Global Corruption Barometer (GCB)
Transparency International's Global Corruption Barometer is the only worldwide public opinion survey on views and experiences of corruption. As a poll of the general public, it provides an indicator of how corruption is affecting individuals on a national level and how efforts to curb corruption around the world are viewed on the ground.
The Barometer includes a variety of corruption-related questions including which domestic institutions are seen as most corrupt and how respondents rate their government in the fight against corruption. It also provides insight on people's experiences with bribery, gathering information on how frequently citizens were asked to pay bribes when interacting with different public services.
Most national surveys were carried out on behalf of TI by Gallup International, as a specially commissioned part of its 'Voice of the People Survey'. Gallup draws on its in-country affiliates to translate and carry out its contribution to the Barometer.
