The CPI focuses on corruption in the public sector and defines corruption as the abuse of public office for private gain. The surveys used in compiling the CPI ask questions that relate to the misuse of public power for private benefit, with a focus, for example, on bribe-taking by public officials in public procurement. The sources do not distinguish between administrative and political corruption or between petty and grand corruption.

The TI Bribe Payers Index (BPI) analyses the supply side of bribery in the countries where the bribes are paid. The survey has been conducted in 1999, 2002 and 2006. It ranks leading exporting countries including Australia, China, Hong Kong, Japan, Malaysia, Singapore, South Korea, Taiwan, and India (included in 2006) in terms of the degree to which international companies with their headquarters in those countries are likely to pay bribes abroad.

The BPI examines the success and failure of governments to control corruption abroad by companies headquartered in their countries and indicates how companies succeed in ensuring their employees comply with the demand of good business practice. Among the Asia Pacific countries, India and China rank worst. However, the results show that also the top rank countries bribe when doing business abroad.

The TI Global Corruption Barometer is a public opinion survey, carried out annually since 2003. The Barometer assesses general public attitudes toward and experience of corruption and compares corruption with other problems in society, evaluates the extent to which public and private institutions are considered corrupt, determines where the public believes corruption's impact is greatest, and asks about experience of paying bribes, and for the public's expectations concerning future levels of corruption.

The Global Corruption Barometer has surveyed corruption in political parties, police, parliament/legislature and business/private sector to be the most problematic areas in the Asia Pacific.
