In detail: Global Corruption Barometer 2013

Transparency International’s Global Corruption Barometer is the largest world-wide public opinion survey on corruption. It addresses people’s direct experiences with bribery and details their views on corruption in the main institutions in their countries. Significantly, the Barometer also provides insights into how willing and ready people are to act to stop corruption.

The 2013 Barometer, the eighth edition, reflects the responses of more than 114,000 people in 107 countries, and offers the greatest country coverage to date.

About the survey

For the Global Corruption Barometer 2013, approximately 1,000 people from each of 107 countries were surveyed between September 2012 and March 2013. Five hundred people were surveyed in countries with a population of less than 1,000,000. The survey sample in each country has been weighted to be nationally representative where possible. In six countries, the sample was urban only.
