Based on expert opinion, the Corruption Perceptions Index measures the perceived levels of public sector corruption worldwide.
“Over two-thirds of the 176 countries and territories in this year's index fall below the midpoint of our scale of 0 (highly corrupt) to 100 (very clean). The global average score is a paltry 43, indicating endemic corruption in a country's public sector. Top-scoring countries (yellow in the map below) are far outnumbered by orange and red countries where citizens face the tangible impact of corruption on a daily basis,” Transparency International says.
This year, Sri Lanka has scored 36, which is one point down from last year. The following are the points secured by Sri Lanka in the last five years.
Sri Lanka was ranked No. 83 in the Corruption Perception Index 2015.
The index ranks 176 countries on a scale of zero to 100. In the 2016 index, Somalia is at the bottom of the list, scoring just 10 while Denmark and New Zealand are ranked at the top with a score of 90.
