The annual Corruption Perceptions Index (CPI), first released in 1995, is the best known of TI’s tools. It has been widely credited with putting TI and the issue of corruption on the international policy agenda.

The CPI reflects views from around the world, including those of experts who are living in the countries evaluated.

The Global Corruption Barometer (or the Barometer) is a survey that assesses general public attitudes toward and experience of corruption in dozens of countries around the world.

This report presents highlights of a brand new survey commissioned by TI, the 2008 Bribe Payers Survey. It looks in detail at the sources of corruption in the international marketplace, both in terms of where the bribes are paid and by which businesses.

Since 2001 the Global Corruption Report (GCR) has offered an annual assessment of the state of corruption around the world. The GCR brings together leading experts and practitioners to analyse current issues, new challenges and solutions in the area of corruption.
