In the 2016 CPI report, Transparency International lamented, “Over two thirds of the 176 countries in this year’s index fall below the mid-point and that the global average scored is a paltry 43% indicating endemic corruption in many parts of the world.”
Sixty-nine percent of the 176 countries on the Corruption Perceptions Index 2016 scored below 50, on a scale from 0 (perceived to be clean) to 100 (perceived to be very highly corrupt), exposing how massive and pervasive public sector corruption is around the world.

The biggest improvers in 2017 are New Zealand, Denmark, Finland, Norway, Switzerland, Singapore, Sweden, Canada, Luxembourg, Netherlands, United Kingdom, Germany, Australia, Hong Kong, Iceland, Austria, Belgium, United States of America, Ireland, Japan, Estonia, United Arab Emirates and France among other countries.

The biggest decliners this year are Somalia, South Sudan, Syria, Afghanistan, Yemen, Sudan, Libya, Guinea Bissau, Equatorial Guinea, North Korea, Venezuela, Iraq, Turkmenistan, Angola, Eritrea, Chad, Tajikistan and Democratic Republic of the Congo among other countries.

2017 Index illustrates that around the world systemic corruption and social inequality reinforce each other, leading to popular disenchantment with political establishments and providing a fertile ground for the rise of populist politicians.

The Corruption Perceptions Index (CPI) was established in 1995 as a composite indicator used to measure perceptions of corruption in the public sector in different countries around the world. During the past 20 years, both the sources used to compile the index and the methodology has been adjusted and refined.
