No country scored a perfect 10 on the index. The “cleanest” country, New Zealand, scored a 9.5.
After New Zealand came Finland and Denmark, tied for the No. 2 spot with scores of 9.4, Sweden with a 9.3, and Singapore with a 9.2.
According to Transparency International, low levels of corruption and peace go hand-in-hand – and looking at the countries topping the index, that seems to bear out. The Guardian notes that national wealth doesn’t seem to be a reliable predictor – some wealthy countries, such as Russia, score quite poorly on the index. Russia received a score of 2.4, while poverty-stricken countries such as Botswana and Rwanda are in the top 50.
