Two-thirds of the 176 countries assessed in the 2012 Index received a score of less than 50, on a scale from 0 (highly corrupt) to 100 (almost no corruption). This shows that public institutions should be more transparent and senior officials more accountable.

On December 5, Transparency International released the Corruption Perceptions Index 2012, which measures the perceived levels of public sector corruption in 176 different countries and territories around the world.
