Qatar is perceived to have the least corrupt public sector in the Middle East, according to a newly released index by Transparency International.

The Gulf nation, which tied for the 22nd spot with Chile, also comes out just above the United States and France, which are 24th and 25th, respectively.

Of the 183 countries surveyed for the 2011 Corruption Perceptions Index, two-thirds scored discouraging low – less than five out of 10, and that includes many of the so-called Arab Spring nations.

Here’s how it works:

The 2011 index draws on assessments and opinion surveys carried out by independent and reputable institutions. These surveys and assessments include questions related to the bribery of public officials, kickbacks in public procurement, embezzlement of public funds, and the effectiveness of public sector anti-corruption efforts.

Perceptions are used because corruption is to a great extent a hidden activity that is difficult to measure. Over time, perceptions have proved to be a reliable estimate of corruption.

New Zealand and Denmark enjoyed the best perception of its public sector, while North Korea and Somalia tied for last place.
