How does the TI Global Corruption Barometer differ from the TI Bribe Payers Index?
The Barometer is a public opinion survey, while the Bribe Payers Index is drawn from a survey of business experts. The Barometer offers the views of the general public on corruption and its impact on their lives, as well as the experience of corruption. The BPI is a measure of insider opinion on the supply side of corruption and does not include empirical data.
