Hover over a country to display its Corruption Perceptions Index details.
The countries are ranked based on how corrupt the public sector is perceived to be on a scale of 0 to 100.
Two-thirds of the 175 countries listed in the 2014 index scored below 50. The average score this year is 43.
Some notable changes in this year's index include Turkey and China. Turkey dropped five points to 45/100. The perception of corruption in the Turkish government has increased drastically since last year's protests and the country's crackdown on free speech.
China's score fell four points to 36/100. In the past year a number of Chinese politicians and public officials were arrested on corruption charges.
This year's biggest improvers are Afghanistan, Côte d ́Ivoire, Egypt, Jordan, Saint Vincent and the Grenadines, and Swaziland. Denmark is in first place with a score of 92/100.
Since early November, political protests have been under way in Cambodia. The Cambodian government arrested opposition party and social activists, many of whom were convicted in a single day during "summary trials" and sentenced to a year in prison.

Angola saw a four-point drop from last year's index. In 2004, Human Rights Watch found that the country's government could not account for $4 billion spent between 1997 and 2002.

Bribery is widespread in Turkmenistan. The country's president can reportedly spend revenue from hydrocarbon sales as he wishes. No national budget has ever been published in full.

5. South Sudan

"Corruption is really the big issue," John Sopko, the special inspector general for Afghanistan reconstruction said at the Middle East Institute in Washington, D.C., in May. The U.S. government has been criticized for ignoring anti-corruption efforts in its focus on security.

Somalia has held on to its status the most corrupt country in the world for the third year in a row. Somalia is often described as many states within a state.
