(CNBC) The U.S. may have the world’s largest economy, but it does not even crack the top 10 percent when it comes to a perceived lack of corruption.

That is just one of the findings in the 18th annual Corruption Perceptions Index released Wednesday by Transparency International, a global non-profit organization dedicated to fighting corruption.

The U.S. ranked 19th out of 176 countries in this year’s index, scoring 74 on a scale of zero to 100, where zero is “highly corrupt” and 100 is “very clean.” Transparency International says it scores each country using multiple sources of data on perceived corruption in the public sector.
