7. Seoul (South Korea)
Total score: 37
In 2015, after South Korea’s top court ruled a law that made adultery punishable outdated, the country was confronted with an increasing rate of infidelity among spouses, where 10.8% of women said they’ve been unfaithful to their husbands. And while this percentage is substantially lower than in other entries on our list of cities with most unfaithful wives, the fact that rate for women went up by 4.3 % comparing to a similar survey in 2014 is alarming, suggesting it will rise much more in years to come.
