(CNN) -- Somalia, Myanmar and Afghanistan have the lowest scores on Transparency International's Corruption Perceptions Index, which measures how people in 178 countries and territories view corruption in their public sectors.
On a scale of 0-10, with 10 being "very clean" and 0 being "highly corrupt," all three countries score below 1.5. Somalia is the lowest at 1.1, while Myanmar and Afghanistan are tied for second at 1.4.
At the other end of the list are Denmark, New Zealand and Singapore, which score the highest at 9.3.
The United States, with a score of 7.1, is among the countries viewed as least corrupt. It's tied for 22nd overall with Belgium. But while the U.S. is well ahead of neighbor Mexico (3.1), it seems to have some work to do to catch Canada (8.9).
The latest scores were drawn from 13 surveys and assessments published between January 2009 and September 2010 by "independent and reputable institutions," according to Transparency International. It defines corruption as the abuse of entrusted power for private gain.
Transparency International is a nongovernmental organization headquartered in Berlin. It acknowledges that corruption, by nature, is often hidden and therefore difficult to quantify, but it says it has found people's perceptions to be a reliable estimate over the long term.
Some other noteworthy scores from the index:
** Because of activist Anna Hazare and his recent hunger strike, corruption has been brought to the forefront in India.
The country scored a 3.3 on the most recent index, putting it among the countries viewed as most corrupt.
** Libya (2.2) and Syria (2.5), were also near the top of the perceived corruption list, something that might not be a surprise considering the recent unrest there. Yemen also scored a 2.2.
Egypt (3.1) and Tunisia (4.3) scored better, but not by much. Again, it's important to point out that these surveys were conducted well before these two countries' longtime leaders were ousted.
