Corruption perceptions index 2017

This year’s Corruption Perceptions Index highlights that the majority of countries are making little or no progress in ending corruption, while further analysis shows journalists and activists in corrupt countries risking their lives every day in an effort to speak out.

The index, which ranks 180 countries and territories by their perceived levels of public sector corruption according to experts and businesspeople, uses a scale of 0 to 100, where 0 is highly corrupt and 100 is very clean. This year, the index found that more than two-thirds of countries score below 50, with an average score of 43. Unfortunately, compared to recent years, this poor performance is nothing new.

This year, New Zealand and Denmark rank highest with scores of 89 and 88 respectively. Syria, South Sudan and Somalia rank lowest with scores of 14, 12 and 9 respectively. The best performing region is Western Europe with an average score of 66. The worst performing regions are Sub-Saharan Africa (average score 32) and Eastern Europe and Central Asia (average score 34).

Since 2012, several countries significantly improved their index score, including Côte d’Ivoire, Senegal and the United Kingdom, while several countries declined, including Syria, Yemen and Australia.

Research analysis

Further analysis of the results indicates that countries with the least protection for press and non-governmental organisations (NGOs) also tend to have the worst rates of corruption.

Every week at least one journalist is killed in a country that is highly corrupt.

The analysis, which incorporates data from the Committee to Protect Journalists, shows that in the last six years, more than 9 out of 10 journalists were killed in countries that score 45 or less on the index.

"No activist or reporter should have to fear for their lives when speaking out against corruption. Given current crackdowns on both civil society and the media worldwide, we need to do more to protect those who speak up."
