries assessed have made little to no progress. Only 20 have made significant progress in recent years.
As long as corruption continues to go largely unchecked, the results show that democracy is under threat around the world.
