The TI Global Corruption Barometer complements TI’s other main global indicators on corruption, the Corruption Perceptions Index and the Bribe Payers Index, by polling public, rather than expert, opinion on corruption. The Global Corruption Barometer can be used to raise awareness of the extent and impact of corruption, as judged by the general public. Its question targeted at levels of corruption in institutions/sectors, for instance, can point to those areas with poor reputations that may be ripe for reform. TI, who commissioned the Global Corruption Barometer from Gallup International, first ran the Global Corruption Barometer in 2003. Country coverage was expanded considerably in 2004, from 48 to 64 countries, and TI will continue to increase the number of countries polled for the Barometer. Over time, TI expects the survey to convey important trends in the way the publics around the world regard corruption in their countries.
