14. US
The US is, believe it or not, fourteenth on our list of most adulterous, unfaithful countries with highest cheating rates in the world. Same logic as for China was used in the US. It is not possible to ask every citizen in the US and moreover, expect honesty from all of them. That would be a utopia for social researchers! However, some sources argue that it should be on the list as it is estimated that from 30% to 60% of all married individuals cheat.
