Every year, Transparency International publishes its renowned Corruption Perceptions Index, a measure of perceived public sector corruption in 180 countries worldwide. The index, which ranges from zero (indicative of highly corrupt) to 100 (considered very clean), is one of the most accurate proxies for analyzing the prevalence of corruption on a global scale. The factors leading to these scores can vary widely, from governmental abuse of power, briberies to fraudulent activities, but all point to a breakdown in systems intended to serve citizens.
