I have reservations about the method used to set up this barometer. However, as always, I believe that it is always possible to improve the methodology for any index devised, once it becomes available.
Here is this years results by Trancarency International.
Here is an extract of their press statement.
The public opinion survey, published today ahead of International Anti-Corruption Day on 9 December, also found that citizens in countries across the globe continue to see political parties and parliaments as the institutions most compromised by corruption.
The Barometer, which surveys 63,199 respondents in 60 countries, offers a broad spectrum of data on common experiences of corruption, including which institutions most frequently demand bribes, where citizens see the greatest degree of corruption, and how they see both the future development of corruption and their governments' efforts to eradicate it.
“This year’s Global Corruption Barometer has made it clear that too often, people must part with their hard-earned money to pay for services that should be free”, said Transparency International Chair Huguette Labelle. “And they do not see enough commitment when they look to their governments and leaders. We are heartened though, that the public is increasingly demanding the accountability of the very institutions that most affect their lives, as this is a powerful driver of change.”
