We asked over 114,000 people in 107 countries for their views on corruption. 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.
The Global Corruption Barometer 2013 is the biggest ever survey tracking worldwide public opinion on corruption. It addresses people’s direct experiences with bribery and details their views on corruption in the main institutions in their countries. It also provides insights into people's willingness to stop corruption.
