Disapproval of adultery particularly high in U.S., less so in France Married people having an affair is morally unacceptable 84% 79
Americans and Europeans don’t always agree on questions about morality, especially on issues related to sexuality. For instance, while just 30% in the U.S. think sex between unmarried adults is morally unacceptable, this is nonetheless significantly higher than what our 2013 poll found in Europe. And while adultery is widely frowned upon in the EU – except, notably, in France – Americans are even more likely to say having an affair is morally unacceptable.
