The Corruption Perceptions Index 2013 serves as a reminder that the abuse of power, secret dealings and bribery continue to ravage societies around the world. The Index scores 177 countries and territories on a scale from 0 (highly corrupt) to 100 (very clean). No country has a perfect score, and two-thirds of countries score below 50. This indicates a serious, worldwide corruption problem. The world urgently needs a renewed effort to crack down on money laundering, clean up political finance, pursue the return of stolen assets and build more transparent public institutions. Iran ranked 144 out of 177 countries.
