Botswana, Cape Verde and Mauritius for the second year in a row are the least corrupt countries in Africa, though they are rather far from the two number ones of Finland and New Zealand. According to the Transparency International's Corruption Perception Index published on Wednesday, November 5, Botswana, Cape Verde and Mauritius ranked numbers 30, 39 and 43, scoring 67, 60, and 57 respectively. Other African countries that made it above the 50% mark include Rwanda and Seychelles. One of the improving countries is Nigeria, which has abandoned its perennial position of being one of the most corrupt countries in the world, to its position of No. 139 which it shares with Kenya, Nepal and Pakistan. The position of the most corrupt country in the world is Somalia and just behind is Sudan, Chad, Burundi, Zimbabwe, Equatorial Guinea and Libya in descending order. The Corruption Perceptions Index ranks countries and territories based on how corrupt their public sector is perceived to be. A country or territory’s score indicates the perceived level of public sector corruption on a scale of 0 - 100, where 0 means that a country is perceived as highly corrupt and 100 means it is perceived as very clean. A country's rank indicates its position relative to the other countries and territories included in the index. This year's index includes 176 countries and territories. According to Transparency International,
"Looking at the Corruption Perceptions Index 2012, it's clear that corruption is a major threat facing humanity. Corruption destroys lives and communities, and undermines countries and institutions. It generates popular anger that threatens to further destabilise societies and exacerbate violent conflicts. Corruption translates into human suffering, with poor families being extorted for bribes to see doctors or to get access to clean drinking water. It leads to failure in the delivery of basic services like education or healthcare. It derails the building of essential infrastructure, as corrupt leaders skim funds. Corruption amounts to a dirty tax, and the poor and most vulnerable are its primary victims."
