PHNOM PENH, September 1, 2026 – Thailand ranks first in the world for self-reported infidelity, with 51% of married adults saying they have had sex with someone other than their partner at least once, according to the World Population Review.

Denmark came in second, followed by Germany, Italy, France, Norway, and Belgium, all with rates above 40%. Other countries like Spain, Finland, the UK, and Canada reported lower numbers, around 35%.

Experts say these figures are based on what people admit to, and the definition of cheating can differ across cultures. Still, the data offers a snapshot of how relationships vary around the world.
