How have the G20 states (excluding the European Union) improved on corruption since the first G20 Leaders’ Summit in 2008?


Our graph shows where G20 member states rank among the more than 170 nations in the world. The data was drawn from Transparency International's annual Corruption Perceptions Index between 2008 - 2013.


Some member states combat corruption well, and some fall well short.



On average, Australia is the number one ranked G20 country.


Australia and Canada are the best performing G20 countries overall and are the only member states to have maintained a top 10 place since 2008.


Russia is considered the most corrupt member state. On average, Russia ranks among the bottom third of states in the fight against corruption. Despite this, Russia has also been most improved, increasing by 20 places from 147th in 2008 to 127th in 2013.


Collectively, the BRICS group – Brazil, Russia, India, China and South Africa – ranked 89th on average.


In contrast, the ‘Anglosphere’ member states – Australia, Canada, UK and the US – ranked 14th on average.


South Africa is the best ranked BRICS country with an average of 61.


Italy (66) struggles to combat corruption and is outperformed by Saudi Arabia (63).


Mexico displays the worst trend. The 2012 G20 host has consistently ranked worse year on year and has increased 34 places since 2008.
