Corruption Perceptions Index
Since its inception in 1995, the Corruption Perceptions Index, Transparency International’s flagship research product, has become the leading global indicator of public sector corruption. The index offers an annual snapshot of the relative degree of corruption by ranking countries and territories from all over the globe. In 2012, Transparency International revised the methodology used to construct the index to allow for comparison of scores from one year to the next.

Since its debut in 2003, the Global Corruption Barometer has surveyed the experiences of everyday people confronting corruption around the world. Through our barometer, tens of thousands of people around the globe are asked about their views and experiences, making it the only worldwide public opinion survey on corruption.
